TypeError: Descriptors cannot be created directly. If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0. If you cannot immediately regenerate your protos, some other possible workarounds are: 1. Downgrade the protobuf package to 3.20.x or lower. 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

报错代码

粉丝群一个小伙伴想要安装一个PPOCRLabel，pip里已经把paddlepaddle和paddleorc下好了，然后输入PPOCRLabel --lang ch
，但是还是发生了报错（当时他心里瞬间凉了一大截，跑来找我求助，然后顺利帮助他解决了，顺便记录一下希望可以帮助到更多遇到这个bug不会解决的小伙伴），报错代码如下：

报错信息内容如下：

TypeError: Descriptors cannot not be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.1.0If you cannot immediately regenerate your protos, some other possible workarounds are:
1. Downgrade the protobuf package to 3.20.x or lower.
2. Set PROTOCOL_BUPFERS_PYTHON_iMPLEMENTATION=python (but this will use pure-Python parsing and will be mch slower ,More information: https://developers. google.com/protocol-buffers/docs/news/2022-05-06#python-updates

报错翻译

报错信息翻译如下：

类型错误:无法直接创建描述符。
如果此调用来自_pb2.py文件，则生成的代码已过期，必须使用protoc>=3.1.0重新生成。如果无法立即重新生成protos，则其他一些可能的解决方法如下：

• 将protobuf包降级至3.20.x或更低。
• 设置PROTOCOL_BUPFERS_PYTHON_iMPLEMENTATION=PYTHON（但这将使用纯PYTHON解析，速度会慢很多，更多信息：https://developers.google.com/protocolbuffers/docs/news/2022-05-06#python更新（桨板）F:\pycharm\pycharm社区版2022.1.4\bin\PidleOCR-release-2.6\PPOCRabe1>

报错原因

报错原因：

仔细阅读报错信息就会发现，报错的主要原因是因为protobuf的版本太高而导致编译错误，所以我们只需要按照编译器提示的信息下载3.19.0对应的版本即可解决问题。小伙伴按下面的代码安装指定版本即可！！！

解决方法

执行下面的pip安装命令即可：

pip install protobuf==3.19.0

 

 
1

或者：

pip install 'protobuf~=3.19.0'
