getting incompability of protobuf while install grpcio-tools

when I want to install grpcio-tools using command :

python3 -m pip install grpcio-tools

[![enter image description here][1]][1]

while on the other hand when I want to run pip3 install mysql-connector-python to install mysql-connector-python: [![enter image description here][2]][2]

what should I do for this incompability?

whereis protoc
protoc: /usr/local/bin/protoc


 pip show protobuf
 Name: protobuf
 Version: 3.20.1
 Summary: Protocol Buffers
 Home-page: https://developers.google.com/protocol-buffers/
 Author: None
 Author-email: None
 License: BSD-3-Clause
 Location: /home/lfathi/.local/lib/python3.8/site-packages
 Requires: 
 Required-by: mysql-connector-python, grpcio-tools

protoc --version
 libprotoc 3.2.0

which causes problem in running grpc [1]: https://i.sstatic.net/NZ15N.png [2]: https://i.sstatic.net/LXpM1.png

I had the same error trying to build a container image. It errored at RUN pip install -r requirements.txt with the below:

ERROR: Cannot install grpcio-status==1.53.0, mysql-connector-python==8.0.32 and protobuf==4.22.1 
because these package versions have conflicting dependencies

    grpcio-status 1.53.0 depends on protobuf>=4.21.6
    mysql-connector-python 8.0.32 depends on protobuf<=3.20.3 and >=3.11.0

    To fix this you could try to:
    1. loosen the range of package versions you have specified
    2. remove package versions to allow pip attempt to solve the dependency conflict

Removing the package version (as in suggested fix 2) solved the problem for me.

  • requirements.txt (dependencies with package versions):
grpcio-status==1.53.0
mysql-connector-python==8.0.32
protobuf==4.22.1
  • I solved the problem by removing the package versions:
grpcio-status
mysql-connector-python
protobuf

Alternatively, install the packages together as below. Pip will attempt to solve the conflict:

pip install mysql-connector-python grpcio-tools protobuf

mysql-connector-python does appear to require protobuf:

python3 -m venv venv
source venv/bin/activate
python3 -m pip install mysql-connector-python==8.0.31
python3 -m pip freeze

Yields:

mysql-connector-python==8.0.31
protobuf==3.20.1

Or /path/to/venv/lib/python3.9/site-packages/mysql_connector_python-8.0.31.dist-info/METADATA

Google made breaking changes to the Python implementation of Protocol Buffers between 3.20.1 and 4.20.1.

You need to find a grpcio-tools release that uses <=3.20.1. Curiously, 1.46.0 should work (03-May-2022) as it's beween protobuf 3.20.1 (21-Apr-2022) and 3.20.2 (13-Sep-2022) but, this also fails.

Please try:

python3 -m pip install mysql-connector-python==8.0.31
python3 -m pip install grpcio-tools==1.44.0

python3 -m pip freeze

Yields:

grpcio==1.51.1
grpcio-tools==1.44.0
mysql-connector-python==8.0.31
protobuf==3.20.3
