Background python parser crashes importing sklearn.cluster in VS2017

[jaybo]

Environment data

• PTVSD version: 4.2.0 and 4.2.4
• OS and version: Windows 10, 1607, 14393.2670
• Python version (& distribution if applicable, e.g. Anaconda): Anaconda 3.6.8
• Using VS Code or Visual Studio: VS2017, 15.9.7

Actual behavior

Background code parser crashes importing sklearn.cluster.

Expected behavior

The background code parser should never crash. On PTVSD 4.2.0 If I dismiss the crash dialog, it will reappear after about one minute, presumably when the background parser is auto-restarted.

Steps to reproduce:

1. pip install scikit-learn

2. Load a python script which can be as simple as:

from sklearn.cluster import KMeans

3. Wait a moment, then:
   

4. The program will run successfully.

Could you clarify the steps to reproduce - is there another step there to launch it somehow, e.g. F5? Or by "load", do you mean just opening it in the editor and then waiting?

[jaybo]

Just opening it in the editor and then waiting a moment will trigger the problem.
