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 ";".

I added the path, but now i get a different error : ImportError : C extension : DLL load failed.....If u want to import pandas from source directory, you may need to run python setup.py build_ext....

How did you originally installed pandas? this link stackoverflow.com/q/30945272/5088142 mentioned similar problem in windows " There is a bug in older versions (of conda) where if you had updated pandas WHILE it was being used it didn't update correctly. Try closing all python processes, then conda remove pandas; conda install pandas"
Nitin
Initially it was installed with Anaconda by default and it is working fine with spyder. Do u still suggest to reinstall pandas ?
Yaron
Which path did you add?
Nitin
I have set PYTHONPATH to Appdata\local\Continuum\Anaconda3\lib\site-packages\

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.

Can't i somehow use the same libraries that are being used by spyder. spyder is able to find all the packages.

I think he is asking about a problem he encountered while running a python script from command line
