请问如何在一个graph内设置两个输出？

[QQiangren]

运行人脸识别demo（trt_face_detect.py）把判断语句：if (output_queue_size >= 2):屏蔽掉，云溪谷会报错：

是否是graph内只设置了一个输出，但是trt_face_detect.py内逻辑输出了文本的输出。请问在graph内怎样设置才能正确输出两个结果。

我的graph代码如下：
import time
import tensorrt as trt
import bmf.hml.hmp as mp
from nms import NMS
import PIL
from PIL import Image

def main():
graph1 = graph({'dump_graph':1})

video = graph1.decode({
    "input_path": "./face.mp4",
    "video_params": {
       "hwaccel": "cuda",
    }
})["video"]

video = video.module("trt_face_detect", {
    "model_path": "./version-RFB-640.engine",
    "input_shapes": {
        "input": [1, 3, 480, 640]
    }}, entry="trt_face_detect_ok.trt_face_detect")

video = video.module("face_postprocess",
    entry="face_postprocess.face_postprocess")

video = video.encode(
    None, {
        "output_path": "./trt_out.mp4",
        "video_params": {
            "codec": "h264_nvenc",
            "bit_rate": 5000000,
            "max_fr": 30
        }
    }
    )


video.run()

if name == "main":
main()
感谢！

video = module("TWO_OUTPUT"...)
stream1 = video.module(...)
stream2 = video.module(...)
