I have calculated using dask by
dask
from dask import dataframe all_data = dataframe.read_csv(path) total_sum = all_data.account_balance.sum()
.compute() does indeed bring you a real number, as you can see in this example:
.compute()
In [18]: import dask.dataframe as dd In [19]: d = dd.from_pandas(pd.DataFrame({'a': [3,3,3,3]}), npartitions=2) In [20]: d.a.sum().compute() Out[20]: 12
