问使用特定的虚拟环境在Jupyter notebook中执行Python脚本

EN

$pip install virtualenvwrapper
$mkvirtualenv -p python2 py2env 
$workon py2env

# This will activate virtualenv

(py2env)$ 

# Then install jupyter within the active virtualenv
(py2env)$ pip install jupyter

# jupyter comes with ipykernel, but somehow you manage to get an error due to ipykernel, then for reference ipykernel package can be installed using:
(py2env)$ pip install ipykernel

(py2env)$ python -m ipykernel install --user --name py2env --display-name "Python2 (py2env)"

(py2env)$ jupyter notebook
# or
#$ jupyter notebook

mkvirtualenv jupyter2
workon jupyter2
(jupyter2) pip install jupyter
(jupyter2) ipython kernel install --name "jupyter2_Python_2" --user

mkvirtualenv -p /usr/bin/python3 jupyter3
// this uses python3 as default python in virtualenv
workon jupyter3
(jupyter3) pip install jupyter
(jupyter3) ipython kernel install --name "jupyter3_Python_3" --user
