The same problem occurs with me while using keras with CNN-LSTM. The code was working fine on GPU server, but when I tried to run it on my local machine, got this weird error.

The following trick works for me.

Solution: clear variables and restart your kernel. This work for me. Maybe someone else getting to exactly the same problem what I am going through will be helpful.
