This Q&A mentioned similar problem https://stackoverflow.com/a/10741803/5088142

Can you please check which folders are mentioned in Spyder Tools/PYTHONPATH manager?

Also you can execute the following two lines in Spyder, and identify the location of pandas library:

import pandas 
print pandas.__file__

The output should be the path to pandas module Please add this path to Windows path (reference https://docs.python.org/2/using/windows.html )

Python:

import sys
sys.path.append('_location_of_python_lib_')

Windows CMD:

set PYTHONPATH=%PYTHONPATH%;C:\_location_of_python_lib_

Windows:

Simply add this path to your PYTHONPATH environment variable. To do this, go to Control Panel / System / Advanced / Environment variable, and in the "User variables" sections, check if you already have PYTHONPATH. If yes, select it and click "Edit", if not, click "New" to add it. Paths in PYTHONPATH should be separated with ";".

Answer 2

You should then install pandas using the windows interpreter.

Open Windows command prompt and type:

pip install pandas

or

easy_install pandas

depending on which package manager you use.
