Error in detect_maxima_box

[haesleinhuepf]

When executing this demo notebook:
https://github.com/clEsperanto/pyclesperanto/blob/main/demos/find_local_maxima.ipynb

The function call to detect_maxima_box results in this error:

I'm working on Windows 10 and the error is reproducible on both of my GPUs: AMD Vega GPU (integrated) and NVidia RTX 3050 Laptop GPU.

I will have a look.
This is most likely a left over error from the detect_maxima issue already related there:

• Detect Maxima/Minima border effect bug clij-opencl-kernels#23
• Detect Maxima/Minima CLIc#96
• detect_maxima_box has no radius parameter #146

[StRigaud]

this works:

 cle.detect_maxima_box(in, out radius_x=5, radius_y=5, radius_z=5)

this fails:

out =  cle.detect_maxima_box(in, radius_x=5, radius_y=5, radius_z=5)

[StRigaud]

This should be fixed by:

• Fix wrond documentation in T2 CLIc#260

[StRigaud]

Fix with:

• Fix-minmax-detection-boundary CLIc#360
