train_label 没看明白，为什么要拼接呢 #827
Description
label_data = pd.read_csv("data/sales_train_evaluation.csv")
def get_label(target_day, predict_distance):
test_label = label_data["d_" + str(target_day)]
train_label = pd.DataFrame()
for day in range(target_day - training_data_days - predict_distance + 1, target_day - predict_distance + 1):
train_label = pd.concat([train_label, label_data["d_" + str(day)]], axis=0)
return train_label, test_label
train_label, test_label = get_label(target_day, predict_distance)
