integrating python(x,y) into ArcGIS 10.1 instead of python 2.7

[MathiasHaarmann]

Hi everyone,

I´d like to install ArcGIS 10.1 but using my already installed python(x,y) instead of taking further MB space. Someone knows how to accomplish this?

Thanks and regards,
Mathias

It should be possible since python(x,y) uses 2.7 and it includes numpy. I'm not sure if any other non-standard libraries are required by Arc. Since x,y is only 32-bit as far as I know you will not be able to use the new 64-bit geoprocessor which may hamper you in large operations.

As said, you'll need to ensure you have the following installed prior to installing ArcGIS:
-Python 2.7.2
-Numpy*
-Matplot lib*

*I forget version numbers, I think 1.6 for numpy..

If the ArcGIS Installer detects you have those installed, it wont install Python + modules.
