Supercharge Your Jupyter Kernel With ipyflow

This is a pretty cool jupyter hack I learned recently.

While using Jupyter, you must have noticed that when you update a variable, all its dependent cells have to be manually re-executed.

Also, at times, isn't it difficult to determine the exact sequence of cell executions that generated an output?

This is tedious and can get time-consuming if the sequence of dependent cells is long.

To resolve this, try 𝐢𝐩𝐲𝐟𝐥𝐨𝐰. It is a supercharged kernel for jupyter, which tracks the relationship between cells and variables.

Thus, at any point, you can obtain the corresponding code to reconstruct any symbol.

What's more, its magic command enables an automatic recursive re-execution of dependent cells if a variable is updated.

As shown in the demo above, updating the variable x automatically triggers its dependent cells.

Do note that 𝐢𝐩𝐲𝐟𝐥𝐨𝐰 offers a different kernel from the default kernel in Jupyter. Thus, once you install 𝐢𝐩𝐲𝐟𝐥𝐨𝐰, select the following kernel while launching a new notebook:
