PyTorch problem

Here is my related env variables:

Subject: Re: PyTorch problem

If the CUDA examples work for anyone, can they share their PATH and LD_LIBRARY_PATH variables?

Thanks

I think with Biswajit’s and my problem with cuda, we should isolate the problem with just CUDA (and drivers) instead of wandering around python or pytorch.
Predrag can you test the CUDA examples? I sort of agree with Manzil that this might be a user account problem.

Thanks,
Yichong

I just tried Yichong's way of testing cuBLAS, and get the same error as earlier:

[Matrix Multiply CUBLAS] - Starting...
GPU Device 0: "TITAN Xp" with compute capability 6.1

MatrixA(640,480), MatrixB(480,320), MatrixC(640,320)
CUDA error at matrixMulCUBLAS.cpp:275 code=1(CUBLAS_STATUS_NOT_INITIALIZED) "cublasCreate(&handle)"

So I believe it is not a conda error. I also tried removing .nv, doesn't help either. Maybe someone can share the PATH env variable?

Manzil, could you share your `conda env export` (or equivalent) output for the environment you use for pytorch? It's still not working for me after reboot, maybe I can try replicating your exact setup and try with that.

Thanks,

Emre

Aha! Gotcha.

That was my hunch as well. They were trying to convince me in a 150
e-mails chain over the weekend that pytorch was broken when I replaced a
failed HDD on the main file server. That didn't make any sense.

Could you please share your binaries and setup with outher pytorch
users?

Cheers,
Predrag

> OK so here?s a further test: I tried running the cuda examples from the cuda installation (in /usr/local/cuda/sample), on gpu2 in my scratch directory. Simple jobs like deviceQuery succeeds, but simpleCUBLAS failed:
