error when checking target

[shardul2903]

i) in your model.py
input_size (256,256,1) => (256,256,3)
ii) trainGenerator function in your data.py
image_color_mode ="grayscale"=>"rgb"
iii) testGenerator function in your data.py
comment out "img = np.reshape(img,img.shape+(1,)) if (not flag_multi_class) else img"

I followed the above steps but I get the following error:
ValueError: Error when checking target: expected conv2d_24 to have shape (256, 256, 1) but got array with shape (256, 256, 3)

In data.py we have in testGenerator
img = np.reshape(img,img.shape+(1,)) if (not flag_multi_class) else img
you have change it to
img = np.reshape(img,img.shape+(3,)) if (not flag_multi_class) else img
This will solve the issue
