Should be propagated, no?

[sonali-kumari1]

Hi @fchollet, When i am using output_padding=0 in keras(3.8.0), I am getting ValueError: The output_padding argument must be a tuple of 1 integers. Received output_padding=0, including values {0} that do not satisfy value > 0 but setting output_padding=None, it works without error. So, should I modify the error message to raise AttributeError or remove this argument ?
