Verify your installer hashes.
Miniconda---In your terminal window, run:
Follow the prompts on the installer screens.
If you are unsure about any setting, accept the defaults. Youcan change them later.
To make the changes take effect, close and then re-open yourterminal window.
Test your installation. In your terminal window orAnaconda Prompt, run the command

Installing in silent mode¶
The following instructions are for Miniconda. For Anaconda,substitute
Miniconda in all of the commands.
To run the silent installation ofMiniconda for macOS or Linux, specify the -b and -p arguments ofthe bash installer. The following arguments are supported:
Anaconda Python Install Mac High Sierra Optional: Launch Spyder or Jupyter Notebook from the command line¶ At the Anaconda Prompt (terminal on Linux or macOS), type spyder and press Enter.Spyder should start up just like it did when you launched itfrom Anaconda Navigator. See full list on datacamp.com. Anaconda works on Windows, Mac, and Linux, provides over 1,500 Python/R packages, and is used by over 15 million people. Anaconda is best suited to beginning users; it provides a large collection of libraries all in one.
-b: Batch mode with no PATH modifications to shell scripts.Assumes that you agree to the license agreement. Does not editshell scripts such as
-p: Installation prefix/path.
-f: Force installation even if prefix
The installer prompts “Do you wish the installer to initialize Miniconda3 by running
condainit?” We recommend “yes”.
If you enter “no”, then conda will not modify your shell scripts at all. In order to initialize after the installation process is done, first run
source<pathtoconda>/bin/activate and then run
macOS Catalina (and later)
If you are on macOS Catalina (or later versions), the default shell is zsh. You will instead need to run
source<pathtoconda>/bin/activate followed by
condainitzsh (to explicitly select the type of shell to initialize).
Updating Anaconda or Miniconda¶

Uninstalling Anaconda or Miniconda¶
Open a terminal window.
Remove the entire Miniconda install directory with:

Remove the following hidden file and folders that may havebeen created in the home directory:
There are different ways to install scikit-learn:
Install the latest official release. Thisis the best approach for most users. It will provide a stable versionand pre-built packages are available for most platforms.
Install the version of scikit-learn provided by youroperating system or Python distribution.This is a quick option for those who have operating systems or Pythondistributions that distribute scikit-learn.It might not provide the latest release version.
Building the package from source. This is best for users who want thelatest-and-greatest features and aren’t afraid of runningbrand-new code. This is also needed for users who wish to contribute to theproject.
Installing the latest release¶Operating System
brew install python) or by manually installing the package from https://www.python.org.Install python3 and python3-pip using the package manager of the Linux Distribution.Install conda using the Anaconda or miniconda installers or the miniforge installers (no administrator permission required for any of those).
In order to check your installation you can use
Note that in order to avoid potential conflicts with other packages it isstrongly recommended to use a virtual environment (venv) or a conda environment.
Using such an isolated environment makes it possible to install a specificversion of scikit-learn with pip or conda and its dependencies independently ofany previously installed Python packages. In particular under Linux is itdiscouraged to install pip packages alongside the packages managed by thepackage manager of the distribution (apt, dnf, pacman…).
Note that you should always remember to activate the environment of your choiceprior to running any Python command whenever you start a new terminal session.
If you have not installed NumPy or SciPy yet, you can also install these usingconda or pip. When using pip, please ensure that binary wheels are used,and NumPy and SciPy are not recompiled from source, which can happen when usingparticular configurations of operating system and hardware (such as Linux ona Raspberry Pi).
Scikit-learn plotting capabilities (i.e., functions start with “plot_”and classes end with “Display”) require Matplotlib. The examples requireMatplotlib and some examples require scikit-image, pandas, or seaborn. Theminimum version of Scikit-learn dependencies are listed below along with itspurpose.

Scikit-learn 0.20 was the last version to support Python 2.7 and Python 3.4.Scikit-learn 0.21 supported Python 3.5-3.7.Scikit-learn 0.22 supported Python 3.5-3.8.Scikit-learn 0.23 - 0.24 require Python 3.6 or newer.Scikit-learn 1.0 and later requires Python 3.7 or newer.
For installing on PyPy, PyPy3-v5.10+, Numpy 1.14.0+, and scipy 1.1.0+are required.
Installing on Apple Silicon M1 hardware¶
The recently introduced
macos/arm64 platform (sometimes also known as
macos/aarch64) requires the open source community to upgrade the buildconfiguration and automation to properly support it.
At the time of writing (January 2021), the only way to get a workinginstallation of scikit-learn on this hardware is to install scikit-learn and itsdependencies from the conda-forge distribution, for instance using the miniforgeinstallers:
The following issue tracks progress on making it possible to installscikit-learn from PyPI with pip:
Third party distributions of scikit-learn¶
Some third-party distributions provide versions ofscikit-learn integrated with their package-management systems.
These can make installation and upgrading much easier for users sincethe integration includes the ability to automatically installdependencies (numpy, scipy) that scikit-learn requires.
The following is an incomplete list of OS and python distributionsthat provide their own version of scikit-learn.
Arch Linux’s package is provided through the official repositories as
python-scikit-learn for Python.It can be installed by typing the following command:
The Debian/Ubuntu package is split in three different packages called
python3-sklearn (python modules),
python3-sklearn-lib (low-levelimplementations and bindings),
python3-sklearn-doc (documentation).Only the Python 3 version is available in the Debian Buster (the more recentDebian distribution).Packages can be installed using
The Fedora package is called
python3-scikit-learn for the python 3 version,the only one available in Fedora30.It can be installed using
scikit-learn is available via pkgsrc-wip:
MacPorts for Mac OSX¶
The MacPorts package is named
XY denotes the Python version.It can be installed by typing the followingcommand:
Anaconda and Enthought Deployment Manager for all supported platforms¶
Install Anaconda Python Macbook Pro
Anaconda andEnthought Deployment Managerboth ship with scikit-learn in addition to a large set of scientificpython library for Windows, Mac OSX and Linux.
Anaconda offers scikit-learn as part of its free distribution.
Intel conda channel¶
Intel maintains a dedicated conda channel that ships scikit-learn:
This version of scikit-learn comes with alternative solvers for some commonestimators. Those solvers come from the DAAL C++ library and are optimized formulti-core Intel CPUs.
Note that those solvers are not enabled by default, please refer to thedaal4py documentationfor more details.
Compatibility with the standard scikit-learn solvers is checked by running thefull scikit-learn test suite via automated continuous integration as reportedon https://github.com/IntelPython/daal4py.
WinPython for Windows¶
The WinPython project distributesscikit-learn as an additional plugin.
Install Python Anaconda Mac
Error caused by file path length limit on Windows¶
Install Anaconda Mac Python 3.6
It can happen that pip fails to install packages when reaching the default pathsize limit of Windows if Python is installed in a nested location such as the
AppData folder structure under the user home directory, for instance:
In this case it is possible to lift that limit in the Windows registry byusing the
Type “regedit” in the Windows start menu to launch
Go to the
Edit the value of the
LongPathsEnabledproperty of that key and setit to 1.
Reinstall scikit-learn (ignoring the previous broken installation):
