can't train on custom data

[k-maheshkumar]

Thanks for the implementation. I am trying to train on custom data. But I am getting following error. Could you please help me to resolve this issue.

WARNING:tensorflow:Model was constructed with shape (None, 13, 13, 3, 6) for input Tensor("input_4:0", shape=(None, 13, 13, 3, 6), dtype=float32), but it was called on an input with incompatible shape (13, 13, 3, 6).
