Hi,
I am trying to use TMVA PyRandomForest. I am able to do the training,testing and evaluation smoothly,
However when I try to Evaluate MVA using TMVA::Reader I get following crash.
Info in <MMLResponse::LoadData>: Loaded data from /home/chinmay/MaceSIM-PROOF-TestData/Test5Deg/GammaPar.root/HParameters

I tried to change the directory and even tried to evaluate the MVA from the same directory that containes ‘.weights.xml’ file. It doesn’t work.
Please help.
