I was running pytorch on a Ubuntu 20.04 machine that was equipped with a cudatoolkit==11.4. Previously I installed pytorch==1.10.1+cu111
and everything goes fine. However, yesterday I reinstalled pytorch with pytorch==1.12.1+cu113
and the model performance drops 10
percentage.
There are two things to note:
- not all the models’ performance dropped, only several of them
- I’m not training any new model, I just tested the existing checkpoint with the same code and input.
After reinstalling the pytorch==1.10.1+cu111
, everything is fine again.
Anyone can tell the reason? Or providing some resources of the compatability of different cuda version?
