interface.py中第一个会报错，不知道怎么解决 !

我理解的是，没有编译 PADDLE_WITH_DISTRIBUTED 环境，导致 dist_attr 为 None：

Paddle/paddle/fluid/pybind/eager_properties.cc

Lines 375 to 389 in e084133

	PyObject* tensor_properties_get_dist_attr(TensorObject* self, void* closure) {
	EAGER_TRY
	if (self->tensor.is_dist_tensor()) {
	#ifdef PADDLE_WITH_DISTRIBUTE
	phi::distributed::DistTensor* dist_tensor =
	static_cast<phi::distributed::DistTensor*>(self->tensor.impl().get());
	return ToPyObject(&dist_tensor->dist_attr());
	#else
	RETURN_PY_NONE
	#endif
	} else {
	RETURN_PY_NONE
	}
	EAGER_CATCH_AND_THROW_RETURN_NULL
	}

@SigureMo 先把整段测试代码加个 # doctest: +REQUIRES(env:DISTRIBUTED) ？
