Metaflow 2.0.0 executing PlayListFlow for user:minhtue

The next version of our playlist generator that uses the statistics
generated from 'Episode 02' to improve the title recommendations.

The flow performs the following steps:

1) Load the genre specific statistics from the MovieStatsFlow.
2) In parallel branches:
- A) Build a playlist from the top grossing films in the requested genre.
- B) Choose a random movie.
3) Join the two to create a movie playlist and display it.

Step start
    Use the Metaflow client to retrieve the latest successful run from our
    MovieStatsFlow and assign them as data artifacts in this flow.
    => bonus_movie, genre_movies

Step bonus_movie
    This step chooses a random title for a different movie genre.
    => join

Step genre_movies
    Select the top performing movies from the use specified genre.
    => join

Step join
    Join our parallel branches and merge results.
    => end

Step end
    Print out the playlist and bonus movie.

@minhtuev I believe that workflow 02 requires ‘pandas’ installed, Hence the error message:

import pandas 2019-12-04 13:43:05.177 [1575495784736229/start/1 (pid 46310)] ModuleNotFoundError: No module named 'pandas'
