Switching to Anaconda2024

---

Alter ~/.bashrc to remove old condo init

• Log into your home ~/ folder on hpcnode1
  cd

• Make a copy of .bashr rc just in case
  cp ~/.bashrc Original_bashrc

• Open ~/.bashrc with vi or a ssh text editor
  vi ~/.bashrc

• Delete this block from bashrc.

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/opt/anaconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
eval "$__conda_setup"
else
if [ -f "/opt/anaconda3/etc/profile.d/conda.sh" ]; then
. "/opt/anaconda3/etc/profile.d/conda.sh"
else
export PATH="/opt/anaconda3/bin:$PATH"
fi
fi
unset __conda_setup
# <<< conda initialize <<<

• Use vi or a text editor over ssh.
  • Navigate to lines and delete them (press dd in vi to delete each line)
• Exit and save
  • In vi type :x! To quit and save you can type :q! To quit without save

Log out of hpcnode1 and log back in You should see that you are no longer in conda.

Initialize to new condo

• You can check what condo version you are using by typing

conda —version

• If you should condo 2024 - great! Otherwise contact Rob

• Initialize new condo

conda init

• Log out of hpcnode1 and log back in (this re reads your bashrc and resets your bash variables)

Fix the notWritable problem

Make a ~/.condarc if you do not have one.

vi ~/.condarc

Add this block if it isn’t already there envs_dirs: 
- ~/.conda/envs 
- /opt/anaconda/envs pkgs_dirs: 
- ~/.conda/pkgs

This will explicitly tell Conda that environments might be global or in HOME but that pkgs will be only in HOME, where everyone has read/write permissions

You should be done. Feel free to use your old envs but I made a new one to avoid possible headaches See Getting started w Conda
