如何解决“ AttributeError: 模块‘ google.Protobuf.description’没有属性‘_Internal_create_key’”？

我在木星笔记本中执行 from object_detection.utils import label_map_util时遇到了它。它实际上是张量流目标检测教程笔记本(附带张量流目标检测应用程序接口) 完整的错误日志:

The protoc version I got through pip show protobuf and protoc --version were different. The version in pip was a bit outdated.

After I upgraded the pip version with

pip install --upgrade protobuf

the problem was solved.

These three commands solved it for me:

pip uninstall protobuf python3-protobuf
pip install --upgrade pip
pip install --upgrade protobuf

After trying many different solutions (i'm working on a Mac) the one that worked for me is to reinstall protobuf using:

PROTOC_ZIP=protoc-3.7.1-osx-x86_64.zip
curl -OL https://github.com/protocolbuffers/protobuf/releases/download/v3.7.1/$PROTOC_ZIP
sudo unzip -o $PROTOC_ZIP -d /usr/local bin/protoc
sudo unzip -o $PROTOC_ZIP -d /usr/local 'include/*'
rm -f $PROTOC_ZIP

As is highlighted in this article

For others looking into this more recently newer google libraries are using proto plus, a wrapper for python proto messages. Using this helper function worked for me (cred: tobked)

import json


import proto


def proto_message_to_dict(message: proto.Message) -> dict:
"""Helper method to parse protobuf message to dictionary."""
return json.loads(message.__class__.to_json(message))

the problem for me was i had libprotobuf at 3.11 and protobuf at 3.15 upgrading libprotobuf fixed it for me.

This can be due to incorrect versions of protobuf and python3-protobuf in your IDE(in my case PyCharm) and in site-packages. Following solved error in my case:

pip uninstall python3-protobuf
pip uninstall protobuf

then finally do

pip install protobuf

Also if you have requirements.txt or setup.py check protobuf version from pip freeze and use the same version in your requirements.txt file

pip freeze

(check protobuf version, and use same in requirements.txt)

protobuf==3.15.6 (in my case pip freeze gave me this version for protobuf)

I got this problem in Anaconda too. I installed it with:

conda install -c conda-forge streamlit

with the versions protobuf and libprotobuf of 3.11.4

I was not able to update neither protobuf nor libprotobuf.

I recommend to install first "conda install protobuf" and then

conda install -c conda-forge streamlit

I got now the versions protobuf and libprotobuf of 3.14.0 and it works.

This can also happen if you use protoc to generate your language specific bindings file in a different OS than where you import it. For example,

Linux OS

protoc -I=./ --python_out=./ my_module.proto

Mac OS

import my_module_pb2

The issue of my condition is protoc not install.

step to solve the problem:

  1. check pip3 show protobuf, you will see version of protobuf.
    • e.q. Version: 3.17.3
  2. goto protobuf release page and install same version of protoc
      1. wget https://github.com/protocolbuffers/protobuf/releases/download/v3.17.3/protoc-3.17.3-linux-x86_64.zip
      2. unzip protoc-3.17.3-linux-x86_64.zip
      3. vim ~/.bashprofile and paste PATH=$PATH:/home/YOUR_HOST_NAME/bin
      4. source ~/.bashprofile and echo $PATH to check whether /home/YOUR_HOST_NAME/bin exist or not.
  3. check pip3 show protobuf is equal to protoc --version
  4. If not work, reboot and try again.

Downgrade protobuf using pip

Sometimes the upgrade code pip install --upgrade protobuf throwed another error. -

  • version 3.20 seems to be working properly
pip install protobuf==3.20.*

similar to TypeError: Descriptors cannot not be created directly
