This is all done now. See the documentation in https://github.com/silx-kit/pyFAI/tree/main/doc/source/usage/tutorial/Variance/Unweighted.ipynb

`python3 -X importtime -c "import pyFAI.worker"` gives a hint ... the timings are in µs.

On lintaillefer, this takes: 2.1s out of which: ``` 193.521 ms fabio 423.257 ms pyFAI.utils 435.484 ms pyFAI 1466.502 ms silx.opencl.common 1466.716 ms silx.opencl 1466.735 ms silx.opencl.common 1467.515 ms pyFAI.opencl...

The selection of the OpenCL device can be tuned with `OCL_ICD_VENDORS`. In this example I point to an ICD for a FPGA board that I don't have: ``` 54.466 ms...

Can you provide some snippet or a working example ?

Hi Daniel, Thanks for the working example: this really looks like a bug, but I am not sure if it is possible to correct it. You are perfectly right: the...

For matplotlib, I think so since it is needed for the pyFAI-calib (without the GUI). By the way, pyFAI will go away from numpy.distutils packaging so there is trouble ahead...
