Hi TMVA Experts,
I have a model trained using TMVA PyKeras that I need to apply within an analysis framework where tensorflow/keras are unavailable. Therefore, I’m trying to convert the model to a standard JSON format with the lwtnn keras2json converter. One of the things I need to do is make a variables.json file (templates are shown here: https://github.com/lwtnn/lwtnn/wiki/Keras-Converter) listing input variables together with parameters used for normalizing them in the training - offset and scale values. I think it should be possible to access these values using TMVA outputs (class.C and weights.xml files), but I cannot figure out how. What would be the easiest way to do this?
