[KED-1454] reload_kedro magic script not working with jupyter

Description

I created a new kedro environment and ran kedro jupyter notebook to create a notebook. Then I execute the %reload_kedro command which gave the following error: 2020-02-22 09:45:31,139 - root - ERROR - Kedro appears not to be installed in your current environment or your current IPython session was not started in a valid Kedro project.

I also executed the kedro ipython command to get the following error: Traceback (most recent call last): File “/anaconda3/envs/future_sales/lib/python3.6/site-packages/prompt_toolkit/application/current.py”, line 6, in <module> from contextvars import ContextVar ModuleNotFoundError: No module named ‘contextvars’

@Francisco-Reveriano This worked for me:

%load_ext kedro.extras.extensions.ipython
%reload_kedro

@mzjp2 Hi thanks! It works like charm, will look at the release note before raising the question next time 🤣 May I ask does quantumblack provide any YouTube/learning channel for Kedro?

@oscartse68 We’re so glad that you’re all sorted out on this one. I have one question and recommendation for you as a follow-up to this question you’ve asked.

My question is, “Why would you like to see a YouTube or video-based learning channel for Kedro?”

And then on that I would definitely recommend checking out the DataEngineerOne series on YouTube. It’s a series of Kedro tutorials on different functionality done by a super user of Kedro.
