matplotlib Ver 3.3.3 from Python Shell - <solved>

I'm having problems using Matplotlib on Linux Mint 20 (Ubuntu 20.04) from the python Shell

Traceback (most recent call last): Python Shell, prompt 1, line 967

builtins.AttributeError: partially initialized module 'matplotlib' has no attribute '__path__' (most likely due to a circular import)

During handling of the above exception, another exception was raised:

Traceback (most recent call last):

I'm able to run a simple example on ubuntu 20.10 with the system provided python & matplotlib and also matplotlib 3.3.3 installed via pip. What versions of Wing and python are you using? Also what code are you running in the Python Shell?

I'm running Python 3.8.5 and WingPro 7.2.7.0

'import matplotlib' is the only command in the Python Shell.

The problem is comparatively minor as I am using scripts for almost all my work. The question was started before I realised that scripts worked OK.

Could you send the full traceback and exception to support@wingware.com?

Problem Solved. There was a file "matplotlib.py" in the current folder dating back to 2018 ! (the last time I played with matplotlib) which contained the line "import matplotlib.pyplot as plt"

Apologies - I should have examined the error message more carefully before suspecting other peoples software !

During handling of the above exception, another exception was raised: Traceback (most recent call last): Python Shell, prompt 1, line 1 # Used internally for debug sandbox under external interpreter
File "/home/**/winglets/matplotlib.py", line 8, in <module> import matplotlib.pyplot as plt builtins.ModuleNotFoundError: No module named' matplotlib.pyplot'; 'matplotlib' is not a package
