If you want to do data analysis in python, you always need to use python packages like Numpy, Pandas, Scipy and Matplotlib etc. All those python packages are so powerful and useful to do Base N-dimensional array computing( Numpy ), Data structures & analysis ( Pandas ), scientific computing ( Scipy) and Comprehensive 2D Plotting ( Matplotlib ). But the first step is to install the related packages on your OS, this article will tell you how to install it on Windows, Mac and Linux.
1. Install Numpy, Pandas, Scipy, Matplotlib With Anacond.
Anaconda is a python edition which is used in scientific area, so if you install anaconda, all above packages will be installed automatically. So please read article How To Install Anaconda On Linux, Windows, MacOS Correctly to install anaconda first.
After installation, you can run command conda in a terminal to list above packages to make sure it has been installed correctly.
~$ conda list pandas # packages in environment at /home/zhaosong/anaconda3: # # Name Version Build Channel pandas 0.23.4 py37h04863e7_0
To list all installed anconda packages, just run
$ conda list.
$ conda -h to list conda command help information.
If you want to remove / uninstall a package, run
$ conda remove <package name>
2. Install Numpy, Pandas, Scipy, Matplotlib By PIP Command.
- First make sure pip has been installed on your OS. If not installed please refer article How To Install Python/Pip On Windows.
~$ pip --version pip 18.1 from /home/zhaosong/anaconda3/lib/python3.7/site-packages/pip (python 3.7)
- Run pip install command to install related packages.
pip install numpy pip install pandas pip install scipy pip install matplotlib
- Run pip uninstall command to uninstall related packages.
pip uninstall numpy pip uninstall pandas pip uninstall scipy pip uninstall matplotlib
- Run pip show command to display package install information.
