Indeed I did some quick fixes last year to get torch 1.3 compiled on RPI. However, all the unit tests didn’t pass (this is why I didn’t event try a PR or something), but the main commonly used torch functions are working just as they should. I can make some digging and find out what I did last year, but I got no time for this right now , moreover, I think it doesn’t matter that much.
I’ll probably do the same for torch 1.4 in the coming weeks or months.
