Mac Install Python3 Pip

There are different ways to install scikit-learn:

Simply run following on terminal if you don't have pip installed on your mac. Sudo easyinstall pip. Download python 3 here: python3. Once you're done with these 2 steps, make sure to run the following to verify whether you've installed them successfully. Python3 -version pip3 -version. Improve this answer. Step 1: Update teh packege list. Sudo apt update. Step 2: Install the pip for Python 3 using the apt install command. Sudo apt install python3-pip. The above command will install all the dependencies and install pip on the ubuntu for Python 3. Step3: Verify the installation by checking the pip version.

  • 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.

Python3 -m pip show scikit-learn # to see which version and where scikit-learn is installed python3 -m pip freeze # to see all packages installed in the active virtualenv python3 -c 'import sklearn; sklearn.showversions' python -m pip show scikit-learn # to see which version and where scikit-learn is installed python -m pip freeze # to see all packages installed in the active virtualenv.

Installing the latest release¶

Operating System
Install the 64bit version of Python 3, for instance from Python 3 using homebrew (brew install python) or by manually installing the package from 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).

Then run:

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 now requires Python 3.6 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 asmacos/aarch64) requires the open source community to upgrade the buildconfiguation 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¶

Mac Install Python3 Pip

Pip Install Virtualenv Python3 Mac

Arch Linux’s package is provided through the official repositories aspython-scikit-learn for Python.It can be installed by typing the following command:


The Debian/Ubuntu package is splitted in three different packages calledpython3-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 apt-get:


The Fedora package is called python3-scikit-learn for the python 3 version,the only one available in Fedora30.It can be installed using dnf:


scikit-learn is available via pkgsrc-wip:

MacPorts for Mac OSX¶

The MacPorts package is named py<XY>-scikits-learn,where XY denotes the Python version.It can be installed by typing the followingcommand:

Mac Install Python3 Pip

Anaconda and Enthought Deployment Manager for all supported platforms¶

Anaconda andEnthought Deployment Managerboth ship with scikit-learn in addition to a large set of scientificpython library for Windows, Mac OSX and Linux.

Python 3 Pip Install Mac Software

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

WinPython for Windows¶

The WinPython project distributesscikit-learn as an additional plugin.


Error caused by file path length limit on Windows¶

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 theAppData 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 regedit tool:

  1. Type “regedit” in the Windows start menu to launch regedit.

  2. Go to theComputerHKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlFileSystemkey.

  3. Edit the value of the LongPathsEnabled property of that key and setit to 1.

  4. Reinstall scikit-learn (ignoring the previous broken installation):

Apple’s Mac OS comes with python 2.7 installed by default. Perhaps you may want to use python 3.x.x on your machine and also use pip for package management with python 3.x.x. The easiest way to achieve this is by:

NOTE: This tutorial does not useVirtual Environments like virtualenv or pyenv to manage various python versions

1. Installing python3

  • Follow this link and download the latest python3OS X package
  • Run the package and follow the steps to install python3 on your computer.
  • Once the installation is done, on your Terminal, run

This will print out the version of python installed on your system. The output should be similar to:

Mac Install Python 3 Pip Windows 10

You may verify the installation directory of python by runningthe following line on the Terminal.


The prompt should print the install path for python3. An example output is:

2. Install pip3:

  • Securely download the file from this link
  • From the directory where the file was downloaded to, run the following command in the Terminal
  • Once the installation completes you should see the prompt print message similar to this
  • Verify the installation of pip3 by running the following on the Terminal

This should return the install location of pip3.

  • To install python3 packages using pip3, run

Remember to replace packageName with the appropriate package name for your case.
