The above exception was the direct cause of the following exception:

what is your tensorflow, keras version?

[binghong-ml]

Thanks for noting this! It's Keras 2.4.3.

I got the same error. @binghong-ml Would you let me know your tensorflow version? FYI, I tried tensorflow version 2.5.0.

i solved the problem by this op: keras-team/keras#14632

[binghong-ml]

Could you try Tensorflow-cpu 2.3?

Thanks @nickyoungforu , it solves the problem!

It gives another error as follows:
