This PR is urgent because CI for our PRs will fail until there is a fix.
After scikit-learn/scikit-learn#22094, sklearn estimators will contain an additional key in their
__dict__
after loading, namely"__sklearn_pickle_version__"
. This causes our tests to fail, since they compare objects before and after loading.The quick solution is to pop the item in our tests if it exists and only compare the remaining items.
Should the sklearn change be amended, we should remove the fix from this PR. Progress is tracked here:
