@lminer, I'm using fastai version 1.0.50 and ``` hl.build_graph(learn.model, torch.zeros([1, 3, 224, 224]).cuda()) ``` works fine. Can you confirm which version you're using?

I was facing the same issue, even with the latest build. Although it looks like it's stuck at the "writing output" stage, it's actually stuck at the next poisson surface...
