could you tell me what version shoud use ?

Keras.backend doesnt have slice operation. Instead you can go to the location where crf.py file is stored locally on your machine (this you can find mentioned in the error dialogue, i.e. /home//anaconda3/lib/python3.8/site-packages/keras_contrib/layers/crf.py) and do the following:

add the line --> import tensrflow as tf goto line where it is mentioned K.slice --> you can do a search for "slice" --> replace K.slice by tf.slice

restart the jupyter notebook session. This should work.

Yea, that works. Thanks !
