假设pred是你的预测
它是numpy数组，然后你可以df。将preds作为Series合并到main df

import pandas as pd
import numpy as np

data = {'A': [1, 2, 3, 4], 'B': [5, 6, 7, 8]}
df = pd.DataFrame(data, index=[1, 2, 3, 4])

pred = np.array([0.1, 0.9, 0.5, 0.11])

series = pd.Series(pred, index=df.index, name='C')
result = df.merge(series, left_index=True, right_index=True)

print(result)
