pandas.DataFrame（）AttributeError:“Index”对象没有属性“\u ndarray\u值”

Question

在尝试生成列名为的空数据帧时，我刚刚开始遇到一个相当复杂的错误

import pandas as pd

pd.__version__
Out: '1.0.1'

allGeneLen = pd.DataFrame(columns = ["Sample", "geneLength"])

Traceback (most recent call last):

  File "<ipython-input-243-4783cb8742c4>", line 1, in <module>
    allGeneLen = pd.DataFrame(columns = ["Sample", "geneLength"])

    The array interface, return my values.

AttributeError: 'Index' object has no attribute '_ndarray_values'

我不知道为什么会发生这种情况，据我所知，这种情况不应该发生。 有人有什么见解吗
