Hi when I tried to run the upgraded version of the package, for DNN, RNN, GRU,LSTM, all have the error that name 'sequential' is not defined. I use Keras 2.4.3, and tensorflow2.3 Any ideas about why this happened? Thanks!!

I'm sorry - I updated everything to be compatible up until Keras 2.3.1 (which was what you previously mentioned you were using).

I need to update our package further to be compatible with even new versions of Keras/TF. I'll hopefully get to that soon.

Hi the same error popped out in keras 2.3.1...

Hmm, I'm not sure. It is working for me now on keras 2.4.3 and TF 2.3.

If you are getting the error that Sequential is not defined, that might happen because somehow it is not recognizing that Keras is installed. When you import the decoders, do you get the message "Warning: Keras package is not installed..." ?

Nevermind, Thank you so much!! The warning did pop out, but after I fixed this, a new error pop out : module 'tensorflow.python.framework.ops' has no attribute '_TensorLike' Then, I upgraded keras to 2.4.3 with TF 2.3, then everything works now. It seems that for TF2.3, keras has to be at a higher than 2.3.1 version (I use 2.4.3 as you have tested before)...

Glad it's working!
