    deps:
    - data/train.csv
    - src/train.py
    params:
    - data_split
    - train
    outs:
    - models/model.joblib

  evaluate:
    cmd: python src/evaluate.py --config=params.yaml
    deps:
    - data/classes.json
    - data/test.csv
    - models/model.joblib
    - src/evaluate.py
    params:
    - data_load
    - data_split
    - evaluate
    - train
