IPython Notebook with multiple kernels and virtualenv

Explanations of how to install and use IPython Notebook with a venv and multiple virtualenv (one for Python 2 and one for Python 3).

Step-by-step installation

We run step-by-step and detail all the operations. A quicker, more concise guide can be found at the end of this gist.

Create virtualenv

We create first one venv for each version of Python.

mkvirtualenv -p /path/to/python2.7 venv-name

Fix for Git's CRLF fatal error

Fix for Git's CRLF fatal error

When a file has been created on a different system from the one you are using, some cariage returns characters cause problems when commiting to git. You can fix this problem by running one of the following commands, depending on your system.

sed -e 's/$/\r/' inputfile > outputfile                # UNIX to DOS  (adding CRs)
sed -e 's/\r$//' inputfile > outputfile                # DOS  to UNIX (removing CRs)
perl -pe 's/\r\n|\n|\r/\r\n/g' inputfile > outputfile  # Convert to DOS
perl -pe 's/\r\n|\n|\r/\n/g'   inputfile > outputfile  # Convert to UNIX (Mac OS X)
perl -pe 's/\r\n|\n|\r/\r/g'   inputfile > outputfile  # Convert to old Mac

Jupyter Notebook on remote server

How to use a remote Jupyter Notebook

On the remote server

Start the notebook in no-browser mode and specify a port (different from any other port on the server):

jupyter notebook --no-browser --port=[XXXX]

Optional: start the notebook in tmux or screen so that you can later close the terminal while be able to run the notebook (e.g. if you are runing a lon task).
