Good morning
are there some recent and in-depth (step-by-step) guides on build and compiling Pytorch on Ubuntu?
I’have followed GitHub - pytorch/pytorch: Tensors and Dynamic neural networks in Python with strong GPU acceleration 6 but perhaps it requires some knowledge that I don’t known (I’m “middle” user of Ubuntu… I’m never compiled anything!).
Or it exists some general guides but with very similar passages?
I have done a lot of proofs of pytorch compiling but I have received many errors.
For example it said me to have installed pytorch1.9 (why not 1.8?) in conda evniroment where I have builded it (and I make also “conda list” to check version), but when I make print pytorch version it writes pytorch 1.5…
And this version works, but it gives smaller accuracy (-20%) of pytorch 1.8.
I don’t understand why… 
Thank you
