Please see below for the SciPy 1.6 release notes. Greg did a great job on fixing and reconciliating boundary handling in ndimage (this has been on the roadmap for many years, and closes a whole slew of issues!). Best regards, Stéfan ----- Original message ----- From: Tyler Reddy <tyler.je.reddy(a)gmail.com> To: SciPy Developers List <scipy-dev(a)python.org>, Discussion of Numerical Python <numpy-discussion(a)python.org>, python-announce-list(a)python.org Subject: [SciPy-Dev] ANN: SciPy 1.6.0 Date: Thursday, December 31, 2020 07:58 Hi all, On behalf of the SciPy development team I'm pleased to announce the release of SciPy 1.6.0. Sources and binary wheels can be found at: https://pypi.org/project/scipy/ and at: https://github.com/scipy/scipy/releases/tag/v1.6.0 One of a few ways to install this release with pip: pip install scipy==1.6.0 ===================== SciPy 1.6.0 Release Notes ===================== SciPy 1.6.0 is the culmination of 6 months of hard work. It contains many new features, numerous bug-fixes, improved test coverage and better documentation. There have been a number of deprecations and API changes in this release, which are documented below. All users are encouraged to upgrade to this release, as there are a large number of bug-fixes and optimizations. Before upgrading, we recommend that users check that their own code does not use deprecated SciPy functionality (to do so, run your code with ``python -Wd`` and check for ``DeprecationWarning`` s). Our development attention will now shift to bug-fix releases on the 1.6.x branch, and on adding new features on the master branch. This release requires Python 3.7+ and NumPy 1.16.5 or greater. For running on PyPy, PyPy3 6.0+ is required. Highlights of this release --------------------------------- - `scipy.ndimage` improvements: Fixes and ehancements to boundary extension modes for interpolation functions. Support for complex-valued inputs in many filtering and interpolation functions. New ``grid_mode`` option for `scipy.ndimage.zoom` to enable results consistent with scikit-image's ``rescale``. - `scipy.optimize.linprog` has fast, new methods for large, sparse problems from the ``HiGHS`` library. - `scipy.stats` improvements including new distributions, a new test, and enhancements to existing distributions and tests New features ========== `scipy.special` improvements --------------------------------------- `scipy.special` now has improved support for 64-bit ``LAPACK`` backend `scipy.odr` improvements ---------------------------------- `scipy.odr` now has support for 64-bit integer ``BLAS`` `scipy.odr.ODR` has gained an optional ``overwrite`` argument so that existing files may be overwritten. `scipy.integrate` improvements ------------------------------------------ Some renames of functions with poor names were done, with the old names retained without being in the reference guide for backwards compatibility reasons: - ``integrate.simps`` was renamed to ``integrate.simpson`` - ``integrate.trapz`` was renamed to ``integrate.trapezoid`` - ``integrate.cumtrapz`` was renamed to ``integrate.cumulative_trapezoid`` `scipy.cluster` improvements --------------------------------------- `scipy.cluster.hierarchy.DisjointSet` has been added for incremental connectivity queries. `scipy.cluster.hierarchy.dendrogram` return value now also includes leaf color information in `leaves_color_list`. `scipy.interpolate` improvements -------------------------------------------- `scipy.interpolate.interp1d` has a new method ``nearest-up``, similar to the existing method ``nearest`` but rounds half-integers up instead of down. `scipy.io` improvements -------------------------------- Support has been added for reading arbitrary bit depth integer PCM WAV files from 1- to 32-bit, including the commonly-requested 24-bit depth. `scipy.linalg` improvements ------------------------------------- The new function `scipy.linalg.matmul_toeplitz` uses the FFT to compute the product of a Toeplitz matrix with another matrix. `scipy.linalg.sqrtm` and `scipy.linalg.logm` have performance improvements thanks to additional Cython code. Python ``LAPACK`` wrappers have been added for ``pptrf``, ``pptrs``, ``ppsv``, ``pptri``, and ``ppcon``. `scipy.linalg.norm` and the ``svd`` family of functions will now use 64-bit integer backends when available. `scipy.ndimage` improvements ------------------------------------------ `scipy.ndimage.convolve`, `scipy.ndimage.correlate` and their 1d counterparts now accept both complex-valued images and/or complex-valued filter kernels. All convolution-based filters also now accept complex-valued inputs (e.g. ``gaussian_filter``, ``uniform_filter``, etc.). Multiple fixes and enhancements to boundary handling were introduced to `scipy.ndimage` interpolation functions (i.e. ``affine_transform``, ``geometric_transform``, ``map_coordinates``, ``rotate``, ``shift``, ``zoom``). A new boundary mode, ``grid-wrap`` was added which wraps images periodically, using a period equal to the shape of the input image grid. This is in contrast to the existing ``wrap`` mode which uses a period that is one sample smaller than the original signal extent along each dimension. A long-standing bug in the ``reflect`` boundary condition has been fixed and the mode ``grid-mirror`` was introduced as a synonym for ``reflect``. A new boundary mode, ``grid-constant`` is now available. This is similar to the existing ndimage ``constant`` mode, but interpolation will still performed at coordinate values outside of the original image extent. This ``grid-constant`` mode is consistent with OpenCV's ``BORDER_CONSTANT`` mode and scikit-image's ``constant`` mode. Spline pre-filtering (used internally by ``ndimage`` interpolation functions when ``order >= 2``), now supports all boundary modes rather than always defaulting to mirror boundary conditions. The standalone functions ``spline_filter`` and ``spline_filter1d`` have analytical boundary conditions that match modes ``mirror``, ``grid-wrap`` and ``reflect``. `scipy.ndimage` interpolation functions now accept complex-valued inputs. In this case, the interpolation is applied independently to the real and imaginary components. The ``ndimage`` tutorials (https://docs.scipy.org/doc/scipy/reference/tutorial/ndimage.html) have been updated with new figures to better clarify the exact behavior of all of the interpolation boundary modes. `scipy.ndimage.zoom` now has a ``grid_mode`` option that changes the coordinate of the center of the first pixel along an axis from 0 to 0.5. This allows resizing in a manner that is consistent with the behavior of scikit-image's ``resize`` and ``rescale`` functions (and OpenCV's ``cv2.resize``). `scipy.optimize` improvements ----------------------------------------- `scipy.optimize.linprog` has fast, new methods for large, sparse problems from the ``HiGHS`` C++ library. ``method='highs-ds'`` uses a high performance dual revised simplex implementation (HSOL), ``method='highs-ipm'`` uses an interior-point method with crossover, and ``method='highs'`` chooses between the two automatically. These methods are typically much faster and often exceed the accuracy of other ``linprog`` methods, so we recommend explicitly specifying one of these three method values when using ``linprog``. `scipy.optimize.quadratic_assignment` has been added for approximate solution of the quadratic assignment problem. `scipy.optimize.linear_sum_assignment` now has a substantially reduced overhead for small cost matrix sizes `scipy.optimize.least_squares` has improved performance when the user provides the jacobian as a sparse jacobian already in ``csr_matrix`` format `scipy.optimize.linprog` now has an ``rr_method`` argument for specification of the method used for redundancy handling, and a new method for this purpose is available based on the interpolative decomposition approach. `scipy.signal` improvements -------------------------------------- `scipy.signal.gammatone` has been added to design FIR or IIR filters that model the human auditory system. `scipy.signal.iircomb` has been added to design IIR peaking/notching comb filters that can boost/attenuate a frequency from a signal. `scipy.signal.sosfilt` performance has been improved to avoid some previously- observed slowdowns `scipy.signal.windows.taylor` has been added--the Taylor window function is commonly used in radar digital signal processing `scipy.signal.gauss_spline` now supports ``list`` type input for consistency with other related SciPy functions `scipy.signal.correlation_lags` has been added to allow calculation of the lag/ displacement indices array for 1D cross-correlation. `scipy.sparse` improvements --------------------------------------- A solver for the minimum weight full matching problem for bipartite graphs, also known as the linear assignment problem, has been added in `scipy.sparse.csgraph.min_weight_full_bipartite_matching`. In particular, this provides functionality analogous to that of `scipy.optimize.linear_sum_assignment`, but with improved performance for sparse inputs, and the ability to handle inputs whose dense representations would not fit in memory. The time complexity of `scipy.sparse.block_diag` has been improved dramatically from quadratic to linear. `scipy.sparse.linalg` improvements ----------------------------------------------- The vendored version of ``SuperLU`` has been updated `scipy.fft` improvements -------------------------------- The vendored ``pocketfft`` library now supports compiling with ARM neon vector extensions and has improved thread pool behavior. `scipy.spatial` improvements --------------------------------------- The python implementation of ``KDTree`` has been dropped and ``KDTree`` is now implemented in terms of ``cKDTree``. You can now expect ``cKDTree``-like performance by default. This also means ``sys.setrecursionlimit`` no longer needs to be increased for querying large trees. ``transform.Rotation`` has been updated with support for Modified Rodrigues Parameters alongside the existing rotation representations (PR gh-12667). `scipy.spatial.transform.Rotation` has been partially cythonized, with some performance improvements observed `scipy.spatial.distance.cdist` has improved performance with the ``minkowski`` metric, especially for p-norm values of 1 or 2. `scipy.stats` improvements ------------------------------------ New distributions have been added to `scipy.stats`: - The asymmetric Laplace continuous distribution has been added as `scipy.stats.laplace_asymmetric`. - The negative hypergeometric distribution has been added as `scipy.stats.nhypergeom`. - The multivariate t distribution has been added as `scipy.stats.multivariate_t`. - The multivariate hypergeometric distribution has been added as `scipy.stats.multivariate_hypergeom`. The ``fit`` method has been overridden for several distributions (``laplace``, ``pareto``, ``rayleigh``, ``invgauss``, ``logistic``, ``gumbel_l``, ``gumbel_r``); they now use analytical, distribution-specific maximum likelihood estimation results for greater speed and accuracy than the generic (numerical optimization) implementation. The one-sample Cramér-von Mises test has been added as `scipy.stats.cramervonmises`. An option to compute one-sided p-values was added to `scipy.stats.ttest_1samp`, `scipy.stats.ttest_ind_from_stats`, `scipy.stats.ttest_ind` and `scipy.stats.ttest_rel`. The function `scipy.stats.kendalltau` now has an option to compute Kendall's tau-c (also known as Stuart's tau-c), and support has been added for exact p-value calculations for sample sizes ``> 171``. `stats.trapz` was renamed to `stats.trapezoid`, with the former name retained as an alias for backwards compatibility reasons. The function `scipy.stats.linregress` now includes the standard error of the intercept in its return value. The ``_logpdf``, ``_sf``, and ``_isf`` methods have been added to `scipy.stats.nakagami`; ``_sf`` and ``_isf`` methods also added to `scipy.stats.gumbel_r` The ``sf`` method has been added to `scipy.stats.levy` and `scipy.stats.levy_l` for improved precision. `scipy.stats.binned_statistic_dd` performance improvements for the following computed statistics: ``max``, ``min``, ``median``, and ``std``. We gratefully acknowledge the Chan-Zuckerberg Initiative Essential Open Source Software for Science program for supporting many of these improvements to `scipy.stats`. Deprecated features ================ `scipy.spatial` changes ------------------------------- Calling ``KDTree.query`` with ``k=None`` to find all neighbours is deprecated. Use ``KDTree.query_ball_point`` instead. ``distance.wminkowski`` was deprecated; use ``distance.minkowski`` and supply weights with the ``w`` keyword instead. Backwards incompatible changes ========================== `scipy` changes --------------------- Using `scipy.fft` as a function aliasing ``numpy.fft.fft`` was removed after being deprecated in SciPy ``1.4.0``. As a result, the `scipy.fft` submodule must be explicitly imported now, in line with other SciPy subpackages. `scipy.signal` changes ------------------------------- The output of ``decimate``, ``lfilter_zi``, ``lfiltic``, ``sos2tf``, and ``sosfilt_zi`` have been changed to match ``numpy.result_type`` of their inputs. The window function ``slepian`` was removed. It had been deprecated since SciPy ``1.1``. `scipy.spatial` changes ------------------------------- ``cKDTree.query`` now returns 64-bit rather than 32-bit integers on Windows, making behaviour consistent between platforms (PR gh-12673). `scipy.stats` changes ----------------------------- The ``frechet_l`` and ``frechet_r`` distributions were removed. They were deprecated since SciPy ``1.0``. Other changes ============= ``setup_requires`` was removed from ``setup.py``. This means that users invoking ``python setup.py install`` without having numpy already installed will now get an error, rather than having numpy installed for them via ``easy_install``. This install method was always fragile and problematic, users are encouraged to use ``pip`` when installing from source. - Fixed a bug in `scipy.optimize.dual_annealing` ``accept_reject`` calculation that caused uphill jumps to be accepted less frequently. - The time required for (un)pickling of `scipy.stats.rv_continuous`, `scipy.stats.rv_discrete`, and `scipy.stats.rv_frozen` has been significantly reduced (gh12550). Inheriting subclasses should note that ``__setstate__`` no longer calls ``__init__`` upon unpickling.

scikit-image 0.18.1
by Juan Nunez-Iglesias 23 Dec '20

23 Dec '20

Dear all, I’ve just released scikit-image 0.18.1, a small bug fix release on top of 0.18.0. Specifically: - Fix indexing error for labelling in large (>2GB) arrays (#5143, #5151) This was caused by a cdef in Cython using long rather than size_t for an indexing integer, which failed for big images in 32-bit platforms. Thanks to Riadh for the fix! - Only use retry_if_failed with recent pooch (#5148) Even though we added pooch 1.3 as an optional dependency, if the user had an *existing* pooch installation and didn’t request pooch from us, we would happily use their old pooch, but ask it to do new tricks that it didn’t know yet. This caused an error on importing skimage, because data/__init__ is executed by default. (We should fix this, but that was a bigger undertaking — I think this bandaid already makes things much better.) Enjoy! 😊 Juan.

Re: Otsu thresholding
by Juan Nunez-Iglesias 22 Dec '20

22 Dec '20

Some methods, like Li, have some special handling for nan values, but that is not uniform across all our methods, as you have seen. 😂 I would suggest: ```python t = threshold_otsu(image[np.isfinite(image)]) ``` That will only pass the non-nan, non-inf pixels to Otsu to do the calculation. Hope this helps!

scikit-image 0.18.0rc2 is out
by Juan Nunez-Iglesias 14 Dec '20

14 Dec '20

Dear skimagers, I’ve just pushed scikit-image 0.18.0 release candidate 2 to PyPI. I think this is the real one! If I don’t hear objections by tomorrow morning (~24h from the timestamp on this email), I’ll tag and (finally!) release 0.18.0. 🎉 Please try this release candidate out by using `pip install -U --pre scikit-image`. Since we have started adding further dependencies to our documentation examples, in order to run some of the examples you will need to `pip install -U --pre scikit-image[docs]`. Or, if you only want access to our new example datasets, you can use `pip install -U --pre scikit-image[data]`. Finally, if you want to systematically test this release on your machine, you can use `pip install -U --pre scikit-image[test]`, then run `pytest --pyargs skimage`. You can find the release notes below. Happy image analysis! Juan. Announcement: scikit-image 0.18.0 ================================= We're happy to announce the release of scikit-image v0.18.0! scikit-image is an image processing toolbox for SciPy that includes algorithms for segmentation, geometric transformations, color space manipulation, analysis, filtering, morphology, feature detection, and more. This release of scikit-image drops support for Python 3.6 in accordance with the `NEP-29 Python and Numpy version support community standard <https://numpy.org/neps/nep-0029-deprecation_policy.html>`_: Python 3.7 or newer is required to run this version. For more information, examples, and documentation, please visit our website: https://scikit-image.org New Features ------------ - Add the iterative Lucas-Kanade (iLK) optical flow method (#4161) - Add Feret diameter in region properties (#4379, #4820) - Add functions to compute Euler number and Crofton perimeter estimation (#4380) - Add a function to compute the Hausdorff distance (#4382) - Added 3D support for many filters in ``skimage.filters.rank``. - An experimental implementation of trainable pixel segmentation, aiming for compatibility with the scikit-learn API, has been added to ``skimage.future``. Try it out! (#4739) - Add a new function ``segmentation.expand_labels`` to dilate labels while preventing overlap (#4795) - It is now possible to pass extra measurement functions to ``measure.regionprops`` and ``regionprops_table`` (#4810) - Add rolling ball algorithm for background subtraction (#4851) - New sample images have been added in the ``data`` subpackage: ``data.eagle`` (#4922), ``data.human_mitosis`` (#4939), ``data.cells3d`` (#4951), and ``data.vortex`` (#5041). Also note that the image for ``data.camera`` has been changed due to copyright issues (#4913). - ``skimage.feature.structure_tensor`` now supports 3D (and nD) images as input (#5002) - Many thresholding methods can now receive a precomputed histogram as input, resulting in significant speedups if multiple methods are tried on the same image, or if a fast histogram method is used. (#5006) - ``measure.regionprops`` now supports multichannel intensity images (#5037) Documentation ------------- - Add an example to the flood fill tutorial (#4619) - Docstring enhancements for marching cubes and find_contours (#4641) - A new tutorial presenting a cell biology example has been added to the gallery (#4648). Special thanks to Pierre Poulain and Fred Bernard (Université de Paris and Institut Jacques Monod) for scientific review of this example! - Improve register rotation example with notes and references (#4723) - Add versionadded for new scalar type support for "scale" param in ``transform.AffineTransform`` (#4733) - New tutorial on `visualizing 3D data <https://scikit-image.org/docs/dev/auto_examples/applications/plot_3d_image_…>`_ (#4850) - Add example for 3D adaptive histogram equalization (AHE) (#4658) - Automatic formatting of docstrings for improved consistency (#4849) - Improved docstring for ``rgb2lab`` (#4839) and ``marching_cubes`` (#4846) - Improved docstring for ``measure.marching_cubes``, mentioning how to decimate a mesh using mayavi (#4846) - Document how to contribute a gallery example. (#4857) - Fix and improve entropy example (#4904) - expand the benchmarking section of the developer docs (#4905) - Improved docstring for ``util.random_noise`` (#5001) - Improved docstrings for ``morphology.h_maxima`` and ``morphology.h_minima`` (#4929). - Improved docstring for ``util.img_as_int`` (#4888). - A new example demonstrates interactive exploration of regionprops results using the PyData stack (pandas, seaborn) at <https://scikit-image.org/docs/dev/auto_examples/segmentation/plot_regionpro…>`_ (#5010). - Documentation has been added to explain `how to download example datasets <https://scikit-image.org/docs/dev/install.html#downloading-all-demo-datasets>`_ which are not installed with scikit-image (#4984). Similarly, the contributor guide has been updated to mention how to host new datasets in a gitlab repository (#4892). - The `benchmarking section of the developer documentation <https://scikit-image.org/docs/dev/contribute.html#benchmarks>`_ has been expanded (#4905). - Added links to the image.sc forum in example pages (#5094, #5096) - Added missing datasets to gallery examples (#5116, #5118) - Add farid filters in __all__, to populate the documentation (#5128, #5129) - Proofread gallery example for rank filters. (#5126, #5136) Improvements ------------ - float32 support for SLIC (#4683), ORB (#4684, #4697), BRIEF (#4685), ``pyramid_gaussian`` (#4696), Richardson-Lucy deconvolution (#4880) - In ``skimage.restoration.richardson_lucy``, computations are now done in single-precision when the input image is single-precision. This can give a substantial performance improvement when working with single precision data. - Richardson-Lucy deconvolution now has a ``filter_epsilon`` keyword argument to avoid division by very small numbers (#4823) - Add default level parameter (max-min) / 2 in ``measure.find_contours`` (#4862) - The performance of the SLIC superpixels algorithm (``skimage.segmentation.slice``) was improved for the case where a mask is supplied by the user (#4903). The specific superpixels produced by masked SLIC will not be identical to those produced by prior releases. - ``exposure.adjust_gamma`` has been accelerated for ``uint8`` images by using a look-up table (LUT) (#4966). - ``measure.label`` has been accelerated for boolean input images, by using ``scipy.ndimage``'s implementation for this case (#4945). - ``util.apply_parallel`` now works with multichannel data (#4927). - ``skimage.feature.peak_local_max`` supports now any Minkowski distance. - We now use sparse cross-correlation to accelerate local thresholding functions (#4912) - ``morphology.convex_hull_image`` now uses much less memory by checking hull inequalities in sequence (#5020) - Polygon rasterization is more precise and will no longer potentially exclude input vertices. (#5029) - Add data optional requirements to allow pip install scikit-image[data] (#5105, #5111) - OpenMP support in MSVC (#4924, #5111) - Restandardize handling of Multi-Image files (#2815, #5132) - Consistent zoom boundary behavior across SciPy versions (#5131, #5133) API Changes ----------- - ``skimage.restoration.richardson_lucy`` returns a single-precision output when the input is single-precision. Prior to this release, double-precision was always used. - The default value of ``threshold_rel`` in ``skimage.feature.corner`` has changed from 0.1 to None, which corresponds to letting ``skimage.feature.peak_local_max`` decide on the default. This is currently equivalent to ``threshold_rel=0``. - ``data.cat`` has been introduced as an alias of ``data.chelsea`` for a more descriptive name. - The ``level`` parameter of ``measure.find_contours`` is now a keyword argument, with a default value set to (max(image) - min(image)) / 2. - ``p_norm`` argument was added to ``skimage.feature.peak_local_max`` to add support for Minkowski distances. - In ``measure.label``, the deprecated ``neighbors`` parameter has been removed. (#4942) Bug fixes --------- - A bug in ``label2rgb`` has been fixed when the input image had np.uint8 dtype (#4661) - Fixed incorrect implementation of ``skimage.color.separate_stains`` (#4725) - Many bug fixes have been made in ``peak_local_max`` (#2592, #4756, #4760, #5047) - Fix bug in ``random_walker`` when input labels have negative values (#4771) - PSF flipping is now correct for Richardson-Lucy deconvolution work in >2D (#4823) - Fix equalize_adapthist (CLAHE) for clip value 1.0 (#4828) - For the RANSAC algorithm, improved the case where all data points are outliers, which was previously raising an error (#4844) - An error-causing bug has been corrected for the ``bg_color`` parameter in ``label2rgb`` when its value is a string (#4840) - A normalization bug was fixed in ``metrics.variation_of_information`` (#4875) - Euler characteristic property of ``skimage.measure.regionprops`` was erroneous for 3D objects, since it did not take tunnels into account. A new implementation based on integral geometry fixes this bug (#4380). - In ``skimage.morphology.selem.rectangle`` the ``height`` argument controlled the width and the ``width`` argument controlled the height. They have been replaced with ``nrow`` and ``ncol``. (#4906) - ``skimage.segmentation.flood_fill`` and ``skimage.segmentation.flood`` now consistently handle negative values for ``seed_point``. - Segmentation faults in ``segmentation.flood`` have been fixed (#4948, #4972) - A segfault in ``draw.polygon`` for the case of 0-d input has been fixed (#4943). - In ``registration.phase_cross_correlation``, a ``ValueError`` is raised when NaNs are found in the computation (as a result of NaNs in input images). Before this fix, an incorrect value could be returned where the input images had NaNs (#4886). - Fix edge filters not respecting padding mode (#4907) - Use v{} for version tags with pooch (#5104, #5110) - Fix compilation error in XCode 12 (#5107, #5111) Deprecations ------------ - The ``indices`` argument in ``skimage.feature.peak_local_max`` has been deprecated. Indices will always be returned. (#4752) - In ``skimage.feature.structure_tensor``, an ``order`` argument has been introduced which will default to 'rc' starting in version 0.20. (#4841) - ``skimage.feature.structure_tensor_eigvals`` has been deprecated and will be removed in version 0.20. Use ``skimage.feature.structure_tensor_eigenvalues`` instead. - The ``skimage.viewer`` subpackage and the ``skivi`` script have been deprecated and will be removed in version 0.20. For interactive visualization we recommend using dedicated tools such as `napari <https://napari.org>`_ or `plotly <https://plotly.com>`_. In a similar vein, the ``qt`` and ``skivi`` plugins of ``skimage.io`` have been deprecated and will be removed in version 0.20. (#4941, #4954) - In ``skimage.morphology.selem.rectangle`` the arguments ``width`` and ``height`` have been deprecated. Use ``nrow`` and ``ncol`` instead. - The explicit setting ``threshold_rel=0` was removed from the Examples of the following docstrings: ``skimage.feature.BRIEF``, ``skimage.feature.corner_harris``, ``skimage.feature.corner_shi_tomasi``, ``skimage.feature.corner_foerstner``, ``skimage.feature.corner_fast``, ``skimage.feature.corner_subpix``, ``skimage.feature.corner_peaks``, ``skimage.feature.corner_orientations``, and ``skimage.feature._detect_octave``. - In ``skimage.restoration._denoise``, the warning regarding ``rescale_sigma=None`` was removed. - In ``skimage.restoration._cycle_spin``, the ``# doctest: +SKIP`` was removed. Development process ------------------- - Fix #3327: Add functionality for benchmark coverage (#3329) - Release process notes have been improved.

Re: scikit-image Digest, Vol 50, Issue 1
by Genevieve Buckley 14 Dec '20

Hi Chien-Cheng, The scikit-image release 0.18.0 is being prepared now (so hopefully it will be out soon). I think installing the release candidate will be the simplest way forward for you, until the official release 0.18.0 becomes available. You can install the latest release candidate into your anaconda environment with: pip install scikit-image==0.18.0rc2 Last, in case you are also interested to know what went wrong with trying to install the development version, I suspect the problem you had earlier is because of one of two possibilities: 1. You have not cloned the scikit-image repository from github, or 2. You have not changed directory in your terminal before running that conda install command. You'll need to move to the location of the scikit-image git repository with something like "cd Documents/Github/scikit-image" or "cd Documents\Github\scikit-image" before you can install it. There are a few other pre-requisites for a development installation (like a working C compiler, and a C++ compiler). These are listed as bullet points under the heading "Installing scikit-image for contributors" on the page you linked to: https://scikit-image.org/docs/dev/install.html#id4 I hope that helps, Genevieve On Fri, 11 Dec 2020 at 21:13, <scikit-image-request(a)python.org> wrote: > Send scikit-image mailing list submissions to > scikit-image(a)python.org > > To subscribe or unsubscribe via the World Wide Web, visit > https://mail.python.org/mailman3/lists/scikit-image.python.org/ > or, via email, send a message with subject or body 'help' to > scikit-image-request(a)python.org > > You can reach the person managing the list at > scikit-image-owner(a)python.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of scikit-image digest..." > > Today's Topics: > > 1.

Installation question about skimage developer version
by Hung, C. (Chien-Cheng) 12 Dec '20

12 Dec '20

Dear scikit team, My name is Chien-Cheng and I am trying to use scikit-image to do some image segmentation. The method I choose is called "Training segmentation" (https://scikit-image.org/docs/dev/auto_examples/segmentation/plot_trainable…). Currently, I am trying to run the example of the training method and I got a few questions. The latest skimage version I have in the Anaconda is 0.17.2. But I found the training method seems only applicable for the developer version 0.19.0.dev0 since some of the attribute in the script is missing in the version of 0.17.2 (for example, there is an error called AttributeError: module 'skimage.feature' has no attribute 'multiscale_basic_features' after running the example script with 0.17.2). Also, I cannot find the example of the training method in the version of 0.17.2 so I figure the training methods require the developer version. I have tried installing the contributor/developer version in the conda environment by following the instruction (https://scikit-image.org/docs/dev/install.html#id6) but when I was running the third comment "conda install `for i in requirements/{default,build,test}.txt; do echo -n " --file $i "; done`. The console shows me the error below: [cid:image002.jpg@01D6CFE7.99D9EF80] I really don't know what the problem might be so I would like to turn to your help. There are two questions I have so far: 1. Do I need to install the developer version to use the training methods? 2. If so, did I install the developer version with the correct procedure? If yes, how to solve the issue I have above? Looking forward to your reply, thanks! Best regards, Chien-Cheng

10 Dec '20

Hello, Although Smil is not part os Scikit-image, it may be of interest to some of you. I'm glad to announce the release 0.11.0 of Smil, our Mathematical Morphology library. Smil is a library completely written in C++ with a Python interface (thanks to Swig). This is maintenance release with some few changes. Smil is the successor of other Mathematical Morphology software we created since the 70s : Xlim, Xlim3D, Micromorph, Morph-M and now Smil. Mathematical Morphology is a discipline created at our research department in the 60s by Georges Matheron and Jean Serra. The web site of the library is : http://smil.cmm.mines-paristech.fr You can have have a quick global view of what functions are available inside Smil here : http://smil.cmm.mines-paristech.fr/publis/SmilQuickReference.pdf Release notes here : http://smil.cmm.mines-paristech.fr/doc/_release_notes.html Feel free to make comments or give some feedback.
