The traceback only looks like this:
Traceback (most recent call last):
  File "demo.py", line 7, in <module>
    f1_r_shift = f.conv2d(f1, r_shift_kernel, padding=1, groups=64)
RuntimeError: could not create a primitive

This morning, I tested the example on my Laptop successfully (Macbook from 2017 with 16 GB, above code takes 3 hours…). The above code crashes on a Linux computer (cpu-only, no cuda) with a Xeon 12-core and 192 GB RAM… I also reinstalled all python packages and tested python3.7 and 3.9. Running the latest torch and torch-vision versions available in pip. Same error on that machine. Any other way to debug it? I’m a bit clueless.
