How to fix this error message? tensors = pywrap_tfe.TFE_Py_Execute(ctx._handle, device_name, op_name - graph

Question

The below code is giving an error message. How do I fix this? Says Graph Execution Error. Facial Emotion detection problem.
history = model3.fit(x= train_set, validation_data = validation_set, batch_size = 32, epochs = 20)
provides the error message. How to fix this?

Answer 1

install tensorflow version 2.7 it should work for you , I got same problem and got the solution by installing and using tensorflow version 2.7.
install process:
pip install tensorflow==2.7
in collab :
!pip install tensorflow==2.7

Answer 2

initially I had the same error described above, I installed version 2.7 but now this error is appearing:
