Memory Error: IOStream.Flush timed out

[acerock6]

Hi,

I was running a long session on Jupyter notebook. I mistakenly ran a function with no variables and the kernel got stuck. After a while, I saw the error: Memory Error., IOStream.Flush timed out
When I checked the OS task manager, there was sufficient memory present. What's weird is the kernel got stuck at a simple function call with no variables (something like do_something() )
Anyone has any idea how this might have occurred and what's the best way to avoid the same in the future (I lost 10-12 hours of work due to this error)
TIA

It happened to me also, while trying to see the output of a function that used multiprocessing.

I had the same issue when running a program in jupyter kernel that also was using multiprocessing module.

Same here. Jupyter was up for 4 days and I had to kill it by control-C.

Happened again. Jupyter notebook was running on AWS and I was using papermill to run notebooks.

Getting this issue when trying to import a module installed for local development ( pip install -e . )

after upgrading my Mac from Mojave to Catalina, I experience the same issue with a phrase of code that worked before.

I am having this problem as well. Anyone find a reason for this and how to address it? I was running a tsfresh job

from tsfresh import select_features

rel = select_features(extracted_features, y)

Hi,
I had the same problem and it was solved by restarting jupyter. Exit and then jupyter notebook command again.

Same problem here, instead of exit and relaunch the jupyter notebook, is there any way to fix it inside the program? thanks.
