ANN: NumPy 1.8.0 release.
by Charles R Harris Oct. 30, 2013

Oct. 30, 2013

I am pleased to announce the availability of NumPy 1.8.0. This release is the culmination of over a years worth of work by the NumPy team and contains many fixes, enhancements, and new features. Highlights are: - New, no 2to3, Python 2 and Python 3 are supported by a common code base. - New, gufuncs for linear algebra, enabling operations on stacked arrays. - New, inplace fancy indexing for ufuncs with the ``.at`` method. - New, ``partition`` function, partial sorting via selection for fast median. - New, ``nanmean``, ``nanvar``, and ``nanstd`` functions skipping NaNs. - New, ``full`` and ``full_like`` functions to create value initialized arrays. - New, ``PyUFunc_RegisterLoopForDescr``, better ufunc support for user dtypes. - Numerous performance improvements in many areas. This release requires Python 2.6, 2.7 or 3.2-3.3, support for Python 2.4 and 2.5 has been dropped. Sources and binaries can be found at http://sourceforge.net/projects/numpy/files/NumPy/1.8.0/. Some 119 people contributed to this release. This is a remarkable increase and shows that there is still life in this venerable code that had its beginning in Numeric some 18 years ago. Many thanks to you all. Enjoy, Chuck NumPy 1.8.0 Release Notes ************************* This release supports Python 2.6 -2.7 and 3.2 - 3.3. Highlights ========== * New, no 2to3, Python 2 and Python 3 are supported by a common code base. * New, gufuncs for linear algebra, enabling operations on stacked arrays. * New, inplace fancy indexing for ufuncs with the ``.at`` method. * New, ``partition`` function, partial sorting via selection for fast median. * New, ``nanmean``, ``nanvar``, and ``nanstd`` functions skipping NaNs. * New, ``full`` and ``full_like`` functions to create value initialized arrays. * New, ``PyUFunc_RegisterLoopForDescr``, better ufunc support for user dtypes. * Numerous performance improvements in many areas. Dropped Support =============== Support for Python versions 2.4 and 2.5 has been dropped, Support for SCons has been removed. Future Changes ============== The Datetime64 type remains experimental in this release. In 1.9 there will probably be some changes to make it more useable. The diagonal method currently returns a new array and raises a FutureWarning. In 1.9 it will return a readonly view. Multiple field selection from a array of structured type currently returns a new array and raises a FutureWarning. In 1.9 it will return a readonly view. The numpy/oldnumeric and numpy/numarray compatibility modules will be removed in 1.9. Compatibility notes =================== The doc/sphinxext content has been moved into its own github repository, and is included in numpy as a submodule. See the instructions in doc/HOWTO_BUILD_DOCS.rst.txt for how to access the content. .. _numpydoc: https://github.com/numpy/numpydoc The hash function of numpy.void scalars has been changed. Previously the pointer to the data was hashed as an integer. Now, the hash function uses the tuple-hash algorithm to combine the hash functions of the elements of the scalar, but only if the scalar is read-only. Numpy has switched its build system to using 'separate compilation' by default. In previous releases this was supported, but not default. This should produce the same results as the old system, but if you're trying to do something complicated like link numpy statically or using an unusual compiler, then it's possible you will encounter problems. If so, please file a bug and as a temporary workaround you can re-enable the old build system by exporting the shell variable NPY_SEPARATE_COMPILATION=0. For the AdvancedNew iterator the ``oa_ndim`` flag should now be -1 to indicate that no ``op_axes`` and ``itershape`` are passed in. The ``oa_ndim == 0`` case, now indicates a 0-D iteration and ``op_axes`` being NULL and the old usage is deprecated. This does not effect the ``NpyIter_New`` or ``NpyIter_MultiNew`` functions. The functions nanargmin and nanargmax now return np.iinfo['intp'].min for the index in all-NaN slices. Previously the functions would raise a ValueError for array returns and NaN for scalar returns. NPY_RELAXED_STRIDES_CHECKING ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ There is a new compile time environment variable ``NPY_RELAXED_STRIDES_CHECKING``. If this variable is set to 1, then numpy will consider more arrays to be C- or F-contiguous -- for example, it becomes possible to have a column vector which is considered both C- and F-contiguous simultaneously. The new definition is more accurate, allows for faster code that makes fewer unnecessary copies, and simplifies numpy's code internally. However, it may also break third-party libraries that make too-strong assumptions about the stride values of C- and F-contiguous arrays. (It is also currently known that this breaks Cython code using memoryviews, which will be fixed in Cython.) THIS WILL BECOME THE DEFAULT IN A FUTURE RELEASE, SO PLEASE TEST YOUR CODE NOW AGAINST NUMPY BUILT WITH:: NPY_RELAXED_STRIDES_CHECKING=1 python setup.py install You can check whether NPY_RELAXED_STRIDES_CHECKING is in effect by running:: np.ones((10, 1), order="C").flags.f_contiguous This will be ``True`` if relaxed strides checking is enabled, and ``False`` otherwise. The typical problem we've seen so far is C code that works with C-contiguous arrays, and assumes that the itemsize can be accessed by looking at the last element in the ``PyArray_STRIDES(arr)`` array. When relaxed strides are in effect, this is not true (and in fact, it never was true in some corner cases). Instead, use ``PyArray_ITEMSIZE(arr)``. For more information check the "Internal memory layout of an ndarray" section in the documentation. Binary operations with non-arrays as second argument ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Binary operations of the form ``<array-or-subclass> * <non-array-subclass>`` where ``<non-array-subclass>`` declares an ``__array_priority__`` higher than that of ``<array-or-subclass>`` will now unconditionally return *NotImplemented*, giving ``<non-array-subclass>`` a chance to handle the operation. Previously, `NotImplemented` would only be returned if ``<non-array-subclass>`` actually implemented the reversed operation, and after a (potentially expensive) array conversion of ``<non-array-subclass>`` had been attempted. (`bug <https://github.com/numpy/numpy/issues/3375>`_, `pull request <https://github.com/numpy/numpy/pull/3501>`_) Function `median` used with `overwrite_input` only partially sorts array ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ If `median` is used with `overwrite_input` option the input array will now only be partially sorted instead of fully sorted. Fix to financial.npv ~~~~~~~~~~~~~~~~~~~~ The npv function had a bug. Contrary to what the documentation stated, it summed from indexes ``1`` to ``M`` instead of from ``0`` to ``M - 1``. The fix changes the returned value. The mirr function called the npv function, but worked around the problem, so that was also fixed and the return value of the mirr function remains unchanged. Runtime warnings when comparing NaN numbers ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Comparing ``NaN`` floating point numbers now raises the ``invalid`` runtime warning. If a ``NaN`` is expected the warning can be ignored using np.errstate. E.g.:: with np.errstate(invalid='ignore'): operation() New Features ============ Support for linear algebra on stacked arrays ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The gufunc machinery is now used for np.linalg, allowing operations on stacked arrays and vectors. For example:: >>> a array([[[ 1., 1.], [ 0., 1.]], [[ 1., 1.], [ 0., 1.]]]) >>> np.linalg.inv(a) array([[[ 1., -1.], [ 0., 1.]], [[ 1., -1.], [ 0., 1.]]]) In place fancy indexing for ufuncs ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The function ``at`` has been added to ufunc objects to allow in place ufuncs with no buffering when fancy indexing is used. For example, the following will increment the first and second items in the array, and will increment the third item twice: ``numpy.add.at(arr, [0, 1, 2, 2], 1)`` This is what many have mistakenly thought ``arr[[0, 1, 2, 2]] += 1`` would do, but that does not work as the incremented value of ``arr[2]`` is simply copied into the third slot in ``arr`` twice, not incremented twice. New functions `partition` and `argpartition` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New functions to partially sort arrays via a selection algorithm. A ``partition`` by index ``k`` moves the ``k`` smallest element to the front of an array. All elements before ``k`` are then smaller or equal than the value in position ``k`` and all elements following ``k`` are then greater or equal than the value in position ``k``. The ordering of the values within these bounds is undefined. A sequence of indices can be provided to sort all of them into their sorted position at once iterative partitioning. This can be used to efficiently obtain order statistics like median or percentiles of samples. ``partition`` has a linear time complexity of ``O(n)`` while a full sort has ``O(n log(n))``. New functions `nanmean`, `nanvar` and `nanstd` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New nan aware statistical functions are added. In these functions the results are what would be obtained if nan values were ommited from all computations. New functions `full` and `full_like` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ New convenience functions to create arrays filled with a specific value; complementary to the existing `zeros` and `zeros_like` functions. IO compatibility with large files ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Large NPZ files >2GB can be loaded on 64-bit systems. Building against OpenBLAS ~~~~~~~~~~~~~~~~~~~~~~~~~ It is now possible to build numpy against OpenBLAS by editing site.cfg. New constant ~~~~~~~~~~~~ Euler's constant is now exposed in numpy as euler_gamma. New modes for qr ~~~~~~~~~~~~~~~~ New modes 'complete', 'reduced', and 'raw' have been added to the qr factorization and the old 'full' and 'economic' modes are deprecated. The 'reduced' mode replaces the old 'full' mode and is the default as was the 'full' mode, so backward compatibility can be maintained by not specifying the mode. The 'complete' mode returns a full dimensional factorization, which can be useful for obtaining a basis for the orthogonal complement of the range space. The 'raw' mode returns arrays that contain the Householder reflectors and scaling factors that can be used in the future to apply q without needing to convert to a matrix. The 'economic' mode is simply deprecated, there isn't much use for it and it isn't any more efficient than the 'raw' mode. New `invert` argument to `in1d` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The function `in1d` now accepts a `invert` argument which, when `True`, causes the returned array to be inverted. Advanced indexing using `np.newaxis` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ It is now possible to use `np.newaxis`/`None` together with index arrays instead of only in simple indices. This means that ``array[np.newaxis, [0, 1]]`` will now work as expected and select the first two rows while prepending a new axis to the array. C-API ~~~~~ New ufuncs can now be registered with builtin input types and a custom output type. Before this change, NumPy wouldn't be able to find the right ufunc loop function when the ufunc was called from Python, because the ufunc loop signature matching logic wasn't looking at the output operand type. Now the correct ufunc loop is found, as long as the user provides an output argument with the correct output type. runtests.py ~~~~~~~~~~~ A simple test runner script ``runtests.py`` was added. It also builds Numpy via ``setup.py build`` and can be used to run tests easily during development. Improvements ============ IO performance improvements ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Performance in reading large files was improved by chunking (see also IO compatibility). Performance improvements to `pad` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The `pad` function has a new implementation, greatly improving performance for all inputs except `mode=<function>` (retained for backwards compatibility). Scaling with dimensionality is dramatically improved for rank >= 4. Performance improvements to `isnan`, `isinf`, `isfinite` and `byteswap` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ `isnan`, `isinf`, `isfinite` and `byteswap` have been improved to take advantage of compiler builtins to avoid expensive calls to libc. This improves performance of these operations by about a factor of two on gnu libc systems. Performance improvements via SSE2 vectorization ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Several functions have been optimized to make use of SSE2 CPU SIMD instructions. * Float32 and float64: * base math (`add`, `subtract`, `divide`, `multiply`) * `sqrt` * `minimum/maximum` * `absolute` * Bool: * `logical_or` * `logical_and` * `logical_not` This improves performance of these operations up to 4x/2x for float32/float64 and up to 10x for bool depending on the location of the data in the CPU caches. The performance gain is greatest for in-place operations. In order to use the improved functions the SSE2 instruction set must be enabled at compile time. It is enabled by default on x86_64 systems. On x86_32 with a capable CPU it must be enabled by passing the appropriate flag to the CFLAGS build variable (-msse2 with gcc). Performance improvements to `median` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ `median` is now implemented in terms of `partition` instead of `sort` which reduces its time complexity from O(n log(n)) to O(n). If used with the `overwrite_input` option the array will now only be partially sorted instead of fully sorted. Overrideable operand flags in ufunc C-API ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ When creating a ufunc, the default ufunc operand flags can be overridden via the new op_flags attribute of the ufunc object. For example, to set the operand flag for the first input to read/write: PyObject \*ufunc = PyUFunc_FromFuncAndData(...); ufunc->op_flags[0] = NPY_ITER_READWRITE; This allows a ufunc to perform an operation in place. Also, global nditer flags can be overridden via the new iter_flags attribute of the ufunc object. For example, to set the reduce flag for a ufunc: ufunc->iter_flags = NPY_ITER_REDUCE_OK; Changes ======= General ~~~~~~~ The function np.take now allows 0-d arrays as indices. The separate compilation mode is now enabled by default. Several changes to np.insert and np.delete: * Previously, negative indices and indices that pointed past the end of the array were simply ignored. Now, this will raise a Future or Deprecation Warning. In the future they will be treated like normal indexing treats them -- negative indices will wrap around, and out-of-bound indices will generate an error. * Previously, boolean indices were treated as if they were integers (always referring to either the 0th or 1st item in the array). In the future, they will be treated as masks. In this release, they raise a FutureWarning warning of this coming change. * In Numpy 1.7. np.insert already allowed the syntax `np.insert(arr, 3, [1,2,3])` to insert multiple items at a single position. In Numpy 1.8. this is also possible for `np.insert(arr, [3], [1, 2, 3])`. Padded regions from np.pad are now correctly rounded, not truncated. C-API Array Additions ~~~~~~~~~~~~~~~~~~~~~ Four new functions have been added to the array C-API. * PyArray_Partition * PyArray_ArgPartition * PyArray_SelectkindConverter * PyDataMem_NEW_ZEROED C-API Ufunc Additions ~~~~~~~~~~~~~~~~~~~~~ One new function has been added to the ufunc C-API that allows to register an inner loop for user types using the descr. * PyUFunc_RegisterLoopForDescr Deprecations ============ The 'full' and 'economic' modes of qr factorization are deprecated. General ~~~~~~~ The use of non-integer for indices and most integer arguments has been deprecated. Previously float indices and function arguments such as axes or shapes were truncated to integers without warning. For example `arr.reshape(3., -1)` or `arr[0.]` will trigger a deprecation warning in NumPy 1.8., and in some future version of NumPy they will raise an error.

devpi 1.2 releases: many improvements + py33 support
by holger krekel Oct. 30, 2013

Oct. 30, 2013

The devpi-{server,client}-1.2 releases bring a lot of refinements and improvements for serving and interacting with your own pypi indexes: - devpi-server serves release files from URLs containing a MD5 hash allowing safe serving of those files through nginx - devpi-server's USER/INDEX urls can now be used directly with pip/easy_install without the previously required (and still valid) ``+simple/`` suffix. - ``devpi use --set-cfg`` reads and writes pip/easy_install configuration files, making those installers pick up the in-use index seemlessly. You can even do ``devpi use --always-set-cfg`` to always set those config files when issuing a "devpi use" afterwards. - ``devpi upload`` got many improvements: - versioned files (git and hg) will be exported to a clean directory prior to the build step - distutils/setup.py is now only used for building a package - documentation upload is tied to a version now - you can directly upload distribution files, including wheel files - both devpi-server and devpi-client are python3.3 compatible now and depend on a new devpi-common package which consolidates various pypi-interaction aspects to avoid code duplication. Also, global http proxy settings are honoured. If you have an existing devpi-server-1.1 installation serving your own packages you can install devpi-server>=1.2 and migrate the data with:: devpi-server --upgrade-state [--serverdir your_server_dir] This upgrades your server state in-place. Please make sure you backup your serverdir ahead of doing the upgrade (default location is ~/.devpi/server). WARNING: ``devpi-server --gendeploy`` is deprecated and will be removed probably in favor of just generating example config files for nginx/supervisor/cron. Also ``devpi install`` is deprecated now in favor of using pip/easy_install directly (see also the --set-cfg and --always-set-cfg options). For more information please refer to the extensive documentation at: http://doc.devpi.net/ or check the CHANGELOG below. have fun, holger krekel 1.2 ---------------------------- devpi-server: - serve links to files on simple pages and index root as relative paths so that it works more nicely with proxy-pass server setups. fixes issue56. - make devpi-server and devpi-common python3.3 compatible, addresses issue57 - use system http/s proxy settings from devpi-server. fixes issue58. - refactor locations to allow nginx serving static files more directly. Also updated nginx template accordingly. - rework "--upgrade-state" to detect the state version of the server dir and create an appropriate virtualenv with a devpi-server install in order to export data, and then import that version. - allow to use /user/index as indexserver url for pip/easy_install by redirecting non-json queries to /user/index/PROJ[/] to /user/index/+simple/PROJ/ - fix submission of multi-value fields like "classifiers" or "platform" (previously they would be wrongly collapsed to become the last value of a list) - fix normalization import/export issue: pypi names take precendence for defining the "real" name of a project. - always store uploaded documentation with a version. While "devpi upload" will make sure to pass in the version, "setup.py upload_docs" will not pass in a version. In the latter case, devpi-server assumes the documentation belongs to the highest yet registered release. This change requires exporting with devpi-1.1 and importing with devpi-1.2 in order to properly store versioned docs internally. - use types/url/metadata/validation functionality of new depdency devpi_common - internal cleanup using pytest-flakes - make devpi-server use a proper UserAgent string devpi-client: - "devpi list" and "devpi remove" now accept a pip/setuptools style requirement like "pkg>=1.0" instead of the former for limited "pkg-1.0". - make devpi-client fully work with python3.3 and fix test bugs - use system http/s proxy settings. fixes issue58. - add "devpi test -c tox.ini package" to use a particular (external) tox.ini for running tox with the unpackaged package. also add "--fallback-ini tox.ini" option which will only be used if the download package has no tox.ini. - new "devpi use --set-cfg" option to set pip/easy_install configuration files when changing indexes. Also new "devpi use --always-set-cfg=yes" option if you want to imply "--set-cfg" on future "devpi use" invocations and "devpi use --always-st-cfg=no" to disable this implication. - support git and hg for exporting all versioned files of a directory before performing the build step when uploading - improve how upload works: setup.py is only used for building docs and release files but not for the remote upload part. This gets rid of a number of hacks that were done trying to get the Python shipped "distutils" to pick the proper devpi index and allows proper SSL verification on Python2.6 onwards. - upload: show response when uploading documentation failed - upload: allow to specify archive files as positional arguments (both files and directories can be specified but the latter additionally require a --upload-dirs option) - fix issue54: upload now works on wheel files as well. As pkginfo does not support wheels directly, we use the ``twine`` project which extends pkginfo for now. - only show highest version in "devpi list PROJECT" output, unless "--all" is specified. - on upload release files: skip rather than guess packages which contain no metadata - strike BeautifulSoup dependency and re-use vendored pip-link parser - use types/url/metadata/validation functionality of new depdency devpi_common - internal cleanup wrt pytest-flakes discoveries - remove "archive" dependency in favour of a small implementation in devpi_common - make devpi-client use a proper UserAgent string

[ANN] jsonrpclib-pelix 0.1.6
by Thomas Calmant Oct. 23, 2013

Oct. 23, 2013

====================== jsonrpclib-pelix 0.1.6 ====================== jsonrpclib-pelix v0.1.6 has been released ! About jsonrpclib-pelix ====================== This library is an implementation of the JSON-RPC specification. It supports both the original 1.0 specification, as well as the 2.0 specification, which includes batch submission, keyword arguments, etc. This is a patched version of the original jsonrpclib project by Josh Marshall, available at https://github.com/joshmarshall/jsonrpclib. The suffix -pelix only indicates that this version works with Pelix Remote Services, but it is not a Pelix specific implementation. jsonrpclib-pelix supports both Python 2 (tested on 2.7) and Python 3 (tested on 3.2). It is licensed under the Apache License, Version 2.0 (http://www.apache.org/licenses/LICENSE-2.0.html). What's new in 0.1.6 =================== - Corrected a bug in the unmarshalling process: now beans can be correctly used in RPC - Corrected a bug on Python 2.7: the io module was imported instead of StringIO - The configuration of a jsonrpclib server or client can now be an instance of the Config class, instead of using a singleton. This allows to use mutliple servers/clients with different configurations. jsonrpclib-pelix is available on : - PyPI: https://pypi.python.org/pypi/jsonrpclib-pelix/0.1.6 - Github: https://github.com/tcalmant/jsonrpclib Have fun !

What is cx_Freeze? cx_Freeze is a set of scripts and modules for freezing Python scripts into executables, in much the same way that py2exe and py2app do. Unlike these two tools, cx_Freeze is cross platform and should work on any platform that Python itself works on. It supports Python 2.3 or higher, including Python 3. Where do I get it? http://cx-freeze.sourceforge.net What's new? The release notes can be read here as well: http://cx_freeze.readthedocs.org/en/latest/releasenotes.html 1) Added support for Python 3.4. 2) Added hooks for PyQt4, PyQt5 and PySide to handle their plugins. 3) Added support for creating a shortcut/alias to the Applications directory within distributed DMG files for OS X. 4) Improve missing modules output. 5) Avoid polluting the extension module namespace when using the bootstrap module to load the extension. 6) Added support for using setuptools and pip if such tools are available. 7) Added first tests; nose and mock are required to run them. 8) Remove --bundle-iconfile in favor of --iconfile as a more generic method of including the icon for bdist_mac. 9) Documentation improved and FAQ added. 10) Converted samples to follow PEP 8. Bugs fixed: * cxfreeze-quickstart failed if the default base was not used * scripts frozen with Python 3 fail with an ImportError trying to import the re module * fix bug where after a first attempt to find a module failed, the second attempt would erroneously succeed * stop attempting to load a module by a name that is not a valid Python identifier
