Is this a bug?

First, I try to create the model
base_model = create_model(weights="imagenet")
output:

---------------------------------------------------------------------------

    842             continue

    845               f'{symbolic_weights[i].name}. '

ValueError: Shape mismatch in layer #1 (named conv2d_1) for weight conv2d_1/kernel:0. Weight expects shape (3, 3, 32, 32). Received saved weight with shape (32, 3, 3, 3)

After, I run it again without restart runtime.

Then, I run it again. There is no error occur again. Is it suppose to raise an error for shape mismatch or something?
