iPython Error

[Vincent Jeanselme]

Hello all,

If you have the following error when you use ipython on the server (or 
if your jupyter notebooks are much slower than before):

    [TerminalIPythonApp] ERROR | Failed to open SQLite history
    /home/scratch/$USER/.ipython/ipython_hist.sqlite (unable to open
    database file).

You need first to create a ipython config file : ipython profile create
And then to add in the created file (usually 
/zfsauton/home/$USER/.ipython/profile_default/ipython_kernel_config.py) 
the following line:

    c.HistoryManager.hist_file="/home/scratch/USER/.ipython_hist.sqlite"

This way ipython will write its history on the local disk,

Vincent
