The super().__init__ call is raising this issue:
super(myConv2D, self).__init__(
    in_channels, out_channels, kernel_size_, stride_, padding_, dilation_,
    False, _pair(0), groups, bias, padding_mode)

since you are passing all arguments to it (while nn.Module is the parent class).
If you want to pass these conv layer arguments to the parent class, you would need to derive myConv2d from nn.Conv2d.
