Arcgis10: Python error : RuntimeError : method datasetType does not exist

XavierMauclaire — Tue, 01 Feb 2011 09:47:31 GMT

Hi
I develop python script with eclipse.
When i run the code under eclipse ou with the dos command line ), i get the error "function not found"...

This code runs well under the python console of arccatalog

I set the PYTHONPATH with the arcgis 10 bin an arccpy directories .. no issue !!

Please Help !!! je craque !!!

My code :

import arcpy

if __name__ == '__main__':
    zPath = "c:/test.shp"
    print"toto"
    pDesc = arcpy.Describe(zPath)
#    error here RuntimeError: DescribeData: Method DatasetType does not exist
    print pDesc.DatasetType

# and here
    pExtent = pDesc.Extent


# and here
    print "Extent of shape :\nXMin: %f, YMin: %f, \nXMax: %f, YMax: %f" % \
        (pExtent.XMin,pExtent.YMin,pExtent.XMax,pExtent.YMax)

# and here
    pSr = pDesc.spatialReference

    print pSr.name

Try setting your env.workspace

import arcpy
from arcpy import env

if __name__ == '__main__':
    env.workspace = 'c:/temp/python'

    zPath = "c:/temp/python/test.shp"
    print"toto"
    pDesc = arcpy.Describe(zPath)
    # error here RuntimeError: DescribeData: Method DatasetType does not exist
    print pDesc.DatasetType

    # and here
    pExtent = pDesc.Extent


    # and here
    print "Extent of shape :\nXMin: %f, YMin: %f, \nXMax: %f, YMax: %f" % \
    (pExtent.XMin,pExtent.YMin,pExtent.XMax,pExtent.YMax)

    # and here
    pSr = pDesc.spatialReference

    print pSr.name

You should get something like:
C:\Temp\Python>python test.py
toto
FeatureClass

XMin: 1727760.654081, YMin: 657671.252142,

Did you add/modify what I posted?

Primarly

from arcpy import env
env.workspace = 'c:/temp/python'
zPath = "c:/temp/python/test.shp"

Set to your environment.

Yes sir i did that and got the same result !

On the other hand i can get defaults describe attributes (baseName, file etc) but not other specific attributes.
if with the debuger i do a hasattr(pDesc, "datasetType"), the answer is false...
amazing isn't it ?

Then I don't know. Two things I would try:

1) Add C:\Python26\ArcGIS10.0 to your system path and execute the .PY the way I did.

2) Put your code in a folder that does not contain spaces. Something like C:\temp for testing. Make it simple until you can figure out what's throwing the error.

You don't have multiple versions of Python your box do you?

The Path variable is ok
I'm going to test your idea.
Thanks for all.
