I'm trying to use Accord.Net for its Machine Learning classes. As I understand it from previous discussions it used to work.

However when I try to use any class from Accord I get the following error message:

Algorithm.Initialize() Error: Algorithm type was not found. Try re-building algorithm. Stack Trace: at QuantConnect.Lean.Engine.Setup.BacktestingSetupHandler.CreateAlgorithmInstance (System.String assemblyPath, QuantConnect.Language language) [0x00050] in <7af17d06d0024189b13a6534ef2d8473>:0

Did a environment variable get reset again?
