Question

I have tried installing numpy from my terminal and it is giving me complicated error message. PLease somebody help me, am very new to pythoin and pycharm

Executing pip3 install numpy command:

Answer 1

You seem to be using python 3.9. numpy is not available for it yet.

Question seems to be a duplicate of:

trying to install numpy in python3.9 and getting error in preparing wheel metadata in windows 10. I did not checked using virtual environment

Answer 2

Step 1: Check Python Version Before you can install NumPy, you need to know which Python version you have. This programming language comes preinstalled on most operating systems (except Windows; you will need to install Python on Windows manually).

Most likely, you have Python 2 or Python 3 installed, or even both versions.

To check whether you have Python 2, run the command:

python -V

The output should give you a version number.

To see if you have Python 3 on your system, enter the following in the terminal window:

python3 -V

In the example below, you can see both versions of Python are present.

Step 3: Download PIP get-pip.py

Before installing PIP, download the get-pip.py file: get-pip.py on pypa.io.

Download the file to the desired folder in Windows. You can save the file to any location, but remember the path so you can use it later.

Step 4: Installing PIP on Windows Open the Command Prompt if it isn’t already open. Use the cd command followed by a folder name to navigate to the location of the get-pip.py file. This is the folder you previously used as the download location.

To install PIP type in the following:

python get-pip.py PIP installation should start. If the file isn’t found, double-check the path to the folder where you saved the file.

You can view the contents of your current directory using the following command:

dir

The dir command returns a full listing of the contents of a directory.

Step 4: How to Check PIP Version To check the current version of PIP, type the following command:

pip --version

This command returns the current version of the platform.

Step 5: Install NumPy With Pip set up, you can use its command line for installing NumPy.

Install NumPy with Python 2 by typing:

pip install numpy

Pip downloads the NumPy package and notifies you it has been successfully installed.
