Conda (Anaconda)

We encourage users to install Conda in their HOME directories since it does not make sense to host a global Conda installation.

Please carefully follow the installation procedure as shown here.

If you have any remnants of conda mentions in your $HOME/.bashrc please delete all of these before proceeding.

Miniconda 24.5.0 (June 2024)

This procedure has been tested with the 24.5.0 release of Miniconda. It will likely work for later versions.

1. Download the executable, it should be named something like Miniconda3-latest-Linux-x86_64.sh.
2. Run the installer by issuing (this will install it in your HOME directory, with the folder name miniconda3):
   sh Miniconda3-latest-Linux-x86_64.sh -b -u -p ~/miniconda3
   This installation procedure uses appropriate defaults.
3. Generally, when you need to use conda, you should source it.
   Do this:
   source ~/miniconda3/bin/activate
   If you want to use Conda in your job-scripts, you also need to add the above in your submit scripts.
4. IMPORTANT:
   By default, Miniconda downloads files from the public Anaconda repository. However, the Terms of Service forbids DTU employees to use it in research.
   Please execute the following commands to remove the use of the public Anaconda repository. It will then only use the conda-forge repository:
   conda config --add channels conda-forge
conda config --remove channels defaults
   
   Please: do not install anything from the public Anaconda repositories.

The 4th step above is crucial in order to ensure that we, as a large organization, upholds the Terms of Service.

Automatically sourcing conda when you login

# Set up the bash environment if interactive login.
if tty -s ; then
   # lots of code
fi

Change it so that it looks like this:

# Set up the bash environment if interactive login.
if tty -s ; then
   # lots of code
   source $HOME/miniconda3/bin/activate
fi

Miniforge

Feel free to install Miniforge as your conda provider. It defaults to the conda-forge channel, which is fully open source.
