The input must have 3 channels, I need 1 channel

[MohannadEhabBarakat]

When running following code
base_model = efn.EfficientNetB0(include_top=False, weights='imagenet', input_shape=(256,256,1))
I get
Traceback (most recent call last):
File "models/discriminator.py", line 40, in

You can add a convolutional layer with feature maps 3 with pad size 3 (same) to match with the imagenet weights.

This issue is not related to the package itself, so I suggest to close it.
