Tensorflow: Cannot interpret feed_dict key as Tensor

This worked for me

from keras import backend as K

and after predicting my data i inserted this part of code
then i had again loaded the model.

K.clear_session()

i faced this problem in production server,
but in my pc it was running fine

………..

from keras import backend as K

#Before prediction
K.clear_session()

#After prediction
K.clear_session()
