That smells like the pickle file has been created with a different version of Pandas, and your currently installed Pandas doesn't have the pandas.core.indexesmodule that some of the data in the pickle requires.
这听起来像是使用不同版本的 Pandas 创建的 pickle 文件，而您当前安装的 Pandas 没有pandas.core.indexespickle 中的某些数据所需的模块。
Which version of Pandas are you using? Have you tried upgrading?
您使用的是哪个版本的 Pandas？你试过升级吗？
EDIT: Pandas 0.19.2 does not have that module:
编辑：Pandas 0.19.2 没有该模块：
$ pip install pandas==0.23.3
$ python
>>> import pandas.core.indexes as i
>>>
$ pip install pandas==0.19.2
$ python
>>> import pandas.core.indexes as i
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'pandas.core.indexes'

I would suggest using pandas pickle method to read .pk file.
我建议使用 pandas pickle 方法来读取 .pk 文件。
import _pickle as cPickle
with open('filename.pkl', 'rb') as fo:
dict = cPickle.load(fo, encoding='latin1')
see doc here. Pickle Read
请参阅此处的文档。泡菜阅读

The answer by @AKX made me realise that it was probably a version problem Pandas. However, I only needed to upgrade.
@AKX 的回答让我意识到这可能是 Pandas 的版本问题。但是，我只需要升级。
pip install pandas --upgrade
