Last version to support CUDA Capability 3.0


(Michael Borck) #1

I get you can’t keep supporting older GPUs, so this is not a complaint, just seeing if there is a way to explore torch.cuda() functionality.

I am on a Mac with a GeForce GT 750M which is of CUDA capability 3.0. (Driver CUDA 9.1, cuDNN 7, MacOSX10.13.sdk). I managed to fumble through and compiled torch-0.4.0x, cmake output detects GPU, (OpenMP, Magma and NNPACK detection fails, are these critical?).

Built using the following command:

MACOSX_DEPLOYMENT_TARGET=10.13 CC=clang CXX=clang++ python setup.py install

Builds, install, time for some PyTorch goodness. But anytime I run a “.cuda()” method I get the following:

Python 3.6.4 |Anaconda, Inc.| (default, Jan 16 2018, 12:04:33)

Type "help", "copyright", "credits" or "license" for more information.

>>> r = t.cuda()
/anaconda3/lib/python3.6/site-packages/torch/cuda/__init__.py:116: UserWarning:

    PyTorch no longer supports this GPU because it is too old.

  warnings.warn(old_gpu_warn % (d, name, major, capability[1]))

Umm… perhaps I have to install an older version. A little searching finds This post from a couple of days ago (Feb 18, 2018) suggests that compiling from source should work, no mention of version, so assume latest from githuh should be fine. A general search of the pytorch forum search finds posts offering the same advice.

Umm… have I done something wrong? Is there an environment variable I need to set? Do I need to install an older version? This page Previous Version, suggests it just a matter of

git checkout vX.X.X

And then follow the instruction in the README.md.

What is the last version of PyTorch to support CUDA capability 3.0 (or have I done something wrong with the compile options)?

Might be a stupid question, but Is it working?
This thread suggests to ignore the warning as far as I understand. :wink:

Thanks for the link. Umm… did ‘r’ above initialise?

<snip>
>>> r

 0.2959
 0.1837
 0.4290
[torch.cuda.FloatTensor of size 3 (GPU 0)]
>>>

It does appear to have created a torch.cuda.FLoatTensor. Does this mean is ‘working’?

Cheers,

Michael.


#4

yes that means it’s working :slight_smile:

We are using laptop to debug and compute only on dev box. Its any way to support 5.0 in future releases?
