Installing Matplotlib in Visual Studio Code

In this video tutorial, we will learn to use "matplotlib" and "numpy" packages to create a graphical plot as is commonly done with data science.
Step 1: Create a file with the name: firstplot.py
******************************************
import matplotlib.pyplot as plt
import numpy as np
x = np.linspace(0, 20, 100)
plt.plot(x, np.sin(x))
plt.show()
*******************************************
Now run the file in the debugger using the "Python: Current file"
you would see a message, "ModuleNotFoundError: No module named 'matplotlib'". Such a message indicates that the required package isn't available in your system.
Step 2: 'matplotlib' package installation (which also installs numpy as a dependency):
open Command Palette to run Terminal: Create New Integrated Terminal (Ctrl+Shift+`).
Note: We will create a virtual environment and install the required packages, Such isolation reduces many complications that can arise from conflicting package versions.
**Enter the following command:
py -3 -m venv .venv
.venv\scripts\activate
Important:
***********
If the activate command generates the message "Activate.ps1 is not digitally signed. You cannot run this script on the current system.", then you need to temporarily change the PowerShell execution policy to allow scripts to run.
Set -ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope Process
Step 3: Select your new environment by using the Python: Select Interpreter command from the Command Palette.
Run the following command:
python -m pip install matplotlib
Step 4: Deactivate environment:
Once you are finished,
type "deactivate" in the terminal window to deactivate the virtual environment.

I'm a computer science student and I can say this is highly effective. It took me approx. 30 min for me to figure out how to solve "You cannot run this script on the current system" error though. Thanks a million.

[@Bagnesium]

why did you comment?

[@adamclarke403]

Have been pulling out my hair for the past 30 minutes trying to figure this out. Thank you so much, have a glorious day my friend!

[@CoolITHelp]

You are so welcome

[@efecantepe3990]

I am a computer science student and I decided to use matplotlib for my homework. first time in the history of my education. I made the configuration of my setup less than 10 minutes. thank you.

[@Aeorith]

Thank you so much for this tutorial! I postponed installing matplotlib for such a long time, cause I didn't find a proper tutorial, but with this it was really easy! :D

What if I don't create a virtual environment for this ?

[@lukassemrau1726]

I have an error: import matplotlib.pyplot as plt
IndentationError: unexpected indent
What should i do

[@prashilthul6579]

hey bro plz share your code with me i can try to resolve it but most probably its just a error of indentation (you might have not given proper spaces/tabs so plz do check it)

[@juansebastiancasalinsoreju8205]

Godlike

[@faiqhilman4300]

how do i change the powershell script policy???

[@rojadsorum9515]

venev is not activated in the system what to do

[@Supercool7042]

why the fuck it is still not installing in my computer
i did this 3-4 times but still not.
everything is working fine but when run this 'python -m pip install matplotlib ' it gives error😤😤😤😤😤😤

[@isabellanamuddu9639]

I cant find the virtual environment i just created

[@Aeorith]

I had the same issue, restarting VS Code helped. Once I open VS Code again, simply do the .venv\scripts\activate command again, and then you can choose the virtual environment as interpreter :)

[@rojadsorum9515]

pip is not module

[@candy7333]

sadly, error happends

[@BarakaGitari]

thank you!
