Python-pytorch slow

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

https://raw.githubusercontent.com/pytorch/tutorials/main/beginner_source/basics/quickstart_tutorial.py

is noticeably slower than the version of the torch suite provided by

conda, for example.

Thanks,

Cayetano Santos

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

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