Error : object of type 'NoneType' has no len()

[ankitbbisht]

i have used the code exactly as written, changed the TRAIN_DATA, used your ner annotator to get the data but still the error thrown as soon as train_spacy function is called.
it's returning null I guess hence the error. Please help.

Tell me the which line thrown the error.
Check if any json is empty, delete the json from list

thanks for quick response, i made a small error while putting in train_data. However i came across one more issue, when i am training the data, iterations are quite up and down. how can i call the best iterated model ?
