Use conda environment in Jupyter Notebook

Question

I am running Anaconda on windows 10 and using Jupyter Notebook for my Machine Learning projects.

I recently became aware of virtual environments in conda.

I created a virtual environment in conda using following command

conda create -n test1

activated the environment

activate test1

installed environment in ipykernel (not sure correct terminology is used)

python -m ipykernel install --user --name test1

now the environment test1 is visible in jupyter notebook but when i start it I am getting kernel starting... please wait message.

here are some snippets.

also in jupyter prompt (again not sure about the terms) i am getting following error

[I 21:08:24.924 NotebookApp] Creating new notebook in /MachineLearning/ImageProcessing

All I want to do is use newly created environment in jupyter notebook.

This really is a duplicate of "Conda environments not showing up in Jupyter Notebook" Unfortunately, there are many misinformed answers on that thread, but I can recommend this answer specifically as a proper route. — merv
@merv I followed the steps mentioned in the answer provided in your comments. I am confused though. Do I need to activate a particular environment everytime I want to do some development in jupyter using that environment? — Stolaine
Also I want to know what this NotImplementedError means. Is there any wrong step which I am performing? Why it is not working? — Stolaine
no you always activate and launch Jupyter from the env with Jupyter then you can choose the env you want to use as a kernel in the notebook — merv

Please try the following steps:

source activate test1
conda install ipykernel
ipython kernel install --name test1 --user
