请问这个问题该如何解决呢？这是对应的代码， class _LegacyUnpickler(pickle.Unpickler): def find_class(self, module, name): if module == 'dnnlib.tflib.network' and name == 'Network': return _TFNetworkStub if module == 'torch.storage' and name == '_load_from_bytes': return lambda b: torch.load(io.BytesIO(b), map_location='cpu') return super().find_class(module, name)
