The error is caused by the fact that the ResNet class constructor requires two arguments block and layers, which are not provided when creating an instance of the class. To fix the error, you need to provide these arguments when creating an instance of the ResNet class. For example:

network = ResNet(BasicBlock, [2, 2, 2, 2])

This creates an instance of the ResNet class with BasicBlock as the block type and [2, 2, 2, 2] as the number of layers for each block in the ResNet. Adjust the values of these arguments based on your specific needs.
