How to solve the problem:undefined reference to `cublasGetStream_v2'

1

When I try to compile Pytorch with Caffe2 on Ubuntu, I get one problem like this:

And this is the only problem that I’ve not solved. Does anyone know how to solve this?
ps:I compiled with Ubuntu 18.04 anaconda cuda 11.7 gcc 10.3 g++10.3

Caffe2 is deprecated and I don’t know if it’s still properly building as I doubt it’s tested in a variety of configurations. Are you able to build PyTorch in your setup without Caffe2 support?

3

i can confirm that pytorch with caffe2 won’t build anymore. caffe2 codepath is no longer maintained and is removed from testing and builds.

I just tested the compilation without CAFFE2 and it installs fine！

Thanks for your answer! :smile:
