Hi 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?
