AttributeError: 'dict_values' has no attribute 'index'

[demetrii]

Upon running for s in sources: source, predicted = predictor.predict(s) print('\n---SOURCE----\n' + source) print('---PREDICTED----\n' + predicted)

I get the following error:
INFO:tensorflow:Restoring parameters from /content/lab/datalab/punctuation/model/punctuation-5796

AttributeError: 'dict_values' object has no attribute 'index'

This is how index is defined:
words1 = [self._word_to_id.keys()[self._word_to_id.values().index(data_x[index])] for index in range(len(puncts) - 1)]

indices = [i for i, w in enumerate(words1) if w in PUNCTUATIONS]

for i in indices:

words1[i], words1[i-1] = words1[i-1], words1[i] #only line in for loop

words2 = [self._word_to_id.keys()[self._word_to_id.values().index(data_x[index])] for index in range(len(puncts) - 1, len(data_x))]
all_words = words1 + [puncts[-1]] + words2
content = ' '.join(all_words)
min_step = len(puncts)

Can anyone explain why this occurs and/or how to fix this?

[demetrii]

This error is because the .index() method is supported by Python 2, but unsupported by Python 3. I am currently trying to find a way around. Feel free to share (potential) solutions

[demetrii]

Rewrote:
[self._word_to_id.keys()[self._word_to_id.values().index(data_x[index])] for index in range(len(puncts) - 1, len(data_x))]
to the following:
[self._word_to_id.keys()[list(self._word_to_id.values()).index(data_x[index])] for index in range(len(puncts) - 1, len(data_x))]
However, the error that I get is 'dict_keys' object does not support indexing. Any suggested solution?

[shubham8garg]

Did you try this:-
[list(self._word_to_id.keys())[list(self._word_to_id.values()).index(data_x[index])]

I guess this can unblock you.
