NumPy - Installing NumPy
The recommended method of installing NumPy depends on your preferred workflow. Below, we break down the installation methods into the following categories: Project-based (e.g., uv, pixi) (recommended for new users) Environment-based (e.g., pip, conda) (the traditional workflow)

r/learnpython on Reddit: How to Install Numpy
June 10, 2025 -
A coworker sent me a Python file that uses numpy, so when I tried to run it, I got the error "No module named 'numpy'". So I looked up numpy, and it said in order to get that, I needed either conda or pip. so I looked up how to get conda, and it said I had to first download Anaconda. So I download Anaconda. I look in there and it would seem to me that both conda and numpy are already in there: Under Environments, both conda and numpy are listed as installed. But then I went back and tried to run the program again, and I got the same error. What else do I need to do to access numpy?
Also, idk if this matters, but I'm running Python on IDLE. Do I need to use a different IDE?

Couple of options. Are you on windows? I'll just assume windows for now. You can run the script in the conda environment, base, created when you installed anaconda. Typically this is like, open the anaconda navigator. Select command prompt or powershell. Or, skip the navigator and just search your computer for "Anaconda prompt", which should open a terminal with base activated already. Then, you should see the (base) prefix left of the terminal interface. You can start from any sort of terminal, and activate the (base) environment activation script as well. What the activation script essentially does is it sets some temporary variables in your terminal to tell your computer which special folders to search for certain binaries (like python) / packages / libraries. The other method is if you have a global python install, you already have a global pip. This would've worked without anaconda. open cmd and run pip install numpy If you're in a locked-down coorporate environment, you may have some issues, but otherwise this is what you needed. You can also use the venv module to create virtual environments (similar to conda environments, but not 100% the same). They just let you keep different projects with different requirements, or different version requirements, isolated in their own 'virtual' environment. These typically install the dependencies in the same project folder, next to your code. whereas conda has a hidden folder somewhere with all your environments. I've been enjoying uv for managing different python virtual environments. It's another binary you install, but it lets you quickly create virtual environments, specify the python version, pin dependencies (like numpy in your case) and install them into your virtual environments. uv sort of keeps track of everything you use it, not quite like conda. If this is the only use of python you have, is running this one script, then you really can just run it all in a global python install and not worry about virtual environments. But it's good to know the what and why.

Check the installation of Python 2.7, and then install/reinstall pip which is described here. Then a open command line windows and write:
pip install numpy
Or
pip install scipy
If already installed, try this:
pip install -U numpy

Installing extension modules can be an issue with pip. This is why Conda exists. Conda is an open-source BSD-licensed cross-platform package manager. It can easily install NumPy.
Two options:
- Install Anaconda here
- Install Miniconda here and then go to a command line and type
conda install numpy(make sure your PATH includes the location Conda was installed to).

You have to install numpy from Command Prompt, not IDLE.
Follow these steps on Windows:
- Press the Windows key on your keyboard.
- Type CMD and open Command Prompt. A black terminal should open up.
- Type 'pip install numpy' and hit enter.
- It should start the installation. After you see the "Successfully Installed" message, go back to your IDLE and try importing numpy, it should work.
NOTE: In case you get a message saying "pip" is not recognized, refer to: https://stackoverflow.com/a/56678271/13699502

You write pip install numpy in the command prompt (CMD) if you are on Windows.
And, most of the times py -m pip install numpy helps more on Windows.
On macOS/Unix, you can use python -m pip install numpy in terminal/console.
