1.github:https://github.com/qqwweee/keras-yolo3

　　中文使用教程：https://busy.org/@hongtao/yolo

2. keras中文：https://keras.io/zh/getting-started/sequential-model-guide/

３．通过anonconda3安装keras，tensoflow-gpu环境：https://blog.csdn.net/qq_38901147/article/details/90049666

 

 

报错：
１．运行python yolo_video.py --input

 File "/home/zengjun/Resume/yolo_detection/keras_yolov3/keras-yolo3/yolo.py", line 173, in detect_video
    import cv2
ImportError: /opt/ros/kinetic/lib/python2.7/dist-packages/cv2.so: undefined symbol: PyCObject_Type

原因：https://blog.csdn.net/Changer_sun/article/details/81079756这篇文章讲解了问题背景

环境变量'/opt/ros/kinetic/lib/python2.7/dist-packages'的优先级更高，将其从环境变量删除就不会报错
