Description

🐛 Bug

When running certain code it becomes impossible to interrupt the kernel until that code completes.

To Reproduce

import sklearn
# get large dataset on the order of 1e6 or 1e7
df = ...
sklearn.preprocessing.QuantileTransformer(subsample=1e7, n_quantiles=1e6).fit_transform(df)

Expected behavior

It should interrupt!

Additional context

That's just an example, I've seen it plenty of times over the last few weeks, usually for commands I'd expect to take a while but that I want to stop midway to tweak something. That just seemed like an easy to replicate example. Oddly enough, the QuantileTransformer will interrupt just fine when n_quantiles is an order of magnitude smaller.

Contributor guide

Research direction
Investigate how the kernel interrupt signal is handled during long running sklearn operations in the Kaggle Docker image. Check if the issue is related to IPython's interrupt handling or the Docker environment.
