Every time after training the model when I try to translate I get following error:

python translate.py -model data/norm/model_e3_3656.27.pt -src data/norm/tst.pl -tgt data/norm/tst.en -output data/norm/ep2.en -gpu 2
Traceback (most recent call last):

Please help

The PyTorch version will soon be updated from the folks at pytorch/examples:

Does this particular error happen after training with multiple GPUs?

Thank you for your tip. When I trained using single GPU there was no problem with translation. In that case do you possible plan to repair the problem in near future ?
