[jupyter-notebook] Stack in Kernel Starting

[Angel Cancio]

Hi, I write because I install Jupyter on my laptop:

➜  ~  lsb_release -d -r -c
Description:    Ubuntu 15.04
Release:    15.04
Codename:    vivid

➜  ~  python --version
Python 2.7.9
➜  ~  python2 --version
Python 2.7.9
➜  ~  python3 --version
Python 3.4.3


I can't use jupyter-notebook because it gets stuck in "Starting Kernel". I ran '--debug' and found only:

/usr/local/lib/python2.7/dist-packages/IPython/kernel/__init__.py:13: ShimWarning: The `IPython.kernel` package has been deprecated. You should import from ipykernel or jupyter_client instead.  "You should import from ipykernel or jupyter_client instead.", ShimWarning)

[W 18:37:15.980 NotebookApp] Timeout waiting for kernel_info reply from 6b524da6-4daf-456e-a38b-e745a00b681b


I erased and reinstalled: Jupyter, ipykernel, pyzqm, ipython ...Even I upgrade all packages by:

for i in $(pip freeze --local | grep -v '^\-e' | cut -d = -f 1); do sudo pip install -I --upgrade --no-deps --force-reinstall ${i} ; done


I Attach a file with all the packages from my system, versions, and debug output.

Any ideas!?

Regards

When I have weird problems like this, I usually make sure everything is ran in the same Python env by using `python -m pip` instead of `pip`.  Then to launch the notebook I do `python -m notebook`.  Also, you should be able to `pip install ipython[all]` to get everything all at once.

Actually what I finally did was clean everithing and install again

### Cleanning

for i in $(pip freeze --local | grep -v '^\-e' | cut -d = -f 1); do sudo pip uninstall -y ${i} ; done
for i in $(pip3 freeze --local | grep -v '^\-e' | cut -d = -f 1); do sudo pip3 uninstall -y ${i} ; done
sudo rm -rf /usr/local/lib/python2.7/site-packages
sudo rm -rf /usr/local/lib/python3.3/site-packages

### Installing
sudo apt-get install --reinstall python
sudo apt-get install --reinstall python3

sudo apt-get install --reinstall python3-setuptools
sudo apt-get install --reinstall python-setuptools
sudo apt-get install --reinstall python3-pip
sudo apt-get install --reinstall python-pip

 wget https://bootstrap.pypa.io/get-pip.py
 sudo python get-pip.py
 sudo python3 get-pip.py


## Install Jupyter
sudo -H pip install  jupyter
