Scenario Initialisation Failure (Outdated usage of dvc run) #18

Closed suryaavala closed 3 years ago

suryaavala commented 3 years ago

Issue

Scenarios Pipelines and Experiments and Metrics are not being initialized properly (see Output below) due to outdated use of dvc run command, especially with the use of -f flag.

Example: refer to line #56 in Pipeline Preparation Script

dvc run \
       -f prepare.dvc \
       -d src/prepare.py \
       -d data/data.xml \
       -o data/prepared \
       python \
           src/prepare.py \
           data/data.xml

According to Getting Started Docs, this should have been

dvc run \
       -n prepare \
       -p prepare.seed,prepare.split \
       -d src/prepare.py \
       -d data/data.xml \
       -o data/prepared \
       python \
           src/prepare.py \
           data/data.xml

Fix

Go through these scenarios and update them if they have diverged from the Getting Started Docs (I am happy to make these changes and submit a PR - started working on it already)
