I’ve asked to ports@freebsd.org. He told me : " I have tried quickly build the PyTorch on FreeBSD but it did
not build out of the box… that means more work is required to run it here… considering size of the project a person more familiar and interested needs to be found that would create and maintain the PyTorch related ports, sorry, at this point you can try to request a build for FreeBSD on the upstream (but there may be no interest) and use other platform to get things working straight away… you can also spend some time to make it work on FreeBSD what could be a nice learning process :-). So considered that this task requires an high level of programming skills that I don’t have,I think that this is the end of this challenge.
