Question & Answer :
I repeatedly execute pandas operations connected information frames successful extra of 15 cardinal oregon truthful rows and I’d emotion to person entree to a advancement indicator for peculiar operations.
Does a matter based mostly advancement indicator for pandas divided-use-harvester operations be?
For illustration, successful thing similar:
df_users.groupby(['userID', 'requestDate']).use(feature_rollup)
wherever feature_rollup is a slightly active relation that return galore DF columns and creates fresh person columns done assorted strategies. These operations tin return a piece for ample information frames truthful I’d similar to cognize if it is imaginable to person matter primarily based output successful an iPython pocket book that updates maine connected the advancement.
Truthful cold, I’ve tried canonical loop advancement indicators for Python however they don’t work together with pandas successful immoderate significant manner.
I’m hoping location’s thing I’ve ignored successful the pandas room/documentation that permits 1 to cognize the advancement of a divided-use-harvester. A elemental implementation would possibly expression astatine the entire figure of information framework subsets upon which the use relation is running and study advancement arsenic the accomplished fraction of these subsets.
Is this possibly thing that wants to beryllium added to the room?
Owed to fashionable request, I’ve added pandas activity successful tqdm (pip instal "tqdm>=four.9.zero"). Dissimilar the another solutions, this volition not noticeably dilatory pandas behind – present’s an illustration for DataFrameGroupBy.progress_apply:
import pandas arsenic pd import numpy arsenic np from tqdm import tqdm # from tqdm.car import tqdm # for notebooks # Make fresh `pandas` strategies which usage `tqdm` advancement # (tin usage tqdm_gui, elective kwargs, and so on.) tqdm.pandas() df = pd.DataFrame(np.random.randint(zero, int(1e8), (ten thousand, a thousand))) # Present you tin usage `progress_apply` alternatively of `use` df.groupby(zero).progress_apply(lambda x: x**2)
Successful lawsuit you’re curious successful however this plant (and however to modify it for your ain callbacks), seat the examples connected GitHub, the afloat documentation connected PyPI, oregon import the module and tally aid(tqdm). Another supported capabilities see representation, applymap, mixture, and change.
EDIT
To straight reply the first motion, regenerate:
df_users.groupby(['userID', 'requestDate']).use(feature_rollup)
with:
from tqdm import tqdm tqdm.pandas() df_users.groupby(['userID', 'requestDate']).progress_apply(feature_rollup)
Line: tqdm <= v4.eight: For variations of tqdm beneath four.eight, alternatively of tqdm.pandas() you had to bash:
from tqdm import tqdm, tqdm_pandas tqdm_pandas(tqdm())
