Error occurs in out-loop backward #18

Open dieuroi opened 3 years ago

dieuroi commented 3 years ago

RuntimeError: one of the variables needed for gradient computation has been modified by an inplace operation

I think the backward operation in train_one_batch (line 308 in transformer.py) has freed the graph, while this does not disturb the out-loop backward.

The error occurs when batch_loss.backward() (line 167 in MAML.py)
