Frequently Asked Questions

My Mac computer automatically renames the Jupyter Notebooks to .txt files when downloading, which then cannot be opened in the browser. How do I get the original file format?.

Click on the file and replace the extension '.txt' with '.ipynb' in the file name. Now the file is visible in the Jupyter browser and can be opened by clicking on it.

The Jupyter notebooks give me long error messages. How do I deal with this?

Oftentimes, the error messages are very detailed. However, the crucial point is the last line, which usually contains a hint about missing python modules or undefined variables (e.g.: 'music' is not defined). Not infrequently there are also typos in the command code. With these hints it is easy to reconstruct which code cell was not executed or which command was typed wrong.
