AssertionError: Torch not compiled with CUDA enabled

[azureskyL]

when I run

python train.py -data data/multi30k.atok.low.train.pt -save_model multi30k_model -gpus 0

An error occurs, Could anyone help me?

Did you install PyTorch with CUDA support? If not, you should not use the -gpus option.

the problem also arises when translating with one of the provided models (I tried with onmt_model_en_fr_b1M). Setting -gpu -1 doesn't help.

the following workaround worked in my case: substitute this line with this one checkpoint = torch.load(opt.model, map_location=lambda storage, loc: storage)
