Updating a Specific Library - scikit-learn   Anaconda  conda    conda install scikit-learn   Pip Installs Packages  pip    pip install --upgrade scikit-learn   Verify Update   conda list scikit-learn   It should now display the current  and desired  version of the scikit-learn library   For me personally  I tried using the conda command to update the scikit-learn library and it acted as if it were installing the latest version to then later discover  with an execution of the conda list scikit-learn command  that it was the same version as previously and never updated  or recognized the update    When I used the pip command  it worked like a charm and correctly updated the scikit-learn library to the latest version    Hope this helps   More in-depth details of latest version can be found here  be mindful this applies to the scikit-learn library version of 0 22     Release Highlights for scikit-learn 0 22

I would suggest using conda  Conda is an anconda specific package manager  If you want to know more about conda  read the conda docs   Using conda in the command line  the command below would install scipy 0 17   conda install scipy 0 17 0

Anaconda comes with the conda package manager which is designed to handle these kinds of upgrades  Start by updating conda itself to get the most recent package lists   conda update conda   And then install the version of scikit-learn you want  conda install scikit-learn 0 17   All necessary dependencies will be upgraded as well  If you have trouble with conda on Windows  there are some relevant FAQ here  http   docs continuum io anaconda faq
