I am trying to use matplotlib and pandas in one of my projects, and the error message I get is confusing me. I have done anything I can to resolve it, but it still doesn't work. There might be a problem with my Anaconda (i am using anaconda python) distribution or a problem with the path, but I checked and the path seemed to point to Anaconda

Every time I write this code:

import matplotlib as plt
import pandas as pd

it says there is an error. The error is:

PS C:\Users\mghaf\Documents\GitHub\Modelling-Cell-Growth-in-CFU> & C:/Users/mghaf/Anaconda3/envs/rstudio/python.exe c:/Users/mghaf/Documents/GitHub/Modelling-Cell-Growth-in-CFU/test.py      
Traceback (most recent call last):
  File "c:/Users/mghaf/Documents/GitHub/Modelling-Cell-Growth-in-CFU/test.py", line 1, in <module>
    import matplotlib as plt
ModuleNotFoundError: No module named 'matplotlib'

And for Pandas:

PS C:\Users\mghaf\Documents\GitHub\Modelling-Cell-Growth-in-CFU> & C:/Users/mghaf/Anaconda3/envs/rstudio/python.exe c:/Users/mghaf/Documents/GitHub/Modelling-Cell-Growth-in-CFU/test.py      
Traceback (most recent call last):
  File "c:/Users/mghaf/Documents/GitHub/Modelling-Cell-Growth-in-CFU/test.py", line 2, in <module>
    import pandas as pd
ModuleNotFoundError: No module named 'pandas'

In vscode, I have checked all the libraries that I have, and it seems that I have everything, yet it still says module not found.

As you can see, matplotlib and pandas are there.

I a using anaconda to get my libraries. I am using Vscode for writing the program.

Maybe I need to do a complete uninstall of python and any attributes to it, and then install anything I need back to get a fresh system?

  • Could you please provide the output for `import sys; print(sys.executable)` – S P Sharan Aug 17 '21 at 02:59

I can see that the packages already exist in your base environment so there is no need to install any additional packages for now.

First you need to add anaconda to your path.

Please head here and scroll down to add anaconda to path (optional) https://www.datacamp.com/community/tutorials/installing-anaconda-windows and follow the instructions.

Once that it done, You need to type conda activate base in your command prompt and hit enter, then you can type code and you can launch your development environment.

Alternatively, you can look for anaconda prompt within the start button and launch it, it will automatically go into the anaconda base environment, then you can try to launch code by typing code.

If you can’t launch code, you can head here and follow the instructions to add vs code to your path, How to start Visual Studio Code within Anaconda Env just follow the steps in the first answer.

Then open a new CMD prompt and try typing the activate and code commands from above again or launching the anaconda prompt from within the start button again.

Alternatively, you can also add the anaconda environment directly into vs code using the following steps.

1   Ctrl + shift + P
2   Search Select Interpreter
3   Select it and it will show you the list of your virtual environment created via conda and other python versions
4   select the environment and you are ready to go.

Then you will be able to launch into your anaconda environment either by using the command prompt, activating the environment and launching code. Or you can launch code directly and select the anaconda environment from within.

You need to understand what anaconda is, it is just an environment creator and package manager. Each environment has its own packages you can control and destroy when you are done, it ensures that your environments are sandboxed so that they don’t affect one another or your system.

I recommend that you create a new environment, not use the base environment to do your work, to do this you can type conda create -n name where name is the name of the environment you can put whatever you want. After that you can do conda install pandas matplotlib etc and instead of launching into base you can now conda activate name and launch into this environment instead.

From your comment, the environment where the packages are installed in, and the interpreter you want to use are different.

Please do the following from an Anaconda command prompt.

conda activate rstudio
pip install matplotlib
pip install pandas

    @AlirezaGhaffarian A good and fast way to mess up a conda distribution / env is to pip install packages that existing as part of conda. It should be `conda install pandas` and `conda install matplotlib` – Trenton McKinney Aug 17 '21 at 03:35
