Pre-built pytorch for CUDA [compute capability] 3.0 on windows?

[KFrank]

Hi Peter and Pu!

Thanks for your help getting pytorch working with my old cuda
compute capability 3.0 gpu. Thanks also to Andrei for his
post (in the thread linked to below) for the observation
that helped get me past my sticking point.

I will select Peter’s post linking to the legacy builds as the
solution although the whole discussion has been helpful.

The solution (for me) is to use a work-around for the
“cuda runtime error (30)” issue – namely don’t call
torch.cuda.is_available().

I was led to this by this post in the thread linked to by Peter:

[resolved] Cuda Runtime Error(30)

This always works for me (Win10, Cuda 10.1, Python 3.7.2, PyTorch 1.0.1, NVIDIA GTX 1050 Ti): import torch torch.cuda.current_device() but this always fails for me: import torch torch.cuda.is_available() torch.cuda.current_device() # fails here @Mohamed_Ghadban, how can I access the NVIDIA Nsight Options? Thanks in advance

I’ve posted some observations about “cuda runtime error (30)” here:

Some observations on "cuda runtime error (30)"

Hello Forum! I have some information about the behavior of “cuda runtime error (30)” (probably somewhat specific to my particular configuration). This is a follow-on to a number of threads about “error 30,” and, in particular, to this post: https://discuss.pytorch.org/t/resolved-cuda-runtime-error-30/1116/20 Clued in by Andrei’s observation that torch.cuda.is_available() “breaks” cuda, I find (for me) that if torch.cuda.is_available() is the first cuda call, subsequent cuda calls will t…

Here is a script showing some simple gpu-tensor manipulations:

import torch
print (torch.__version__)
torch.cuda.get_device_capability (0)
torch.cuda.get_device_name (0)
ct = torch.cuda.FloatTensor([[3.3, 4.4, 5.5], [6.6, 7.7, 8.8]])
ct
ct + 0.01 * ct
quit()

And here is the output:

 6.6660  7.7770  8.8880

>>> quit()

I’ll follow up if I have any issues actually running models on
this gpu.

Thanks again.
