Upgini 异常：日期列 `date` 具有字符串类型，但构造函数参数 `date_format` 为空

Question

I want to enrich my dataset with relevant public data by upgini python library.

%pip install -Uq upgini
import numpy as np
import pandas as pd
from upgini import FeaturesEnricher, SearchKey 

train_features=pd.read_csv("dataset.csv", sep=";")
train_target=train_features.target
train_features=train_features[['date']]
enricher = FeaturesEnricher(
    search_keys={"date": SearchKey.DATE}
)
enricher.fit(train_features, train_target)

And I get error:

Exception: Date column `date` has string type, but constructor argument `date_format` is empty.
Please, convert column to datetime type or pass date format implicitly

Could you help me to pass this problem?

Answer 1

from datetime import datetime

datetime.strptime(date_string, "%d %B, %Y").date()

Answer 2

upgini don't support string columns as SearchKey.Date. Try this as enricher description:

enricher = FeaturesEnricher(
    search_keys={"date": SearchKey.DATE}, 
    date_format="%Y-%d-%m"
)
