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
