While running experiment on AutoML, some errors occurs

Question

With Microsoft.ML.AutoML, when running an expreiment, some trials fails

"with exception of type System.OutOfMemoryException was thrown"
or
"with exception Arithmetic operation resulted in an overflow"

It only occurs with LightGbmRegression, I think. Without LightGgmRegression, trial never fails.

I have installed followings:

Microsoft.ML ver2.0.1
Microsoft.ML.AutoML ver0.20.1
Microsoft.ML.CpuMath ver2.0.1
Microsoft.ML.DataView ver2.0.1
Microsoft.ML.FastTree ver2.0.1
Microsoft.ML.LightGbm ver2.0.1
Microsoft.ML.OnnxRuntime ver2.0.1
Microsoft.ML.Recommender ver2.0.1
Microsoft.ML.TimeSeries ver2.0.1

I've gave a try on Previews but Microsoft.ML.AutoML does not run well on Previews.
