这段代码中出现了 `SettingWithCopyWarning` 警告，警告的原因是在对 DataFrame 进行切片操作之后，对切片对象进行了赋值操作，这可能会导致原 DataFrame 的值也被改变，进而导致错误的结果。建议使用 `.loc` 或 `.iloc` 进行切片并进行赋值操作，以避免这个警告的出现。你可以使用如下代码来避免这个警告：

if label == 1:
    final_data = pd.DataFrame({'class': final_data})
    data.loc[data['class'] == label, 'class'] = final_data['class']
