Installation¶
The easiest way for the majority of users 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, various Linux distributions, or a development version are also provided.
Python version support¶
Officially Python 2.7, 3.5, and 3.6.
Installing pandas¶
Installing pandas with Anaconda¶
Installing pandas and the rest of the NumPy and SciPy 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 with Anaconda, a cross-platform (Linux, Mac OS X, Windows) Python distribution for data analytics and scientific computing.
After running a simple 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 the Anaconda distribution can be found here.
An additional advantage of installing with Anaconda is that you don’t require admin rights to install it, it will install in the user’s home directory, and this also makes it trivial to delete Anaconda at a later date (just delete that folder).
Installing pandas with Miniconda¶
The previous section outlined how to get pandas installed as part of the Anaconda 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 with Miniconda may be a better solution.
Conda is the package manager that the Anaconda 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 the Conda command to install additional packages.
First you will need Conda to be installed and downloading and running the Miniconda will do this for you. The installer can be found here
The next step is to create a new conda environment (these are analogous to a virtualenv but they also allow you to specify precisely which Python version to install also). 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:
activate name_of_my_env
The final step required is to install pandas. This can be done with the following command:
conda install pandas
To install a specific pandas version:
conda install pandas=0.20.3
To install other packages, IPython for example:
conda install ipython
To install the full Anaconda distribution:
conda install anaconda
If you require any packages that are available to pip but not conda, simply install pip, and use pip to install these packages:
conda install pip
pip install django
Installing from PyPI¶
pandas can be installed via pip from PyPI.
pip install pandas
This will likely require the installation of a number of dependencies, including NumPy, will require a compiler to compile required bits of code, and can take a few minutes to complete.
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 package python-pandas
.
Distribution | Status | Download / Repository Link | Install method |
---|---|---|---|
Debian | stable | official Debian repository | sudo apt-get install python3-pandas |
Debian & Ubuntu | unstable (latest packages) | NeuroDebian | sudo apt-get install python3-pandas |
Ubuntu | stable | official Ubuntu repository | sudo apt-get install python3-pandas |
OpenSuse | stable | OpenSuse Repository | zypper in python3-pandas |
Fedora | stable | official Fedora repository | dnf install python3-pandas |
Centos/RHEL | stable | EPEL repository | yum install python3-pandas |
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 conda
methods described above.
Installing from source¶
See the contributing documentation for complete instructions on building from the git source tree. Further, see creating a development environment if you wish to create a pandas development environment.
Running the test suite¶
pandas is equipped with an exhaustive set of unit tests covering about 97% of the codebase as of this writing. To run it on your machine to verify that everything is working (and you have all of the dependencies, soft and hard, installed), make sure you have pytest and run:
>>> import pandas as pd
>>> pd.test()
running: pytest --skip-slow --skip-network C:\Users\TP\Anaconda3\envs\py36\lib\site-packages\pandas
============================= test session starts =============================

Dependencies¶
- setuptools
- NumPy: 1.9.0 or higher
- python-dateutil: 1.5 or higher
- pytz: Needed for time zone support
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 2.4.6 or higher. - bottleneck: for accelerating certain types of
nan
evaluations.bottleneck
uses specialized cython routines to achieve large speedups. If installed, must be Version 1.0.0 or higher.
Note
You are highly encouraged to install these libraries, as they provide large speedups, especially if working with large data sets.
Optional Dependencies¶
Cython: Only necessary to build development version. Version 0.23 or higher.
SciPy: miscellaneous statistical functions, Version 0.14.0 or higher
xarray: pandas like handling for > 2 dims, needed for converting Panels to xarray objects. Version 0.7.0 or higher is recommended.
PyTables: necessary for HDF5-based storage. Version 3.0.0 or higher required, Version 3.2.1 or higher highly recommended.
Feather Format: necessary for feather-based storage, version 0.3.1 or higher.
Apache Parquet, either pyarrow (>= 0.4.1) or fastparquet (>= 0.0.6) for parquet-based storage. The snappy and brotli are available for compression support.
SQLAlchemy: for SQL database support. Version 0.8.1 or higher recommended. Besides SQLAlchemy, you also need a database specific driver. You can find an overview of supported drivers for each SQL dialect in the SQLAlchemy docs. Some common drivers are:
matplotlib: for plotting, Version 1.4.3 or higher.
For Excel I/O:
- xlrd/xlwt: Excel reading (xlrd) and writing (xlwt)
- openpyxl: openpyxl version 1.6.1 or higher (but lower than 2.0.0), or version 2.2 or higher, for writing .xlsx files (xlrd >= 0.9.0)
- XlsxWriter: Alternative Excel writer
Jinja2: Template engine for conditional HTML formatting.
s3fs: necessary for Amazon S3 access (s3fs >= 0.0.7).
blosc: for msgpack compression using
blosc
One of PyQt4, PySide, pygtk, xsel, or xclip: necessary to use
read_clipboard()
. Most package managers on Linux distributions will havexclip
and/orxsel
immediately available for installation.pandas-gbq: for Google BigQuery I/O.
Backports.lzma: Only for Python 2, for writing to and/or reading from an xz compressed DataFrame in CSV; Python 3 support is built into the standard library.
One of the following combinations of libraries is needed to use the top-level
read_html()
function:- BeautifulSoup4 and html5lib (Any recent version of html5lib is okay.)
- BeautifulSoup4 and lxml
- BeautifulSoup4 and html5lib and lxml
- Only lxml, although see HTML Table Parsing for reasons as to why you should probably not take this approach.
Warning
- if you install BeautifulSoup4 you must install either
lxml or html5lib or both.
read_html()
will not work with only BeautifulSoup4 installed. - You are highly encouraged to read HTML Table Parsing gotchas. It explains issues surrounding the installation and usage of the above three libraries.
- You may need to install an older version of BeautifulSoup4: Versions 4.2.1, 4.1.3 and 4.0.2 have been confirmed for 64 and 32-bit Ubuntu/Debian
Note
if you’re on a system with
apt-get
you can dosudo apt-get build-dep python-lxml
to get the necessary dependencies for installation of lxml. This will prevent further headaches down the line.
Note
Without the optional dependencies, many useful features will not work. Hence, it is highly recommended that you install these. A packaged distribution like Anaconda, or Enthought Canopy may be worth considering.
