ipykernel_launcher processes are consuming memory, Not able to kill

Asked 2022-Apr-03 at 18:03

What are these zombie ipykernel_launcher process in my machine, which are hogging to much memory:

This is output of htop command, but I ps for those processes,(to kill them) I do not see them as:

ps -ef|grep ipykernel

Not sure, how to get rid of these memory hogs!

...

ANSWER

Answered 2022-Apr-03 at 18:03

The reason why you're seeing all these processes in htop and not with ps is that htop is showing threads (see https://serverfault.com/questions/24198/why-does-htop-show-lots-of-apache2-processes-by-ps-aux-doesnt). Type "-H" inside htop to toggle showing threads.

Automatically stop idle kernels

Concerning Jupyter notebook processes in general: kernels are small computational engines and consume a lot of resources (mainly memory) even when they're not active. This is why one should encourage users to stop running kernels when they're not in use. The problem is that even if one closes a tab or the whole browser, the kernel keeps running, so one forgets about the kernels!

Since it's unlikely that users will shutdown their kernels, consider stopping idle kernels by configuring the parameter NotebookApp.shutdown_no_activity_timeoutInt in your Jupyter configuration file jupyter_notebook_config.py.

NotebookApp.shutdown_no_activity_timeoutInt.
Default: 0

Shut down the server after N seconds with no kernels or terminals running and no activity. This can be used together with culling idle kernels (MappingKernelManager.cull_idle_timeout) to shutdown the notebook server when it’s not in use. This is not precisely timed: it may shut down up to a minute later. 0 (the default) disables this automatic shutdown.

F2 rename variable doesn't work in vscode + jupyter notebook + python

Asked 2022-Mar-23 at 04:56

I can use the normal F2 rename variable functionality in regular python files in vscode. But not when editing python in a jupyter notebook.

When I press F2 on a variable in a jupyter notebook in vscode I get the familiar change variable window but when I press enter the variable is not changed and I get this error message:

No result. No result.

Is there a way to get the F2 change variable functionality to work in jupyter notebooks?

Notice that you put up a bug report in GitHub and see this issue: Renaming variables didn't work, the programmer replied:

Some language features are currently not supported in notebooks, but we are making plans now to hopefully bring more of those online soon.

So please wait for this feature.

Since you are initializing a tensorflow (version < 2) session with tfc.InteractiveSession() you might need to initialize all values before running your session by calling:

Asked 2022-Mar-17 at 07:09

I am finding it difficult to train the following model when using the 'Mobilenet_tranferLearning'. I am augmenting and loading the files from the directory using ImageDataGenerator and flow_from_directory method. What is interesting is that my code does not throw any errors when using InceptionV3, but does when I use 'Mobilenet_tranferLearning'. I would appreciate some pointers as I believe I am using the correct loss function 'categorical_crossentropy' which I have also defined in train_generator (class_mode='categorical').

Seems to be a bug in ipykernel 6.9.0 - options that worked for me:

upgrade to 6.9.1 (latest version as of 2022-02-22); e.g. via pip install ipykernel --upgrade
downgrade to 6.8.0 (if upgrading messes with other dependencies you might have); e.g. via pip install ipykernel==6.8.0
