I have a text classifier in pytorch and I want to use GPUs to increase running speed. I have used this part of code to check CUDA and use it:
if torch.cuda.device_count() > 1:
print("Let's use", torch.cuda.device_count(), "GPUs!")
my_rnn_model = nn.DataParallel(my_rnn_model)
if torch.cuda.is_available():
my_rnn_model.cuda()
Now I want to return back to use cpu (instead of gpu). So I cleared this part of code. But it does'nt work and I receive this error:
RuntimeError: cuda runtime error (8) : invalid device function at /opt/conda/conda-bld/pytorch_1503963423183/work/torch/lib/THC/THCTensorCopy.cu:204
Would you please guide me how can I return back to cpu running?
You can set the GPU device that you want to use using:
device = torch.device('cuda:0' if torch.cuda.is_available() else 'cpu')
And in your case just you can return to CPU using:
torch.device('cpu')
有一个.cpu()
方法,与.cuda()
等效,在早期版本中也可用。
It would seem like your GT 425M has the compute capability of 2.1 which does not met the PyTorch required version (at least 3.0) according to @soumith in this thread .
Ergo, it is not possible for you to access some of the GPU-related functions.
You can check the compute capability here
