Warning when calling data_set.cache.load_data

[Jens Hedegaard Nielsen]

Taken from the auto_color_scale notebook (load_data is called by plot_dataset)

# store data in a separate db in order not to spam the actual measurement db
from qcodes.dataset import (
    initialise_or_create_database_at,
    new_data_set,
    new_experiment,
    plot_dataset,
)

initialise_or_create_database_at('../example.db')

# create an experiment for this tutorial
new_experiment(name='tutorial_auto_color_scale', sample_name="outliers")

# import methods for creating datasets with outliers:
from qcodes.tests.dataset_generators import dataset_with_outliers_generator

# create a new dataset with outliers
ds = dataset_with_outliers_generator(new_data_set('data_with_outliers'),
                                     low_outlier=-3, high_outlier=3,
                                     background_noise=False)

ds.cache._loaded_from_completed_ds

results in

Trying to mark a run completed that was already completed.
