Extract Input parameters from "mxnet" model

Question

I have saved the model using

mx.model.save(model = fit_dl, prefix = "model", iteration = 10)

and loaded later

fit <- mx.model.load(prefix = "model", iteration = 10)

Now, using object fit, I want to extract the input features (column names of train data). How to do that

Hi, Shiv,

I don't this is possible since we never store this information in the model.
