I have found that pandas v13.0 for Python 2.7 win32 works for most codes I have written in which I want to use both arcpy and pandas. I put that pandas version into the C:\Python27\ArcGIS10.2\Lib\site-packages directory. I tried other versions, but got miscellaneous errors when trying to run them.

I wrote a new code today, however, that manages to not work. It gives the error:

Access violation at address 1E0ACF39 in module 'python27.dll'. Read of address 9807D3AF.

with the following code: cond = dfDSS['OBSERVATION NAME']=='A413011CC1' dfDSS['GROUP'][cond]='HA273UTheads'

All the code before this to create dfDSS using pd.read_csv and inserting the column 'GROUP' with a value of 'other' everywhere is fine. Only when I try to reset the values using the conditional statement.

The code to this point was written in iPython Notebook using Anaconda, but I now want to do some arcpy stuff with it.

Any suggestions in getting the different versions of Python to work together are appreciated.
