I have installed Jupyter Notebook through Conda. Been using it for a month
without any issues. Suddenly today Jupyter Kernel started crashing and it
is failing to restart. One point to note. This opens without any problems:
http://localhost:8888/tree but crashes start to happen as soon as I open
any notebook (.ipynb file). (http://dpaste.com/3G7YQS4)
(gpd) [arnuld@arch64 geo]$ jupyter-notebook
