ModuleNotFoundError: No module named 'pandas.core.indexes'

问题

I wrote this code to load a dataset into a data frame. Dataset is given in a pickle file but it throws an error:

ModuleNotFoundError: No module named 'pandas.core.indexes'

import pickle
import pandas
dbfile = open(dataset loction,'rb')
df = pickle.load(dbfile)

I tried all the fixes given:

Updated the pandas
used df = pandas.read_picle(dataset location)

Tried installing pickle using pip but getting this error

C:\installs\WinPython-64bit-3.6.1.0Qt5\python-3.6.1.amd64>python -m pip install pickle
Collecting pickle
  Could not find a version that satisfies the requirement pickle (from versions: )

回答1:

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.indexes module that some of the data in the pickle requires.

Which version of Pandas are you using? Have you tried upgrading?

EDIT: Pandas 0.19.2 does not have that module:

$ 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.

import _pickle as cPickle
with open('filename.pkl', 'rb') as fo:
        dict = cPickle.load(fo, encoding='latin1’)

see doc here. Pickle Read

The answer by @AKX made me realise that it was probably a version problem Pandas. However, I only needed to upgrade.

pip install pandas --upgrade
