Valueerror: Input 0 Of Layer Sequential Is Incompatible With The Layer: Expected Axis -1 Of Input Shape To Have Value 1

Title : ValueError: Input 0 of layer sequential is incompatible with the layer: expected axis -1 of input shape to have value 1 but received input with shape [None, None, None, 3]

Solution 1:

Issue is with this line

model.add(Conv2D(NUMB_FILTER_L1, (5, 5), 
             input_shape=input_shape_val, 
             padding='same', name='input_tensor'))

If your dataset is of RGB images, input_shape should have 3 channels something like

input_shape =(img_width, img_height, 3)

If in case Grayscale image, use channel value as 1
