dask.dataframe.DataFrame.query
- DataFrame.query(expr, **kwargs)[source]
Filter dataframe with complex expression
Blocked version of pd.DataFrame.query
This is like the sequential version except that this will also happen in many threads. This may conflict with
numexpr
which will use multiple threads itself. We recommend that you setnumexpr
to use a single thread:import numexpr numexpr.set_num_threads(1)
