SRGAN: ValueError: Input 0 of layer fc1 is incompatible with the layer: expected axis -1 of input shape to have value 25088 but received input with shape [None, 32768]

[protoneqt]

When I run srgan.py, I have the following error:

WARNING:tensorflow:Model was constructed with shape (None, 224, 224, 3) for input Tensor("input_1:0", shape=(None, 224, 224, 3), dtype=float32), but it was called on an input with incompatible shape (None, 256, 256, 3).

Well, I met the same issue with you. I thought it was caused by incompatible versions of Keras & Tensorflow. I used to use the latest version of tensorflow on macOS, the same error message came out.

I reinstalled Keras==2.0.6 & Tensorflow==1.15.0, it works fine now.

Hope it could help you.
