How to display a RGB image (MFISH)?
by jp April 3, 2023

April 3, 2023

Hi, I have written a script to try to combine five images into a three channels RGB images<http://dip4fish.blogspot.com/2011/05/trying-to-combine-mfish-images-into-rg…> . The resulting RGB image looks like a grey scale image instead of a color one. I have three np.array Rnorm, Gnorm, Bnorm which are copied into a rgb array: *rgb = np.zeros((shape[0],shape[1],3),dtype=float) mxr=np.max(R) mxg=np.max(G) mxb=np.max(B) Rnorm=np.uint8((255*(R/mxr)))Gnorm=np.uint8((255*(R/mxg)))Bnorm=np.uint8((255*(R/mxb)))#copy each RGB component in an RGB array rgb[:,:,0]=Rnorm rgb[:,:,1]=Gnorm rgb[:,:,2]=Bnorm* *pylab.subplot(224, aspect='equal',frameon=False, xticks=[], yticks=[]) pylab.imshow(rgb) pylab.show()* Any advice? Thank you Jean-Patrick

Wanting to take a FFT transform of a irregularly spaced sample
by ashwin .D May 18, 2022

May 18, 2022

Hello, I have looked at both these answers from SO - https://stackoverflow.com/questions/34428886/discrete-fourier-transformatio… and https://stackoverflow.com/questions/25735153/plotting-a-fast-fourier-transf… My question is somewhat similar. I have data from a CSV file that has measurements of a mean sea level pressure. The data is available every 5 minutes. That means 8928 sample points over a month. But during a hurricane event there was a power failure and only 8867 data points are available. I am short by 61 points to get a uniformly spaced sample. I am wanting to take an FFT of the data in order to check for periodicity, waves and frequencies there of. What are my best options ? Best regards, Ashwin.

NumPy 1.21.6 released
by Charles R Harris April 12, 2022

April 12, 2022

Hi All, On behalf of the NumPy team I am pleased to announce the release of NumPy 1.21.6. NumPy 1.21.6 is a very small release that achieves two things: - Backs out the mistaken backport of C++ code into 1.21.5. - Provides a 32 bit Windows wheel for Python 3.10. The provision of the 32 bit wheel is intended to make life easier for oldest-supported-numpy. The Python versions supported in this release are 3.7-3.10. If you want to compile your own version using gcc-11 you will need to use gcc-11.2+ to avoid problems. Wheels can be downloaded from PyPI <https://pypi.org/project/numpy/1.21.6/>; source archives, release notes, and wheel hashes are available on Github <https://github.com/numpy/numpy/releases/tag/v1.21.6>. Linux users will need pip >= 0.19.3 in order to install manylinux2010 and manylinux2014 wheels. A recent version of pip is needed to install the universal2 macos wheels. Cheers, Charles Harris

ANN: pvlib-0.9.1 released
by Dr. Mark Alexander Mikofski PhD April 2, 2022

April 2, 2022

Dear Pythonistas and solar power enthusiasts, On behalf of the maintainers, we're happy to announce a new release of pvlib python: software for simulating performance of photovoltaic solar energy systems. *See what's new for v0.9.1:* * https://pvlib-python.readthedocs.io/en/stable/whatsnew.html *Releases are available from PyPI and the conda-forge channel:* * https://pypi.org/project/pvlib/ * https://anaconda.org/conda-forge/pvlib-python *Read the Documentation:* * https://pvlib-python.readthedocs.io/en/stable/index.html *Report issues & contribute:* * https://github.com/pvlib/pvlib-python *Highlights:* ** *Beautifully updated documentation theme that is easier to browse and navigate. Please share your feedback! * Implementation of pvlib.temperature.prilliman <https://pvlib-python.readthedocs.io/en/stable/reference/generated/pvlib.tem…>, a transient weighted moving-average temperature model by Prilliman, *et al.*, to calculate back of module temperature from high-frequency sub-hourly irradiance input to account for different characteristic timescales between heat transfer and power conversion. * New infinite sheds model for either bifacial or monofacial modules, that calculates row-to-row shading and view factors for sky and ground reflected diffuse irradiance. Use pvlib.bifacial.infinite_sheds.get_irradiance <https://pvlib-python.readthedocs.io/en/stable/reference/generated/pvlib.bif…> to calculate the plane of array irradiance, all its components on both front and back sides, and the total from both sides. *The maintainers thank you for using pvlib python!* -- Mark Mikofski, PhD (2005) *Fiat Lux*
