Matplotlib - AttributeError: 'version_info' object has no attribute 'version"

Question

I am not sure how to fix this error. I have tried searching everywhere. This error only comes up when I try to interact with matplotlib. My pip is fully upgraded and I am using python 3.6.0 for a class. Thank you!

Python 3.6.0 (v3.6.0:41df79263a11, Dec 23 2016, 07:18:10) [MSC v.1900 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information.

import matplotlib Traceback (most recent call last): File "", line 1, in File "C:\Users\syner\AppData\Local\Programs\Python\Python36-32\lib\site-packages\matplotlib_init_.py", line 107, in from . import cbook, rcsetup File "C:\Users\syner\AppData\Local\Programs\Python\Python36-32\lib\site-packages\matplotlib\rcsetup.py", line 28, in from matplotlib.fontconfig_pattern import parse_fontconfig_pattern File "C:\Users\syner\AppData\Local\Programs\Python\Python36-32\lib\site-packages\matplotlib\fontconfig_pattern.py", line 15, in from pyparsing import (Literal, ZeroOrMore, Optional, Regex, StringEnd, File "C:\Users\syner\AppData\Local\Programs\Python\Python36-32\lib\site-packages\pyparsing_init_.py", line 130, in version = version_info.version AttributeError: 'version_info' object has no attribute 'version'

Try this:import matplotlib;print('matplotlib: {}'.format(matplotlib.__version__)) — r-beginners

Thank you for your comment. It still gives the same error and does not print a version. — Capsaisyn

However, when I run 'pip show matplotlib' in the cmd window, it shows 3.3.4 — Capsaisyn

I figured out the solution for my problem. I noticed that just before the AttributeError, it is trying to import pyparsing, so I looked for solutions for that. I stumbled upon a stackoverflow post: unknown version in python library pyparsing

The answer of installing version 2.4.7 worked for me. Since I am running 2016 software in 2021, I think the newest version was creating problems.

Thank you!

I had the same issue and found this solution

unknown version in python library pyparsing

It is not Matplotlib that is the problem. It is pyparsing

"Try manually installing pyparsing 2.4.7 using "pip install pyparsing==2.4.7". There are some versioning issues being sorted out, so using the last stable pyparsing version should be of some help."

I installed this pyparsing version and now import matplotlib works.
