Small tutorial with starting steps and templates for using conda/mamba on the servers of Fachbereich 8.4

If you are using Windows, you can find the "official" PTB miniforge installation in the Softwarecenter

On the compute servers, a central installation of both conda and mamba is provided. mamba is functionally identical to conda, it is just a faster reimplementation in C++, use whichever you prefer, the commands are identical.

The executables of both programs are located in the /home/admin84/shared_public, which should be configured on all servers the be included in $PATH. You can verify you are using the correct executable by running conda info. If this returns a different location than above, please remove your personal previous installation of (ana)conda first.

If you have used conda before, you have update you bash initialisation first by running

conda init --reverse
conda init

You can use the .condarc template provided here to customise the locations where your environments and package caches are located when using conda. Please consider using the san for you paths to avoid cluttering the local drives.

Conda will be default use the python version which is installed on the host machine, but you can use any supported version when creating new environments, e.g.

mamba create python=3.12 numpy ipython --name mamba-test

. The default channel configured is conda-forge, which is still permitted by PTB. Please do not override this when creating new environments unless you are 100% certain that the licence of the channel in question permits use by PTB. When in doubt, please ask.

If any problems arise or you have further questions, please contact me and I will amend this document with clarifications and answer questions.
