I have a network, whose inputs are 2 tensors, like:
def forward(self, inp, rgb):
     #  
    return model

the inp and rgb have different size(both 4D)
while I run model.forward(x1, x1), it went wrong:

    if input is not None and input.dim() != 4:
AttributeError: 'list' object has no attribute 'dim'


is that the input of module must have be one argument?
thx
