I am a beginner in machine learning.
I'm studying machine learning RNN.
history=ins_model.fit(x,t,epochs=20,batch_size=batch_size,validation_split=0.1)
When I added and executed the above code, PyCharm received the following message:
What does this mean?
It seems that model learning is being conducted for the time being.
I would appreciate it if you could tell me how to deal with it.
Thank you for your cooperation.

This is because the graph has a circular dependency.Computational graphs must be linear.Review the code and remove the circular dependencies to make them linear.
