读.yml文件时出现UnicodeDecodeError: ‘ascii‘ codec can‘t decode byte 0xe5 in position问题

训练模型的时候，要读取.yml文件结果出现了这种错误，
把

    with open(opt_path, mode='r') as f:
        opt = yaml.load(f, Loader=Loader)

改成

    with open(opt_path, mode='r',encoding='utf-8') as f:
        opt = yaml.load(f, Loader=Loader)

就可以了。
