When I use the IMDB dataset I use TEXT,LABEL fields to specify how to tokenize and preprocess the data. Then i build vocab and i can choose min_freq and max_size.
How can i do all of the above when using YelpReviewPolarity for example?
Looking at the code and tutorial it seems i cannot change the tokenizer.
Also, how can i use BucketIterator with YelpReviewPolarity dataset?
