pyt - can't get path of Toolbox in new release

[RositaBluhm]

Hello,

please help me. The Problem has shown with release of 10.2.1 and arcgis upgrade to Python 2.7.5.

Function:

class Toolbox(object):
    def __init__(self):
       sysPaths = sys.path

The result of sysPath is "['C:\\Windows\\system32\\python27.zip', u'c:\\program files (x86)\\arcgis\\desktop10.2\\arcpy', 'C:\\Program Files (x86)\\Python27\\ArcGIS10.2\\Lib', 'C:\\Program Files (x86)\\Python27\\ArcGIS10.2\\DLLs', 'C:\\Program Files (x86)\\Python27\\ArcGIS10.2\\Lib\\lib-tk', 'C:\\Windows\\System32', 'C:\\Program Files (x86)\\ArcGIS\\Desktop10.2\\bin', 'C:\\Program Files (x86)\\Python27\\ArcGIS10.2', 'C:\\Program Files (x86)\\Python27\\ArcGIS10.2\\lib\\site-packages', 'C:\\Program Files (x86)\\ArcGIS\\Desktop10.2\\arcpy', 'C:\\Program Files (x86)\\ArcGIS\\Desktop10.2\\ArcToolbox\\Scripts']" in the new release.

The former release of 10.2.0 shows this result and includes the Folder-path of the python Toolbox in the first position, which I need very much.
[u'C:\\...\\...\\Install', 'C:\\Windows\\system32\\python27.zip', u'c:\\program files (x86)\\arcgis\\desktop10.2\\arcpy', 'C:\\Python27\\ArcGIS10.2\\Lib', 'C:\\Python27\\ArcGIS10.2\\DLLs', 'C:\\Python27\\ArcGIS10.2\\Lib\\lib-tk', 'C:\\Windows\\system32', 'C:\\Program Files (x86)\\ArcGIS\\Desktop10.2\\bin', 'C:\\Python27\\ArcGIS10.2', 'C:\\Python27\\ArcGIS10.2\\lib\\site-packages', 'C:\\Program Files (x86)\\ArcGIS\\Desktop10.2\\arcpy', 'C:\\Program Files (x86)\\ArcGIS\\Desktop10.2\\ArcToolbox\\Scripts', 'C:\\Python27\\ArcGIS10.2\\lib\\site-packages\\win32', 'C:\\Python27\\ArcGIS10.2\\lib\\site-packages\\win32\\lib', 'C:\\Python27\\ArcGIS10.2\\lib\\site-packages\\Pythonwin']


What other way is there to get the path of the Toolbox??? Please help!

I'm not sure if this works with python toolbox, but I use it all the time for stand-alone scripts:

import sys
import os
currentScript=sys.argv[0]
scriptDir=os.path.dirname(currentScript)

Good luck!

[RositaBluhm]

Unfortunately "sys.argv" returns "['']". So that doesn't help.

Rosita,

In my own toolboxes, I have these lines:

local_path = os.path.abspath(os.path.dirname(__file__))
sys.path.insert(0, local_path)

That will get the path of the current file (in this case, the .pyt) and prepend it to Python's system path.

cheers,
Shaun

Thanks, Shaun. That works.

Anyhow, although it works I get an error-message through ArcCatalog which says:

Traceback (most recent call last):
  File "<string>", line 64, in __init__
NameError: global name '__file__' is not defined


Any idea?



Regards,
Rosita

If anyone is interested in the solution, this is how I fixed it:

I added the line with os.path.abspath... into a file "findingpath.pyc". I import the "findingpath" into the pyt-File and call the function that returns the path. It seems that it works properly.
