AttributeError: 'StyTrans' object has no attribute 'module'

这个错误通常在使用 PyTorch 的多 GPU 训练时出现。在多 GPU 训练中，模型通常会被包装在 nn.DataParallel 或 nn.parallel.DistributedDataParallel 中，以实现并行计算。这会导致模型对象的属性访问发生变化。

解决方法

optimizer = torch.optim.Adam([ {'params': network.module.transformer.parameters()},{'params': network.module.decode.parameters()},{'params': network.module.embedding.parameters()},], lr=args.lr)

optimizer = torch.optim.Adam([ {'params': network.transformer.parameters()},{'params': network.decode.parameters()},{'params': network.embedding.parameters()},], lr=args.lr)
