导入错误：无法从“google.protobuf.pyext”导入名称“_message”（c:\programdata\anaconda3\lib\site-packages\google\protobuf\pyext\__init__.py）

Question

我正在尝试这个命令（我不知道它做了什么：我只遵循教程）：

tensorboard --logdir=/tmp/tensorflow/rnn_words

并得到这个结果：

Traceback (most recent call last):
  File "c:\programdata\anaconda3\lib\runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)

    from google.protobuf.pyext import _message
ImportError: cannot import name '_message' from 'google.protobuf.pyext' (c:\programdata\anaconda3\lib\site-packages\google\protobuf\pyext\__init__.py)

上面的命令是做什么的？ 为什么我会收到此错误消息？

C:\Windows\system32>python --version
Python 3.7.1

C:\Windows\system32>pip install protobuf
Requirement already satisfied: protobuf in c:\programdata\anaconda3\lib\site-packages (3.6.1)
Requirement already satisfied: six>=1.9 in c:\programdata\anaconda3\lib\site-packages (from protobuf) (1.12.0)
Requirement already satisfied: setuptools in c:\programdata\anaconda3\lib\site-packages (from protobuf) (40.6.3)

Answer 1

如果你在 mac，请尝试 pip install --upgrade --force-reinstall protobuf

Answer 2

适用于pip install protobuf==3.14.0和 Python 3.9

您可以使用以下方法进行测试：

# python
Python 3.9.13 (main, Aug  2 2022, 11:20:39)
>>> from google.protobuf.pyext.cpp_message import GeneratedProtocolMessageType

Answer 3

请使用以下命令升级protobuf ：

pip3 install --upgrade --force-reinstall protobuf==4.32.2

Answer 4

对我来说，我降级了 protobuf pip install protobuf==3.19.6

Answer 5

根据tensorboard issue #1556的解决方案，您应该也可以通过升级到 tensorboard==1.13.0（或更高版本）来解决您的问题。

IMO，这是最干净的解决方案。
