[FIXED] jupyter notebook and ipython don't take correct path after activating a conda environment

Issue

I have setup anaconda3 for multiple users in a lab workstation at /opt/anaconda3 so that other users don't have to set up a fresh anaconda3 install for themselves.

Then I created an environment called zud for my use. So currently, the workstation has two environments as listed below.

(base) zuddler@silp252-dl360:~$ conda env list
# conda environments:
#
zud                      /home/zuddler/.conda/envs/zud
base                  *  /opt/anaconda3

When I am activating my environment using conda activate zud, jupyter and ipython are not taking the correct path and thus I am not able to use manually installed libraries in my environment, so for an example, in my environment zud I installed python-igraph using conda install -c conda-forge python-igraph but cannot access it though jupyter notebook or ipython; they give ModuleNotFoundError.

Please go through the results of which commands on base and zud environments below.

For base:

(base) zuddler@silp252-dl360:~$ which python
/opt/anaconda3/bin/python
(base) zuddler@silp252-dl360:~$ which jupyter
/opt/anaconda3/bin/jupyter
(base) zuddler@silp252-dl360:~$ which ipython
/opt/anaconda3/bin/ipython
(base) zuddler@silp252-dl360:~$ which conda
/opt/anaconda3/bin/conda

and for zud:

(zud) zuddler@silp252-dl360:~$ which python
/home/zuddler/.conda/envs/zud/bin/python
(zud) zuddler@silp252-dl360:~$ which jupyter
/opt/anaconda3/bin/jupyter
(zud) zuddler@silp252-dl360:~$ which ipython
/opt/anaconda3/bin/ipython
(zud) zuddler@silp252-dl360:~$ which conda
/opt/anaconda3/condabin/conda

from the above results, I assume that upon activating zud, jupyter notebook and ipython are not taking the correct path.

Please suggest what's going on here and how to fix it.

In case any further details are needed, please let me know as well so that I can update my question accordingly.

Further, if my problem is answered somewhere, please let me know the link as I was not able to find its solution.

Solution

I observed the issue here! On changing the conda environment from base to zud, the ipython and jupyter utilities are still being used of the base env.

The main reason behind could be - In the zud env ipython and jupyter are not installed. Due to which, both are accessed from the base env. Try installing them in zud and see if the problem is fixed.
