Importing Pandas gives error AttributeError module pandas has no attribute core in iPython Notebook

Question

I am running a iPython notebook via the Anaconda Navigator app  version 1 1 0   When I want to import pandas it gives me a strange error  I thought the Anaconda app included the pandas package   --------------------------------------------------------------------------- AttributeError                            Traceback  most recent call last   lt ipython-input-4-af55e7023913 gt  in  lt module gt    ---- gt  1 import pandas as pd   Users bertcarremans anaconda lib python3 5 site-packages pandas   init   py in  lt module gt     37 import pandas core config init  38  --- gt  39 from pandas core api import    40 from pandas sparse api import    41 from pandas stats api import     Users bertcarremans anaconda lib python3 5 site-packages pandas core api py in  lt module gt      8 from pandas core common import isnull  notnull   9 from pandas core categorical import Categorical --- gt  10 from pandas core groupby import Grouper  11 from pandas core format import set eng float format  12 from pandas core index import  Index  CategoricalIndex  Int64Index    Users bertcarremans anaconda lib python3 5 site-packages pandas core groupby py in  lt module gt     16                               DataError  SpecificationError   17 from pandas core categorical import Categorical --- gt  18 from pandas core frame import DataFrame  19 from pandas core generic import NDFrame  20 from pandas core index import  Index  MultiIndex  CategoricalIndex    Users bertcarremans anaconda lib python3 5 site-packages pandas core frame py in  lt module gt     37                                    create block manager from arrays   38                                    create block manager from blocks  --- gt  39 from pandas core series import Series  40 from pandas core categorical import Categorical  41 import pandas computation expressions as expressions   Users bertcarremans anaconda lib python3 5 site-packages pandas core series py in  lt module gt     33 from pandas core internals import SingleBlockManager  34 from pandas core categorical import Categorical  CategoricalAccessor --- gt  35 import pandas core strings as strings  36 from pandas tseries common import  maybe to datetimelike   37                                    CombinedDatetimelikeProperties   AttributeError  module  pandas  has no attribute  core

I had exact issue and here is how I fixed:

I found out that I had first installed Keras then installed pandas in my virtual env. When you install keras, pandas is shipped with it. Do not need to pip install pandas.

I tested this hypothesis by creating new virtual environment and wala... pandas appeared without me installing it. Thus I came to the conclusion that pandas is automatically installed when you pip install keras.

Apparently the error I got when trying to import pandas for the first time was ValueError  unknown locale  UTF-8  Trying to import again afterwards  gave another error as described in my question above   I found the solution to solve the ValueError on IPython Notebook locale error  After updating my bash profile  the error AttributeError  module  pandas  has no attribute  core  did not appear anymore

yes  the Anaconda distribution includes pandas  type  conda list   to get a list of the packages installed

There is an other weird reason this happens  If you have a file called pandas py or a directory called pandas in the same or nested levels  that library is used instead and fails to work  Rename the folder and restart the env and it started working  Faced this

There s this bug in the latest version of pandas  pandas 0 23  that gives you an error on importing pandas   But this can be easily fixed by installing an earlier version of pandas  pandas 0 22  using the command pip install pandas  0 22 on Windows Command Prompt

I have just solved this problem  Recently  I changed my language setting of my MacBook from English-UK to Chinese  And I suppose that setting will also change the setting in the  locale   Becuase when I switched back  I found that the setting of locale had been changed again  and I am fine to import the pandas again    So if you have changed the language setting recently  you may worth to have a try change it back

You are getting this is because you are using a Anaconda distribution of Jupyter notebook  So just do conda install pandas restart your jupyter notebook and rerun your cell  It should work   If you are trying this on a Virtual Env try this   conda create -n name of my env python This will create a minimal environment with only Python installed in it  To put your self inside this environment run    2 source activate name of my env On Windows the command is  activate name of my env The final step required is to install pandas  This can be done with the following command   conda install pandas To install a specific pandas version   conda install pandas 0 20 3  To install other packages  IPython for example   conda install ipython To install the full Anaconda distribution   conda install anaconda  If you need packages that are available to pip but not conda  then install pip  and then use pip to install those packages   conda install pip  pip install django  Installing from PyPI pandas can be installed via pip from PyPI   pip install pandas Installing with ActivePython  Hope this helps

I got this from using the Anaconda default environment instead of my custom one with pandas installed   Changing to the right environment and reopening the Jupyter notebooks did not fix this for me  python 3 7  pandas 0 23 0    Restarting Anaconda did

Have you tried turning it off and on again    Roy of The IT crowd   This happened to me today  which is why I ended up to this page  Seeing that error was weird since  recently  I have not made any changes in my Python environment  Interestingly  I observed that if I open a new notebook and import pandas I would not get the same error message  So  I did shutdown the troublesome notebook and started it again and voila it is working again   Even though this solved the problem  at least for me   I cannot readily come up with an explanation as to why it happened in the first place

I had a similar issue since I installed pandas using python -m pip install pandas --upgrade --user which installed a conflicting version in my user python packages directory  masking the Anaconda installed version that other dependencies relied upon   conda list   grep pandas pandas    0 23 4  python -m pip list   grep pandas pandas    0 24 0   So uninstalling the user directory masked version cleaned up the issue for me   python -m pip uninstall pandas   For reference all possible python packages are installed in the directories listed from this command   python -m site   Might be worth iterating through these and checking for duplicates   Edit  Since my original answer I learnt you can run   python -m pip list -v   And it shows the directory the library is installed  This often shows whether the library you want is in a virtual environment  conda environment  user directory  system site packages etc
