Mamba on LANTA HPC

Load

...

Mamba module

  1. Use the ml av MinicondaMamba command to see which version of Miniconda Mamba is available on the LANTA HPC system.

  2. Use the ml Miniconda3Mamba/xx.xx.x command to load the Miniconda Mamba version that you want to use. If you don't specify a version, the default version (D) is loaded, which is Miniconda3Mamba/2223.11.10-10.

username@lanta:~> ml av MinicondaMamba
---------------------- /lustrefs/disk/modules/easybuild/modules/all -----------------------
   Miniconda3Mamba/2223.11.1-10-0 (D)

Use "module spider" to find all possible modules and extensions.
Use "module keyword key1 key2 ..." to search for all possible modules matching any of the "keys".

Unload Mamba module

Use the

...

module unload Mamba command to unload the Mamba.

Code Block
username@lanta:~> condamodule env unload Mamba

Use the module purge command to unload all currently loaded modules.

Code Block
username@lanta:~> module purge
Note

Before you use the module unload Mamba or module purge command, you must deactivate your environment with the conda deactivate command.

Activate your environment

  1. Use the conda env list command to view a list of your environments.

  2. If you want to activate your environment such as TensorFlow-2.6.0, you can use the conda activate tensorflow-2.12.1 command.

Code Block
username@lanta:~> conda env list
