Description
We are trying to support algorithms written in python in QuantConnect/Lean (which is written in C#).
So far, we were able to accomplish that locally in Windows. However, we have to make it work in a docker container in order to launch algorithms in our servers, but we could't make pythonnet work in that environment.
Here are the steps we are following:
- Run a container:
docker run -it quantconnect/lean:foundation /bin/bash - Please checkout what system configuration quantconnect/lean:foundation has here.
- Install python:
apt-get update
apt-get install -y libglib2.0-dev python-all-dev python-pip git
pip install --upgrade pip && pip install pandas scipy numpy
- Install pythonnet
pip install git+https://github.com/pythonnet/pythonnet
After that, we ran the three winforms demos. All throw the same exception:
System.TypeInitializationException: The type initializer for 'System.Windows.Forms.WindowsFormsSynchronizationContext' threw an exception.

Finally, we ran the example of embedding Python in .NET from pythonnet README:
mcs /reference:Python.Runtime.dll test.cs && mono test.exe
that yields the following exception:
Unhandled Exception:
