AttributeError: module 'matplotlib' has no attribute 'get_data_path' on Visual Studio's jupyter-notebook

Question

I get the following error when I want to import matplotlib.pyplot on the Visual Studio's jupyter-notebook.

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
 in 
----> 1 import matplotlib.pyplot as plt

~/miniconda3/envs/firstSteps/lib/python3.8/site-packages/matplotlib/__init__.py in 
    903 # triggering resolution of _auto_backend_sentinel.
    904 rcParamsDefault = _rc_params_in_file(
--> 905     cbook._get_data_path("matplotlibrc"),
    906     # Strip leading comment.
    907     transform=lambda line: line[1:] if line.startswith("#") else line,

~/.local/lib/python3.8/site-packages/matplotlib/cbook/__init__.py in _get_data_path(*args)

AttributeError: module 'matplotlib' has no attribute 'get_data_path'

But I don't have this error if I try the same code on the navigator's jupyter-notebook. So I don't understand why I get this error since both notebook are running under the same kernel which have the matplotlib 3.3.1 version installed on.

I would be grateful if someone can give me any enlightenment. :)

Solution

I had this same problem and solve it by using the following sequence \

• use terminal to direct to project root folder
• Suppose you are running conda environment. so, activate the environment by
  conda activate env-name
• run python interpreter : python command and check weather matplotib has installed by\
  import matplotlib
• run code . command to open VScode in this directory.
• open terminal and check weather enviromnet has activated
• also check weather jupyter Ipython kernel runs on the same environment
• if any environment is not the one then, change it to a particular one\

this won't happen in the pip environment usually, because VScode does not activate two channels [pip, conda] or conda environment automatically most of the times.

I know, but I do not have a reputation to comment, and it might provide some insight as I found this question because I had the same problem and solved it this way.

If you could explain a bit more it might be more helpful

I had that error when using a kernel, which was not up-to-date (but in which I had already used matplotlib a few months/a year ago). When I used one that it was up-to-date, the problem disappear. (This is not an actual solution, but it solved the problem for me and may be an hint for someone else).
