cuda issue

[brad0taylor]

When i run this code

a = torch.Tensor(5, 3) # construct a 5x3 matrix, uninitialized
b = torch.Tensor(5, 3) # construct a 5x3 matrix, uninitialized
if torch.cuda.is_available():
aa= a.cuda()
bb = b.cuda()
aa + bb

I get the following error message
RuntimeError: cuda runtime error (8) : invalid device function at /data/users/soumith/miniconda2/conda-bld/pytorch-0.1.6_1484802121799/work/torch/lib/THC/generated/../generic/THCTensorMathPointwise.cu:246

hey Brad. What GPU are you using?

[brad0taylor]

Hi - I'm using a Geforce GTX950M and I'm using Cuda 8.0. The GPU install works ok with Tensorflow and Theano. Also I have Cudnn installed. I'm fairly new to this, so if you can point me to any diags, I'd be happy to run them. Also the errror message is from the last line of code.

@ngimel I compile the binaries with 5.2+PTX, in that case it should work on 5.0 via JITting right? or is PTX only generated forward (like 5.2+PTX only generates for 5.2+ archs)?

[ngimel]

Jitting works only forward, so probably you should add compilation for 5.0.

[soumith]

oh ok good to know. I'll add 5.0 to the list as well.

@brad0taylor it's a screw up on my end. I'll fix it with issuing new binaries by tomorrow so that you can reinstall and it'll work. If you want to try things right away, please install via source: https://github.com/pytorch/pytorch/blob/master/README.md#from-source

[brad0taylor]

@soumith thanks very much. I'll try again tomorrow

has been fixed
