类似 AttributeError 的错误，如果是示例本身有问题的话，需要尽量修改正确 ～
如果是依赖环境的问题，如 distributed，可以用 REQUIRES ～
如果还是不行，如依赖外部文件等，再用 skip ～
这段示例中，AttributeError 是 SGD 导致的，即便不是 distributed 环境也会出错，所以，需要先修改 SGD 正确：
>>> import paddle
>>> import paddle.distributed.fleet as fleet
>>> fleet.init(is_collective=True)
>>> strategy = fleet.DistributedStrategy()
>>> linear = paddle.nn.Linear(10, 10)
>>> optimizer = paddle.optimizer.SGD(learning_rate=0.001, parameters=linear.parameters())
>>> optimizer = fleet.optimizer.distributed_optimizer(optimizer, strategy=strategy)
