Installation#
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. The Conda package manager is the recommended installation method for most users.
Instructions for installing from source, PyPI, or a development version are also provided.
Python version support#
Officially Python 3.9, 3.10, 3.11 and 3.12.
Installing pandas#
Installing with Anaconda#
For users that are new to Python, the easiest way to install Python, pandas, and the packages that make up the PyData stack (SciPy, NumPy, Matplotlib, and more) is with Anaconda, a cross-platform (Linux, macOS, Windows) Python distribution for data analytics and scientific computing. Installation instructions for Anaconda can be found here.
Installing with Miniconda#
For users experienced with Python, the recommended way to install pandas with Miniconda. Miniconda allows you to create a minimal, self-contained Python installation compared to Anaconda and use the Conda package manager to install additional packages and create a virtual environment for your installation. Installation instructions for Miniconda can 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 -c conda-forge -n name_of_my_env python pandas
This will create a minimal environment with only Python and pandas installed. To put your self inside this environment run.
source activate name_of_my_env
# On Windows
activate name_of_my_env
Installing from PyPI#
pandas can be installed via pip from PyPI.
pip install pandas
Note
You must have pip>=19.3
to install from PyPI.
Note
It is recommended to install and run pandas from a virtual environment, for example, using the Python standard library’s venv
pandas can also be installed with sets of optional dependencies to enable certain functionality. For example, to install pandas with the optional dependencies to read Excel files.
pip install "pandas[excel]"
The full list of extras that can be installed can be found in the dependency section.
Handling ImportErrors#
If you encounter an ImportError
, it usually means that Python couldn’t find pandas in the list of available
libraries. Python internally has a list of directories it searches through, to find packages. You can
obtain these directories with.
import sys
sys.path
One way you could be encountering this error is if you have multiple Python installations on your system
and you don’t have pandas installed in the Python installation you’re currently using.
In Linux/Mac you can run which python
on your terminal and it will tell you which Python installation you’re
using. If it’s something like “/usr/bin/python”, you’re using the Python from the system, which is not recommended.
It is highly recommended to use conda
, for quick installation and for package and dependency updates.
You can find simple installation instructions for pandas in this document.
Installing from source#
See the contributing guide 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.
Installing the development version of pandas#
Installing the development version is the quickest way to:
Try a new feature that will be shipped in the next release (that is, a feature from a pull-request that was recently merged to the main branch).
Check whether a bug you encountered has been fixed since the last release.
The development version is usually uploaded daily to the scientific-python-nightly-wheels index from the PyPI registry of anaconda.org. You can install it by running.
pip install --pre --extra-index https://pypi.anaconda.org/scientific-python-nightly-wheels/simple pandas
Note that you might be required to uninstall an existing version of pandas to install the development version.
pip uninstall pandas -y
Running the test suite#
pandas is equipped with an exhaustive set of unit tests. The packages required to run the tests
can be installed with pip install "pandas[test]"
. To run the tests from a
Python terminal.
>>> import pandas as pd
>>> pd.test()

Dependencies#
Required dependencies#
pandas requires the following dependencies.
Package |
Minimum supported version |
---|---|
1.22.4 |
|
2.8.2 |
|
2020.1 |
|
2022.7 |
Optional dependencies#
pandas has many optional dependencies that are only used for specific methods.
For example, pandas.read_hdf()
requires the pytables
package, while
DataFrame.to_markdown()
requires the tabulate
package. If the
optional dependency is not installed, pandas will raise an ImportError
when
the method requiring that dependency is called.
If using pip, optional pandas dependencies can be installed or managed in a file (e.g. requirements.txt or pyproject.toml)
as optional extras (e.g. pandas[performance, aws]
). All optional dependencies can be installed with pandas[all]
,
and specific sets of dependencies are listed in the sections below.
