Customizing Jupyterlab with Anaconda environments
Step one is to load an anaconda_<cpu, gpu, mi100> that you want to use as your base installation and initialize your default login shell to use conda environments.
Select an anaconda3:
[arnoldg@dt-login03 scripts]$ module load anaconda3_cpu [arnoldg@dt-login03 scripts]$ conda init bash ... [arnoldg@dt-login03 scripts]$ bash (base)
After you have run "conda init bash" you will not need to load anaconda3_cpu (or gpu ) modules again. Just use your new custom environment.
conda init bash error messages
You may see error messages from conda init bash above. Just control-c through them and continue. As long as conda added code to the end of your .bashrc (or similar for other shells), things will work properly.
Start a new shell with bash or a new terminal or login session with Delta. You'll now see this prompt showing that you are within the conda environment you initially chose. If you want to change environments later (say to anaconda3_mi100) you can edit your .bashrc and do another "conda init bash" with that new module loaded.
To create a new custom environment, you have 2 options.
Create a new empty environment:
cpu, gpu, or mi100
If you will be making custom environments for more than one partition type (cpu, gpu, mi100), it may be helpful to include that metadata in the name of your environment.
Install jupyter into the environment in order to use it with OpenOnDemand. This option adds about 150 python modules to your environment and requires about 1.3 GB in your $HOME. Setup time: about 10 minutes.

...or create a new clone of your chosen anaconda3_<cpu, gpu, mi100> module:
Jupyter (and everything else from your loaded anaconda3_ module will be copied into this environment). This option adds about 500 python modules to your environment and requires about 6.3 GB in your $HOME. Install time can be up to 1/2 hr.

Start an OpenOnDemand Jupyterlab session and access one of your environments (remember to match your partition and account types for gpu, cpu), then select the matching kernel for your Jupyter work:
After filling in the OpenOnDemand form and submitting your job, it will start in a few minutes showing the "Connect to Jupyter" button when ready.
Hover over items in the Launcher view to see which environment will be used, selecting the one you want for this session.
Change your kernel to match if you are opening a notebook from a different environment.
R is available in Jupyterlab by activating the environment via the module anaconda_Rcpu. Append the module load line to your .bashrc. R will run on the cpu cores (not gpu enabled).
$ tail .bashrc module load anaconda3_Rcpu $
After modifying your .bashrc and getting a new shell, your login prompt should reflect that you are within the anaconda3_Rcpu environment, R will be in your $PATH, and starting Jupyterlab from the OpenOnDemand interface will automatically offer you the R options with the Launcher.
Proceed to use R:
