百度AI与人脸识别：aip-python-sdk-2.2.15

安装使用Python SDK有如下方式：

• 如果已安装pip，执行pip install baidu-aip即可。
• 如果已安装setuptools，执行python setup.py install即可。

修改百度人脸识别SDK错误
[Python]json 错误xx is not JSON serializable

cd至sdk目录aip下：找到face.py文件修改：

'''尾部添加'''
class DateEncoder(json.JSONEncoder):
    def default(self, obj):
        if isinstance(obj, bytes):
            return str(obj, encoding='utf-8')
        return json.JSONEncoder.default(self, obj)

替换所有：json.dumps(images, ensure_ascii=False,cls=DateEncoder)
