error in videos/seq2seq/train.py

[alexandrovsky]

Hi, when I run train.py, I get the following error:

Traceback (most recent call last): File "wandb-tutorials/ml-class/videos/seq2seq/train.py", line 131, in <module> guess = ctable.decode(preds[0], calc_argmax=False) File "wandb-tutorials/ml-class/videos/seq2seq/train.py", line 41, in decode return ''.join(self.indices_char[x] for x in x) File "wandb-tutorials/ml-class/videos/seq2seq/train.py", line 41, in <genexpr> return ''.join(self.indices_char[x] for x in x) TypeError: unhashable type: 'numpy.ndarray'

Any ideas how to fix this?
