Running Python script that is exported from model builder

yanma — Thu, 06 Mar 2014 15:41:48 GMT

So I???ve put up a simple model involving Kernel interpolation with barrier tool in ArcMap model builder and exported to Python script. (since the script is fairly short, I???ve pasted it down below.)

I feel the script is fine. But after I added to my toolbox in ArcMap and try to run it, some error pops up.

After a whole morning???s debugging, alas, I???ve finally managed to get ArcMap to crash every time I run my script...

I am guessing the problem is with the parameters I added to the script.

Could anyone explain a bit on how one should make sure a python script could be run from the toolbox and all parameters are called correctly.

More specifically: when I add parameters in ArcMap, given the python script that I already have, what display names should I put down for the parameters so that the software recognizes.

Any input is welcome and appreciated.

Can you try hard-coding the values in the script and see if that works? Also when hard-coding the values, just run the script through IDLE.

I'm not a Python expert, but I think the problem is in this line:

Output_geostatistical_layer = Input_features

You're giving the output geostatistical layer the same name as the input features. Try giving it a unique name or expose it as a parameter in your script tool.
