Issue
I'm trying to use a Jupyter Notebook in a virtual environment.
I have created a new virtualenv virtualenv ker12
+ activate + installed a specific version of keras or any other library.
also as mentioned in Using a virtualenv in an IPython notebook I did:
pip install ipykernel
and
python -m ipykernel install --user --name=my-virtualenv-name
when I run the notebook and write
! which jupyter the output is correct
/Users/myname/virtualenv/ker12/bin/python
but when I try to import a library, for example import keras there is an error.
ImportError: No module named keras
But from the other side when I write pip freeze | grep Keras
the output is:
Keras==1.2.0
UPDATE 1:
this problem is not related to Keras it occurs with any other library (for example pandas)
If I print os.path the output is following:
<'module 'posixpath' from /usr/local/Cellar/python/2.7.13/Frameworks/Python.framework/Versions/2.7/lib/python2.7/posixpath.pyc>
From a "command line python" the os.path looks correct
<'module 'posixpath' from '/Users/my_name/virtualenv/ker12/lib/python2.7/posixpath.pyc'>
UPDATE 2:
If I print sys.path from terminal and jupyter the output is also different:

Solution
the solution is to open jupyter notebook with following command:
~/virtualenv/my_venv_name/bin/jupyter-notebook
