SyntaxError: invalid syntax 'nn.BatchNorm2d(32)'

SyntaxError: invalid syntax

The syntax error is raised because of the usage of nn.init.kaiming_uniform_() without a comma afterwards.
Remove the nn.init.kaiming_uniform_() call since this is an inplace function on a tensor and it should work.
If you want to initialize parameters of the model, use the model.apply method or call the nn.init methods on parameters directly after creating the object.
