We're happy to share that python libraries are now fully supported in QuantConnect. We've completely re-engineered the python stack to use PythonNet which acts as a bridge between Python and .NET enabling use of all your favorite libraries!

The vast majority of the API remains identical but there will be some gotcha's. If you find your python algorithm aren't working anymore you will need to do a little conversion work to get them into the new system. There are 30 examples of the new python net framework in github you can use as a reference.

We've been testing for about 6 months but there will likely be issues in the integration. If you find an issue please let us know through support: support@quantconnect.com 

Thanks Alex and Stefano for all their work!
