Welcome to the Jupyter Notebook Early Adopter group

We have been experiencing a few issues with both the Jupyter and Streamlit implementations in Cognite. I will list them here, with a brief description, but am preparing a full document also (just waiting on the other devs to gather the other evidences).

Bugs – Jupyter:

“Ghost” characters: sometimes in markdown (text) cells, the characters “skip” and we cannot write text correctly. Some of our devs also experienced this bug in code output cells.

Semi-colon element: there is a <div> in the top Navigator (where the File, Edit, etc, options are) that blocks the interaction. It is a simple fix, and was already brought up to Cognite.

Bugs – Streamlit:

IDE Cursor jump: sometimes, while writing code into the development environment (IDE), when pressing tab (for indentation purposes), the cursor automatically jumps to End of File.

​@Hunter Beck 

Thank you for the reports ​@ibrahim.alsyed. I’ll file reports for the individual issues and provide some updates/status later tonight or tomorrow. Regards, Lars

Thank you.

​@Lars Moastuen  any update?

Hey Ibrahim,

So the extra semi colon is fixed in staging, please verify at https://staging.fusion.cognite.com. We are looking into the ghost characters now.

I got the notebook and could reproduce the problem with the ghost character. I see that this is also happening in https://jupyter.org/try-jupyter/lab/, so this is currently a bug outside of Cognite’s control. We will report this to the JupyterLab team. Thanks!

Hey, ​@Anders Hafreager , thank you for your effort. I can confirm that, in staging.fusion.cognite.com, the semicolon is not there anymore. Thank you for you effort on this.

Regarding the other issue, with ghost characters we ran into this more than often. One thing that appears to solve this temporarily is to remove `\r` characters from the notebook raw file.
