Note that you should always remember to activate the environment of your choice Package manager of the distribution (apt, dnf, pacman…). In particular under Linux is itĭiscouraged to install pip packages alongside the packages managed by the Version of scikit-learn with pip or conda and its dependencies independently ofĪny previously installed Python packages. Using such an isolated environment makes it possible to install a specific

Strongly recommended to use a virtual environment (venv) or a conda environment.

Note that in order to avoid potential conflicts with other packages it is 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.show_versions()' 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 python -c 'import sklearn sklearn.show_versions()' 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 python -c 'import sklearn sklearn.show_versions()' 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 python -c 'import sklearn sklearn.show_versions()' conda list scikit-learn # to see which scikit-learn version is installed conda list # to see all packages installed in the active conda environment python -c 'import sklearn sklearn.show_versions()'
