Invalid device function error when running cumsum on GPU

1

Hi,

I was running the following code on GPU:

import torch
X = torch.rand(4, 4)
X = X.cuda()
torch.cumsum(X, dim=0)

and I got this error:

THCudaCheck FAIL file=/home/shuoyangd/pytorch/torch/lib/THC/generic/THCTensorMathScan.cu line=52 error=8 : invalid device function

What confuses me is that other functionalities (matrix multiplication etc.) seem to work fine (on the same GPU). So just to confirm, is this just that torch.cumsum function does not have GPU support yet?

BTW, I’m using Tesla K80.

Thanks!

Never mind – Guess this is just a device issue. Recompiling solves the problem.
