使用tensorbaoardx报错——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 If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.

 

 

运行代码报错：

from tensorboardX import SummaryWriter

 

 

 

 

报错内容：

 

 

 

发生异常: 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 If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.

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).

=================================================

 

 

 

 

根据报错信息提供的链接：

https://developers.google.com/protocol-buffers/docs/news/2022-05-06#python-updates

 

 

根据官方给出的资料，可以知道Google的序列化协议protobuf已经由版本3.20.1升级到4.21.6，一些需要调用旧版本protobuf的python库将出错，这种情况需要通过设置环境变量或者安装旧版本的protobuf来解决。

 

 

查看一下本地的protobuf版本：

pip list

 

显示：

 

 

大概率确定是安装的protobuf版本高了的问题，更新低版本的protobuf，具体操作：

pip install --upgrade protobuf==3.20.1

再次运行，不报错，成功解决。
