如果遇到权限问题需要使用sudo或su切换root
## 环境配置问题：
未切换环境
conda activate data
没装TensorFlow
pip install tensorflow 装了2.x版本
没装opencv
pip install opencv-python 装了4.x版本
没装pygame
pip install pygame 装了2.x版本
TensorFlow2.x版本过高
pip uninstall tensorflow
conda install tensorflow=1.14.0
Python3.8版本过高（TensorFlow1 不支持 Python3.8，降级Python和安装是一样的，指定版本号即可）
conda install python=3.6
conda install tensorflow=1.14.0
h5py有问题
pip uninstall h5py
参考https://blog.csdn.net/zhanghao_0517/article/details/109630391
