Hi @kupruser,

The following is an example of what I did.

1. create train\_split.dvc with train\_split directory as output

> dvc run -f train\_split.dvc -d src/config/train\_split.json -d data/raw/train.csv.zip -o data/processed/train\_split python src/data/train\_split.py

1. create build\_features\_target\_enc with train\_split directory as input

> dvc run -f build\_features\_target\_enc.dvc -d src/config/build\_features\_target\_enc\_smooth.json -d data/processed/train\_split -d data/raw/test.csv.zip -o data/processed/target\_enc\_train\_features.csv.gz -o data/processed/target\_enc\_test\_features.csv.gz python src/features/build\_features\_target\_enc\_smooth.py

1. After doing some other work the files inside the train\_split directory had changed. I tried to rerun the pipeline expecting it to pick up on those changes and run itself from the build\_features\_target\_enc step.

> dvc repro build\_features\_target\_enc.dvc

but it said that there were no changes.
