RuntimeError in prediction task

[arhouati]

Hello,

While trying to execute the prediction task, I have the following Error :
RuntimeError: Only Tensors created explicitly by the user (graph leaves) support the deepcopy protocol at the moment

The error is caused by this line of code : "predictions.append(model.predict(batch, opt, None))" (line : 57 / translate.py)

Did you get the same error in some steps?
How could I fix this issue?

Thanks in advance,
Best Regards.
