How perform train test split in pipeline

[sagarshankar]

I am trying to use one train test split in my pipeline in order to cross validate on my model on test data. I am trying to figure out where in the pipeline construction should that step occur? How would you incorporate splitting the dataset in the pipeline? Also, I am currently getting error when I reference "d3m.primitives.tods.evaluation.kfold_dataset_split". It is telling me there are not enough arguments specified for the primitive.
