Hi Here I have an efficient implementation of spherical harmonics in pytorch https://docs.e3nn.org/en/latest/api/o3/o3_sh.html#e3nn.o3.cartesian_spherical_harmonics.spherical_harmonics

It sounds good. I can't say like that what could be wrong ... maybe a transpose of conjugate missing??

Very nice! This will help some people. Yes please make a PR! I will revert the last merge such that I will be able to compare the original code with...

I guess it's due to the fact that pytorch fft changed. Someone made recently a PR to call the new pytorch api functions but maybe it was not sufficient. I...


Thanks for sharing the investigation. I don't remember of anything that could explain this phenomenon. Could you plot the outputs with `plt.imshow` . Maybe by eye we can understand what's...

I have no idea

Thanks a lot for investigating the problem and find a solution. Do you want to make a pull request ?

I did't look at it, did you try to projet the SO3 signal on the sphere and plot it ?

The code downloads the data automatically. See the class Shrec17 in dataset.py
