I think I have a misunderstanding regarding Dask's compute() method.Basically, when preprocessing data--renaming columns, changing to category or int, dropping columns, grouping by--do I need to call compute()?When calculating value_counts(), mean(), sum(), I believe I do need to call compute().But when using head() and len() I do not need to call compute()So how do I know when to call compute()?  Thank you!
On which methods do you need to call compute() when using Dask?
python;scikit learn;pandas
