AttributeError: ‘version_info’ object has no attribute ‘__version__’ when trying to load Yolo Model Weights

by |Published

I have been referred to this platform from Stackoverflow for this question

I am trying to follow this video: https://www.youtube.com/watch?v=_UqmgHKdntU

I cloned the github repository, and then I downloaded the weight files. I also created a virtual environment with python 3.6.0 (because Python 3.9.2 was giving error due to incomaptibility with Tensorflow version 2.2 which was in the requirements.txt file)

However, when I tried to load the weights with the following command,

python load_weights.py

I am getting this error,

__version__ = __version_info__.__version__
AttributeError: 'version_info' object has no attribute '__version__'

I tried to find this a lot on Stackoverflow and other places on Google but could not find anything that worked for me.

The complete error is given below,

File "load_weights.py", line 4, in <module>
    from yolov3_tf2.models import YoloV3, YoloV3Tiny

One of the solutions on Stackoverflow told me to change pyparsing library, https://stackoverflow.com/questions/69964466/unknown-version-in-python-library-pyparsing

I checked the pyparsing version using the command pip show pyparsing, which displayed the following results,

WARNING: Ignoring invalid distribution -ensorflow (e:hassanexample4object-detection-apivenvlibsite-packages)
Name: pyparsing
Version: 3.0.7
Summary: Python parsing module
Home-page: https://github.com/pyparsing/pyparsing/
Author: Paul McGuire
Author-email: ptmcg.gm+pyparsing@gmail.com
License: MIT License
Location: e:example4object-detection-apivenvlibsite-packages
Requires:
Required-by: matplotlib

After which I tried to install the pyparsing version 3.0.7 using the command pip install pyparsing==3.0.7, however I got this message,

Requirement already satisfied: pyparsing==3.0.7 in e:example4object-detection-apivenvlibsite-packages (3.0.7)
WARNING: You are using pip version 21.3.1; however, version 22.0.3 is available.
You should consider upgrading via the 'E:Example4Object-Detection-APIvenvScriptspython.exe -m pip install --upgrade pip' command.

I also tried to uninstall the pyparsing and again install the specified version, but the problem still persisted.

Another solution asked me to also install the tensorflow-gpu which was given on the Github repository,

pip install -r requirements-gpu.txt

I tried this however this also did not work. I also tried to uninstall and install Tensorflow again, but again the same error persisted.

I also tried to upgrade my pip by using this,

python -m pip install --upgrade pip

This showed me the message that,

Requirement already satisfied: pip in e:hassansemester 8researchexample4object-detection-apivenvlibsite-packages (21.3.1)

However, at the end, it said that new version is still available (but it wouldn’t install it, I don’t know for what reason)

WARNING: You are using pip version 21.3.1; however, version 22.0.3 is available.
You should consider upgrading via the 'E:Example4Object-Detection-APIvenvScriptspython.exe -m pip install --upgrade pip' command.

According to one of the posts, upgrading pip solves the problem. I tried to upgrade but it neither upgraded the pip version nor did it solve my problem.

Can anyone help me solve this version error?
