By this I meant when only using CPU, not GPU.

bug#65127: Python-pytorch slow

2023-08-09 Thread Spencer Skylar Chan 
Hi Cayento,

Pytorch in Guix is not built with GPU support, so it will always use
the CPU even if a GPU is available. You can check the configuration
with =guix shell python-pytorch python -- python3 -c 'import torch;
print(torch.__config__.show())'=

Best,
Skylar

Hi guix,

  I just noticed that the following line (latest guix, as for today)

guix shell -C --emulate-fhs --network python python-pytorch 
python-torchvision -- python3 quickstart_tutorial.py

  with

  is noticeably slower than the version of the torch suite provided by
  conda, for example.

Thanks,
