"arcpy module does not exist"

JeremiahNieves — Thu, 27 Dec 2012 23:13:32 GMT

Quick background of the hardware and software I'm using:
OS: Windows 7 64-bit
Arc Info 10.0
IDE: Wingware Python IDE 4.1.3
Python 2.6 (installed with ArcGIS) AND 2.7 are installed on my machine

I am compiling a script to create 3D lines connecting 3D point features based on a common field. These point features represent bus stops and ultimately I am creating a multi-modal transportation network model. The street level stops are called "real" and are in one file where as the elevated stops are referred to as "psuedo" and are grouped by the route number they are associated with (some service more than one route so there is overlap).
My main problem right now is that when I am debugging my script, the debugger keeps on saying that the arcpy module does not exist. I checked in command line with assoc and ftype to make sure that all .py file were associated with 2.6 and not 2.7. I tried to append the arcpy path using the sys module (see script) and it still said that arcpy did not exist. I can go through my computer and see the arcpy folder so I know it is there.
Any ideas?

A source outside the forum, a Mr. Callahan, assisted me with this problem. It turns out that Python 2.7 and the 2.7 Numpy and Scipy packages I had installed as well were interfering with the call to arcpy for some reason. Once I uninstalled Python 2.7 and the mentioned packages, I was able to call arcpy with no problem.
