Description
请提出你的问题 Please ask your question
paddle 目前的 place 是一个 python 端全局的对象。
https://github.com/PaddlePaddle/Paddle/blob/develop/python/paddle/fluid/framework.py#L517-L520
def _set_expected_place(place):
global _global_expected_place_
_global_expected_place_ = place
_set_dygraph_tracer_expected_place(place)
int GetCurrentDeviceId() {
int device_id;
PADDLE_ENFORCE_GPU_SUCCESS(cudaGetDevice(&device_id));
return device_id;
}
中的 GetCurrentDeviceId 是不是完全没有关联。
C++中如何获取当前place的 device id.
