Pyplot not installing with matplotlib

I know that this is quite a common problem but when I installed this package I can't seem to get pyplot to be imported with matplotlib. My computer is currently running Pop os and I am using Pycharm as my IDE. When I run anything involved pyplot I get an the console prints out
Traceback (most recent call last):
File "/home/msm/PycharmProjects/Beginner/testing.py", line 1, in <module>
import matplotlib.pyplot as plt
ModuleNotFoundError: No module named 'matplotlib.pyplot'; 'matplotlib' is not a package
I have already tried the following
sudo apt-get install python3-matplotlib in the terminal
Searching for the package within Pycharm
Updating Python
Any help would be greatly appreciated.

try:
pip install matplotlib
if it isn't working try:
pip install --upgrade pip
and try it again
if it isn't working again try start terminal with administrator and add python -m to head of code

ipython no error, jupyter has error ModuleNotFoundError: No module named 'ruamel'

I am running a Python package called pymatgen in Jupyter. Jupyter and pymatgen are installed in a conda environment. I have manually installed ruamel using conda's python3, but the same error occurs. The strange thing is that the same code (in this case just a library load statement) gives no errors when run with ipython. Both Jupyter and ipython are running from the miniconda installation (I check with the command which). I noticed some postings on the web stating that ruamel has problems with conda due to the remapping of a "." to an underscore character, but none of the proposed solutions helped the above problem. I also don't understand why ipython is fine and Jupyter fails. Any suggestions?

Windows VS Code can't find numpy Module even though it is installed (ModuleNotFoundError: No module named 'numpy.core._multiarray_umath')

I have been working with Anaconda and VS Code on my Windows and everything was fine until my computer once crashed. After that, I couldn't run my scripts that worked perfectly fine before.
For example, I now get the the error when running:

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.
We have compiled some common reasons and troubleshooting tips at:
https://numpy.org/devdocs/user/troubleshooting-importerror.html
Please note and check the following:
* The Python version is: Python3.9 from "C:\Users\myname\AppData\Local\Programs\Python\Python39\python.exe"
* The NumPy version is: "1.19.2"
and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.
Original error was: No module named 'numpy.core._multiarray_umath'
I have been reading multiple posts but couldn't find a solution. I tried multiple things:
I have uninstalled and reinstalled anconda
I have added C:\Users\myname\AppData\Local\Programs\Python\Python39 to my system variable path
use pip uninstall numpy and after that conda install numpy
set my python path in VS code to either C:\Users\myname\AppData\Local\Programs\Python\Python39 (pythn verison 3.9.4) or C:\Users\myname\anaconda3 (Python version 3.8.5)
I went to the link mentioned in the error message but couldn't find a solution
tried to upgarde my numpy version (I have 1.20.2)
(pip install numpy --upgrade
Requirement already up-to-date: numpy in c:\users\myname\anaconda3\lib\site-packages (1.20.2))
Python Verison: 3.8.5 and 3.9.4 (tried both)
Numpy Version: 1.20.1
Matplotlib Version: 3.4.1
This
import os
print(sys.version)
print("PYTHONPATH:", os.environ.get('PYTHONPATH'))
print("PATH:", os.environ.get('PATH'))
leads to this output:

Thanks in advance for any help!

You have a lot going on here, including multiple installations of Python. It looks like you have both an Anaconda installation of Python, and a standard Python installation as well.
My first recommendation is to use virtual Python environments. These create isolated environments where you can install packages without worrying about messing up your base installation. There are a handful of ways to do this, Anaconda comes with Conda, and Python comes with venv. Both work well. I prefer Conda.
Step 1 - one or more of the packages in your standard Python installation are corrupted or incompatible; I would recommend uninstalling completely.
-- Windows Key > Settings (Gear icon) > Apps > Click on Python > Uninstall
Step 2 - assuming your Anaconda installation is not also corrupted, we can use Conda to create a new environment.
-- Windows Key > "Anaconda Prompt" > this opens a terminal with the base Anaconda environment.
conda create -n myenv python tensorflow ipython matplotlib pandas seaborn numpy -y
Step 3 - activate the environment to use it and install PyPi packages.
conda activate myenv
pip install pmdarima

Fells like magic, but after applying the steps mentioned by #James, restarting my laptop, disabling and reenabling all extensions in VS Code as well as setting the environment to myenv in Anaconda itself before launching VS Code, it finally works now. Don't know what exactly made the difference though. Thanks again #James for the help!

Error importing seaborn module in Jupyter Notebook

I'm trying to use the seaborn module in jupyter notebook,I alredy installed all the dependecies and the seaborn too,but when I try to run,it's said that it does not have a module seaborn installed
---------------------------------------------------------------------------
ModuleNotFoundError Traceback (most recent call last)
<ipython-input-1-ed806232820c> in <module>
1 import pandas as pd
2 import matplotlib.pyplot as plt
----> 3 import seaborn as sns
ModuleNotFoundError: No module named 'seaborn'

Try restarting notebook first.
Make sure that seaborn is installed by same python interpreter used in the notebook.
Easiest way to be certain of this is to run
!pip install --user seaborn in the active notebook (! allows you to run shell command from your notebook)
Additional info for detecting the cause of the problem
You can check which interpreter is used by the notebook by running:
import sys
print(sys.executable)
I assume pip you used initially is not used by python you used to run the notebook (multiple python installations of the system or conda).
To specify which python is used for pip install you can run
<python-path> -m pip install seaborn where <python-path> is output of sys.executable.

Python - Can't import Seaborn

I'm running iPhyton Notebooks and I'm trying to import the Seaborn package. When I try to import it from the Terminal, it loads up fine, but when I import it through iPython Notebooks, it give me the following error.
I have even tried to re-install Seaborn using both Conda and Pip inside iPython notebooks and still it wont work.
Any idea why?
Thanks.
ImportError Traceback (most recent call last)

ImportError: No module named seaborn

Try this
import sys
print sys.path
sys.path.append('<path to package in your syste>')
import seaborn
In my Ubuntu 14.4LTS the packages get installed in the following folder
/usr/local/lib/python2.7/dist-packages
So I simply add the package path at run time

Donit install Ipython on all your system. Install it only in the environments you want it. Otherwise Ipython will look for modules in the default path instead of the environment's path.
This is probably where your ipython is looking:
/home/user/anaconda2/lib/python2.7/
It should be looking for modules here:
/home/user/anaconda2/envs/name-of-env/lib/python3.4/
To check the path you type:
import sys
sys.path

Try entering the following in your terminal:
conda install seaborn
It will install seaborn and make it available for you to import into your notebook

Open anaconda prompt and Type
pip install seaborn
