Unable to retrieve type info for Microsoft.ML dll

[AiTrading]

When I add Microsoft.ML dlls to NT Custom folder I get popup error messages like: “Unable to retrieve type info from ‘NinjaTrader.NinjaScript.AddOnBase’ from assembly ‘…’: Unable to load one or more of the requested types.” for the following dlls:

Microsoft.ML.StandardTrainers.dll
Microsoft.ML.LightGbm.dll
Microsoft.ML.Data.dll
Microsoft.ML.FastTree.dll

I tried to copy from VS project Release dir, I tried to use JetBrains dotPeek to copy all dependencies but nothing helps.

Thanks,
AiTrader

Hi AiTrading, thanks for posting.

The NinjaScript framework targets .NET 4.8 and ML.Net uses packages outside of .Net 4.8 desktop (namely .net core/standard). We have a feature request SFT-3124 requesting upgrading the target version to .net core/standard. I will add a vote to this for you.

Kind regards.
