ImagingLSS on NERSC Jupyter Portal

This example will guide you setup imaginglss at NERSC with Jupyter.

https://jupyter.nersc.gov

This guide will not work on Cori or Edison. Refer to the documentation for using imaginglss in a Batch environment.

First time install

This will checkout the imaginglss source code to ~/imaginglss

If you'd like to put the code some other places, change the path.



In [2]:

    
%%bash 

cd ~

git clone https://github.com/desihub/imaginglss
cd imaginglss

/anaconda/bin/pip install --user -e .

You are using pip version 7.0.3, however version 8.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

Update

This will abandon all of your local changes!

%%bash 

cd ~/imaginglss

git stash
git pull

--user should either be a path to a local project or a VCS url beginning with svn+, git+, hg+, or bzr+

Head start for Developers

For developers, it is preferable to do updates with git pull from a true terminal window, or follow other standard git practice of merging in upstream changes. (e.g. git fetch)

The main development of imaginglss is done this way:

One terminal window connected to NERSC
One notebook connected to http://jupyter.nersc.gov
Write up some ideas in the notebook
git checkout -b mybigidea
implement it from the terminal window
Reload the notebook kernel and test the implementation
If it works, git add, git commit, git push, and file a Pull Request.
If it does not work, go to 'implement' step.
Wait till the feature is merged,
git checkout master; git branch -d mybigidea.

Reinstall

Usually not needed, but if things go severely wrong, try this.

%%bash

cd ~/imaginglss
/anaconda/bin/pip uninstall imaginglss
/anaconda/bin/pip install --user -e .
