Installing NumPy
NumPy is the fundamental package for scientific computing in Python. NumPy is used for working with arrays.
The only prerequisite for installing NumPy is Python itself.
Step 1: Check if PIP is Installed
Before installing NumPy, it's essential to ensure that PIP (Python Package Installer) is installed on your system. PIP is a package management system used to install and manage Python packages. You can verify if PIP is installed by running a simple command in your terminal or command prompt.
pip --version
If PIP is not currently installed on your system, you can install it by visiting the pypi.org webpage.
Step 2: Installing PIP
get-pip.py
This is a Python script that uses some bootstrapping logic to install pip.
Open a terminal / command prompt and run:
Linux
python get-pip.py
Windows
py get-pip.py
MacOS
python get-pip.py
Step 3: Installing NumPy
NumPy can be installed either through conda or pip.
If you use pip, you can install NumPy with:
pip install numpy
If you use conda, you can install NumPy from the defaults or conda-forge channels:
# Best practice, use an environment rather than install in the base env
conda create -n my-env
conda activate my-env
# If you want to install from conda-forge
conda config --env --add channels conda-forge
# The actual install command
conda install numpy
You can find more information about how to install NumPy on numpy.org.
Step 4: Check if NumPy is Installed
We can utilize the "pip show" command not only to display the version but also to determine whether NumPy is installed on the system.
pip show numpy
