Hello I am a beginner in ML. I tried to use BERT and tokenizer didn't work like below.
train_input = bert_encode(train.text.values, tokenizer, max_len=160)
test_input = bert_encode(test.text.values, tokenizer, max_len=160)
train_labels = train.target.values
/usr/local/lib/python3.7/dist-packages/absl/flags/_flagvalues.py in __getattr__(self, name)
496 # get too much noise.
497 logging.error(error_message)
--> 498 raise _exceptions.UnparsedFlagAccessError(error_message)
499
500 def __setattr__(self, name, value):
UnparsedFlagAccessError: Trying to access flag --preserve_unused_tokens before flags were parsed.
