No checkpoint specified

When I run the command (to create dataset)

`for alpha in {0.0,1.0}; do python3 scripts/create_dataset.py --save_dir=$HOME/tmp/ --load_dir=$HOME/tmp/CartPole-v0 --env_name=cartpole--num_trajectory=400 --max_trajectory_length=250 --alpha=$alpha --tabular_obs=0; done`

It runs into error with the following information:

`AssertionError: No checkpoint specified (save_path=None); nothing is being restored.`

Any idea?

Start with scripts/create_dataset.py and reproduce the command shown for CartPole-v0. Trace where the missing save_path assertion is reached and check how the command-line options are used. Done means the dataset command either runs with the documented inputs or clearly reports the required checkpoint configuration.
