High IDL CPU Consumption #193

Closed MesoBolt closed 1 month ago

MesoBolt commented 9 months ago

Type: Bug

Hey there,

with the help of vscode "Help: Start Extension Bisect" I found out that the above extension seems to be the reason for a very high CPU consumption during idl. I did not run any script but just had ipynb files open and all my CPU cores were used at very high percentage for a longe time.

Kind regards Marius

play can you upload the notebook with the outputs as is

MesoBolt commented 9 months ago

I don't think I can do this because the notebook is pretty large and contains code and data I am not allowed to share open source.

But I can tell you that I am saving figures in for loops multiple times and use my own defined classes from a separate file, where I close all plot instances before entering a new cell with a loop to save figures. After every for loop the last saved figure is shown in the notebook.

Now I disabled this extension. Without having the CPU issue anymore, everything else still works, also the preview of the last saved images. What is this extension explicitly for?

This is responsible for rendering outputs, images and the like. And also widgets. Is it possible to remove the code, or replace it with some garbage string and replace the data (images/output) with some other random data/image, having a notebook would really help, else its not easy to identify the issue as we cannot replicate it at our end.

Closing this issue due to the fact that its been a few months since the last request for information.
