I am getting a syntax error when trying to import matplotlib as plt:

python3 sigClassCNN_tensor.py
Traceback (most recent call last):
  File "sigClassCNN_tensor.py", line 22, in <module>
    import matplotlib.pyplot as plt
  File "/usr/lib64/python3.4/site-packages/matplotlib/__init__.py", line 131, in <module>
    from matplotlib.rcsetup import defaultParams, validate_backend, cycler
  File "/usr/lib64/python3.4/site-packages/matplotlib/rcsetup.py", line 29, in <module>
    from matplotlib.fontconfig_pattern import parse_fontconfig_pattern
  File "/usr/lib64/python3.4/site-packages/matplotlib/fontconfig_pattern.py", line 22, in <module>
    from pyparsing import (Literal, ZeroOrMore, Optional, Regex, StringEnd,
  File "/usr/lib/python2.7/site-packages/pyparsing.py", line 2480
    except ParseException, err:

I had this code working before.

Not sure what's changed.

How can I fix it?

    Looks like it's mixing in python2 files ... Commented May 22, 2018 at 6:00
  • Make sure you have imported and updated all libraries to python3? Commented May 22, 2018 at 6:01
  • Please show a full (including the '#!' if you use one, otherwise the command used to invoke) code that generates this error. Commented May 22, 2018 at 6:04
  • So I have both Python2.7 and Python3.4 on my Centos machine. The code was run using a python3 compiler. From the error message, it looks like pyparsing.py was called using the python2.7 version. why would this be the case? Commented May 24, 2018 at 1:10
  • The original code was really long, include some of tensorflow stuff. But I am certain that it is the matplotlib package that's causing the issue. The code runs without error, if I comment it out. Commented May 24, 2018 at 1:13
