Error when converting gpu model to cpu modle

[lampts]

I'm trying to convert pretrained model on GPU to CPU: th ./tools/release_model.lua -model pretrained/onmt_baseline_wmt15-all.de-en_epoch13_8.98.t7 -output_model pretrained/onmt-wmt15-cpu.t7

I got the following error:

stack traceback:

How to fix that?

[lampts]

I couldn't load this pretrained onmt_baseline_wmt15-all.de-en_epoch13_8.98.t7 on GPU instance as well. Could you help to load it correctly?

[lampts]

I figured out to solve it by adding gpuid 1 for my case.

Thanks for the issue. I'm going to reopen, as we should fail with a more natural error.

Additionally, we should certainly release pre-trained models for the CPU before making them available.
