# Classification # Classification
**_NOTE_** autosklearn only will run in linux (feb 26, 2022) **_NOTE_**
Example coming from [here](https://automl.github.io/auto-sklearn/master/examples/20_basic/example_classification.html#sphx-glr-examples-20-basic-example-classification-py) The module `autosklearn` will only run in Linux environments, such as Google Collab or Jupyter Hub. Attempting to run this notebook will fail if you are not in a Linux environment.

**Classification doesn't work with current version of scipy/github and requires different packages/updates to run notebook** Example coming from [here](https://automl.github.io/auto-sklearn/master/examples/20_basic/example_classification.html#sphx-glr-examples-20-basic-example-classification-py)
- Note from professor Colbry: Notebook can't be fixed in classtime, write note of what needs to be fixed and push to gitlab as is.
