/opt/conda/conda-bld/pytorch_1503970438496 which appears in the error doesnt exist in the cluster but how can I fix that?

This is the path where we built pytorch. the binaries just have such paths.
This is super weird that the output of a nn.Sigmoid on the cluster is giving you -0.020724.
Can you post your DCGAN implementation, atleast the part where the DCGAN model definition is?
