[Bug]: The truth value of a DataFrame is ambiguous.

[DRMPN]

Expected Behavior

Pipeline starts tuning with provided input data.

tuned_pipiline = auto_model.tune(input_data=orig_data, timeout=10, cv_folds=10, n_jobs=4)

Current Behavior

ValueError: The truth value of a DataFrame is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().

Possible Solution

Change line 230 in fedot/api/main.py to the following:

if not input_data: 
    input_data = self.train_data

Steps to Reproduce

Data from https://www.kaggle.com/competitions/playground-series-s4e6

from fedot.api.main import Fedot
import pandas as pd

train = pd.read_csv("/automl-june/playground-series-s4e6/train.csv")
test = pd.read_csv("/automl-june/playground-series-s4e6/test.csv")

train.drop(columns=["id"], inplace=True)
test.drop(columns=["id"], inplace=True)

auto_model = Fedot(
    problem="classification",
    metric=["precision", "accuracy", "roc_auc"],
    preset="best_quality",
    with_tuning=True,
    timeout=60,
    cv_folds=10,
    seed=42,
    n_jobs=1,
    logging_level=10,
    use_pipelines_cache=False,
    use_auto_preprocessing=False,
)

auto_model.fit(features=train, target="Target")

prediction = auto_model.predict(features=test, save_predictions=True)

print(auto_model.return_report().head(10))

print(auto_model.get_metrics(target=train.Target))

tuned_pipiline = auto_model.tune(input_data=train, timeout=10, cv_folds=10, n_jobs=4)
