Hello, i got message that this notebook is invalid. I can not open it in jupyter.
Thanks for your help!

Edit: now I put the lines manually in jupyter but after loop #47 i got following message:

Can you fix it please? Thanks

You are right, I fixed it. I pasted the code instead of the raw text content of the Jupyter file.

Regarding your error: It works when I run it locally. Maybe it helps to run everything in one Jupyter. I splitted it to make it easier to implement in the Medium article. I uploaded the merged version here: https://gist.github.com/nickyreinert/5621d17d63efbbd68584246d20fe4d2f
