Installation — pandas 0.25.3 documentation (original) (raw)

The easiest way to install pandas is to install it as part of the Anaconda distribution, a cross platform distribution for data analysis and scientific computing. This is the recommended installation method for most users.

Instructions for installing from source,PyPI, ActivePython, various Linux distributions, or adevelopment version are also provided.

Python version support¶

Officially Python 3.5.3 and above, 3.6, 3.7, and 3.8.

Installing pandas¶

Installing with Anaconda¶

Installing pandas and the rest of the NumPy andSciPy stack can be a little difficult for inexperienced users.

The simplest way to install not only pandas, but Python and the most popular packages that make up the SciPy stack (IPython, NumPy,Matplotlib, …) is withAnaconda, a cross-platform (Linux, Mac OS X, Windows) Python distribution for data analytics and scientific computing.

After running the installer, the user will have access to pandas and the rest of the SciPy stack without needing to install anything else, and without needing to wait for any software to be compiled.

Installation instructions for Anaconda can be found here.

A full list of the packages available as part of theAnaconda distributioncan be found here.

Another advantage to installing Anaconda is that you don’t need admin rights to install it. Anaconda can install in the user’s home directory, which makes it trivial to delete Anaconda if you decide (just delete that folder).

Installing with Miniconda¶

The previous section outlined how to get pandas installed as part of theAnaconda distribution. However this approach means you will install well over one hundred packages and involves downloading the installer which is a few hundred megabytes in size.

If you want to have more control on which packages, or have a limited internet bandwidth, then installing pandas withMiniconda may be a better solution.

Conda is the package manager that theAnaconda distribution is built upon. It is a package manager that is both cross-platform and language agnostic (it can play a similar role to a pip and virtualenv combination).

Miniconda allows you to create a minimal self contained Python installation, and then use theConda command to install additional packages.

First you will need Conda to be installed and downloading and running the Minicondawill do this for you. The installercan be found here

The next step is to create a new conda environment. A conda environment is like a virtualenv that allows you to specify a specific version of Python and set of libraries. Run the following commands from a terminal window:

conda create -n name_of_my_env python

This will create a minimal environment with only Python installed in it. To put your self inside this environment run:

source activate name_of_my_env

On Windows the command is:

The final step required is to install pandas. This can be done with the following command:

To install a specific pandas version:

conda install pandas=0.20.3

To install other packages, IPython for example:

To install the full Anacondadistribution:

If you need packages that are available to pip but not conda, then install pip, and then use pip to install those packages:

conda install pip pip install django

Installing from PyPI¶

pandas can be installed via pip fromPyPI.

Installing with ActivePython¶

Installation instructions forActivePython can be foundhere. Versions 2.7 and 3.5 include pandas.

Installing using your Linux distribution’s package manager.¶

The commands in this table will install pandas for Python 3 from your distribution. To install pandas for Python 2, you may need to use the python-pandas package.

However, the packages in the linux package managers are often a few versions behind, so to get the newest version of pandas, it’s recommended to install using the pip or condamethods described above.

Running the test suite¶

pandas is equipped with an exhaustive set of unit tests, covering about 97% of the code base as of this writing. To run it on your machine to verify that everything is working (and that you have all of the dependencies, soft and hard, installed), make sure you have pytest >= 4.0.2 and Hypothesis >= 3.58, then run:

pd.test() running: pytest --skip-slow --skip-network C:\Users\TP\Anaconda3\envs\py36\lib\site-packages\pandas ============================= test session starts ============================= platform win32 -- Python 3.6.2, pytest-3.6.0, py-1.4.34, pluggy-0.4.0 rootdir: C:\Users\TP\Documents\Python\pandasdev\pandas, inifile: setup.cfg collected 12145 items / 3 skipped

Dependencies¶

Recommended dependencies¶

• numexpr: for accelerating certain numerical operations.numexpr uses multiple cores as well as smart chunking and caching to achieve large speedups. If installed, must be Version 2.6.2 or higher.
• bottleneck: for accelerating certain types of nanevaluations. bottleneck uses specialized cython routines to achieve large speedups. If installed, must be Version 1.2.1 or higher.

Note

You are highly encouraged to install these libraries, as they provide speed improvements, especially when working with large data sets.

Optional dependencies¶

Pandas has many optional dependencies that are only used for specific methods. For example, pandas.read_hdf() requires the pytables package. If the optional dependency is not installed, pandas will raise an ImportError when the method requiring that dependency is called.
