hi i am working on lstm -CRF for NER .I got the error because of keras version. i am currently using keras 2.3 with tensorflow 2.0


first i was getting this error :
TypeError: Tensors in list passed to 'values' of 'ConcatV2' Op have types [bool, float32] that don't all match.
After installing pip install keras==2.2.4

it gives me : super(type, obj): obj must be an instance or subtype of type
