JupyterLab notebook kernel crashes when using AutoSklearnClassifier

See original GitHub issue

Describe the bug

I’m running JupyterLab and am using AutoSklearnClassifier in a notebook cell. If I execute the cell I get an error and the notebook kernel crashes.

To Reproduce

Open JupyterLab.

2 . Paste this code into a notebook cell.

model = autosklearn.classification.AutoSklearnClassifier(
    time_left_for_this_task=5*60,  # 5 Minuten Gesamtlaufzeit
    per_run_time_limit=30,  # Hyperparameter pro Algorithmus 30 Sekunden optimieren
    memory_limit=4*1024,  # Freeze von Notebook verhindern
    n_jobs=8,  # auf 8 CPU-Cores laufen lassen
    ensemble_size=1,  # Overfitting vermeiden (ensemble_size + initial_configurations_via_metalearning)
    initial_configurations_via_metalearning=0,  # Overfitting vermeiden (ensemble_size + initial_configurations_via_metalearning)
)
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.25, random_state=1)

model.fit(X_train, y_train)
y_hat = model.predict(X_test)
mae = mean_absolute_error(y_test, y_hat)
mae

Execute the cell.

Expected behavior

Code executed, JupyterLab notebook not crashing.

Actual behavior, stacktrace or logfile

Output in output cell:

/home/florian/gitlab/data-processing/.venv/lib/python3.8/site-packages/pyparsing.py:3190: FutureWarning: Possible set intersection at position 3
  self.re = re.compile(self.reString)

The notebook kernel crashes:

Kernel Restarting

The kernel for notebooks/honey.ipynb appears to have died. It will restart automatically.

Dear all, we have finally pushed wheels of the pyrfr package to pypi so this should no longer be an issue (on platforms that support the manylinux2010 and manylinux2014 tag). If you find any issues with those wheels, please reopen this issue.

I’ve setup Ubuntu 20.04 for WSL2 recently. With Python 3.8.5 and swig 4.0.1-5build1 I could install auto-sklearn 0.12.3 without trouble.
