How to set up and validate locally

How to set up and validate locally

1. Enable the feature flag

   echo "Feature.enable(:ml_experiment_tracking)" | bundle exec rails c

2. Create an Experiment and 10 candidates

   # Added variables
   user_id = 1
   project_id = 1
   
   exp = Ml::Experiment.create!(name: "Awesome Gitlab Experiment", user_id: user_id, project_id: project_id)
   10.times.each { |i| exp.candidates.create!(user_id: user_id, start_time: 0, name: "candidate_#{i}") }
   exp.candidates.each_with_index { |c, i| c.metrics.create!(name: "auc", value: i*0.1 , tracked_at: Time.zone.now, step: 1)} 
   exp.candidates.each_with_index { |c, i| c.metrics.create!(name: "accuracy", value: i* 0.1+0.1 , tracked_at: Time.zone.now, step: 1)} 
   exp.candidates.each { |c| c.params.create!(name: "algorithm", value: ["LogisticRegression", "DecisionTree"].sample )}

3. Navigate to <your project>/-/ml/experiments and click on "Awesome Gitlab Experiment". It should show the new UI.

4. Setting the query to 'balh' should show the empty state
