rectools.metrics.calc_metrics method does not work

rectools.metrics.calc_metrics method does not work when trying to run it i got empty result.

code that i tried to run :

from rectools import Columns
from rectools.metrics import Accuracy, NDCG
reco = pd.DataFrame(
{
Columns.User: [1, 1, 2, 2, 3, 3, 3, 3, 4, 4, 4],
Columns.Item: [7, 8, 1, 2, 1, 2, 3, 4, 1, 2, 3],
Columns.Rank: [1, 2, 1, 2, 1, 2, 3, 4, 1, 2, 3],
}
)
interactions = pd.DataFrame(
{
Columns.User: [1, 1, 2, 3, 3, 3, 4, 4, 4],
Columns.Item: [1, 2, 1, 1, 3, 4, 1, 2, 3],
Columns.Datetime: [1, 1, 1, 1, 1, 2, 2, 2, 2],
}
)
split_dt = 2
df_train = interactions.loc[interactions[Columns.Datetime] < split_dt]
df_test = interactions.loc[interactions[Columns.Datetime] >= split_dt]
metrics = {
'ndcg@1': NDCG(k=1),
'accuracy@1': Accuracy(k=1)
}
calc_metrics(
metrics,
reco=reco,
interactions=df_test,
prev_interactions=df_train,
catalog=df_train[Columns.Item].unique()
)

Output:
{}

Hi @OmarovSayan, I reproduced your code (added only missed imports from rectools.metrics import calc_metrics and import pandas as pd. It works for me

Can you please say your OS, Python version and packages (pandas and rectools) versions?
