keras backend

[yangyang2000]

keras version 2.4.3
tf version 2.4.1
AttributeError: module 'keras.backend' has no attribute 'logsumexp'

K.logsumexp is no longer in keras.backend? runs when i replace with K.log(K.sum(K.exp...), axis =-1)) though other issues arise.

Yes, annoyingly Keras 2.4 is not backwards compatible with Keras 2.3, which is why our current dependencies are:

    keras < 2.4
    tensorflow > 1.10, < 2.3

See also #352, which will be fixed once #389 is completed.

I see, thanks!
