'zip' object is not subscriptable

[al-yakubovich]

I have the same problem as here

I changed line 46 to self.token_to_id = dict((k, self.full_token_to_id[k]) for k in list(self.full_token_to_id.keys())[:max_vocabulary_size])

But still got the error:

     44             full_token_and_id = zip(vocabulary, range(len(vocabulary)))
     45             self.full_token_to_id = dict(full_token_and_id)
---> 46             self.token_to_id = dict((k, self.full_token_to_id[k]) for k in list(self.full_token_to_id.keys())[:max_vocabulary_size])
     47 
     48         self.id_to_token = {v: k for k, v in self.token_to_id.items()}

TypeError: 'zip' object is not subscriptable
