Enabling conda in Windows Powershell

First, in an administrator command prompt, enable unrestricted Powershell script execution (see About Execution Policies):

set-executionpolicy unrestricted

Then makes sure that the conda Script directory in is your Path. For instance, with miniconda: %USERPROFILE%\Miniconda3\Scripts.

In a regular Powershell prompt check if conda is working, and update to latest version:

conda update conda
conda --version
# should be conda 4.6.1 or newer

Setup conda for Powershell using the following command:

conda init powershell

Finally, restart powershell. An initialisation script is run every time Powershell starts. You should now be able to activate environment with:

conda activate <my-env>
