一、自己训练模型
二、调用现成API
此处介绍百度智能云API，因为有免费次数。（原来一些网址在百度不是默认显示网址的，而是自己的网站名字）
首页找到OCR
每个人每月能用1K次。（有详细的API文档说明，不过跟着我的步骤来也足够）
在创建应用后得到API key和 Secret Key
还需要拿到一个access token
#官方代码

import jsondef main():url = "https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id=xxxxxx&client_secret=xxxxx"payload = ""headers = {'Content-Type': 'application/json','Accept': 'application/json'}response = requests.request("POST", url, headers=headers, data=payload)print(response.text)if __name__ == '__main__':main()# 更改为个人使用版本
