Ipython Notebook - Python3 Not Found After Uninstalling Anaconda3 For Anaconda

I uninstalled Anaconda 2.3 with Python 3.4.3 and then installed the same Anaconda version with Python 2.7.10. When I open a notebook via $ ipython notebook 'Example Notebook.ipynb

Solution 1:

You can install several python versions alongside each other. Just create another environment (replace "all my packages" with the names of the packages).

conda create--name mypy_27 python = 2.7

or

conda create--name mypy_34 python = 3.4

afterwards you can activate the environments by typing

source activate mypy_34

if you then do

conda install "all your packages"

you install the desired packages in the active environment.

You can do much more.
