I have a pickled item stored 2 years ago under Python 2and pandas version<0.17that I can’t understand how to open it. The element contains a dictionary with some pd.DataFrames parameters as the values assigned to the keys.
I was in Windows 7 at that time, and I can’t remember if I used a different encoding than the predefined one.
In Python3, after checking various combinations of open modes ('r','rb')for the file handler, pickle option fix_import=Trueand some other solutions that I found here, I couldn’t figure it out, so I decided to upload the file again in Python 2 and save it using the following code:
with open(path, 'rb') as handle:
cons = pickle.load(handle)
with open('cons.pickle','wb') as f:
pickle.dump(cons,f)
Also note that I can normally access the data framework in Python2
Now, in Python 3, I try to open it, and the following error occurs:
ImportError: no module named pandas.indexes
At this point, I understand that I have overcome the encoding problems between Python 2 and 3, but probably something is deprecated from the previous version of pandas that I used. My current version of pandas is in Python 2 - 0.19and in Python 3 0.20.
Should I load and “update” data frames in Python 2, and then migrate to Python 3 and how do I do this? I already tried to save the pickle again, but no luck .. Is there anything else causing the error, maybe?
