Extending geoprocessing through Python modules - toolbox not in arcpy!

Question

After having it suggested by Drew Flater and Ghislain Prince at the Esri UC, I am attempting to use the extending geoprocessing guidance to make a toolbox easily accessible to ArcMap and Python as a system toolbox, using distutils. I created a toolbox with a model in it, ran the distutil stuff (I even figured out to create an msi to install it silently!). I can run it from ArcMap. Here's my GP dialog Executing: Foo Start Time: Fri Sep 25 17:30:36 2015 Executing (Calculate Value): CalculateValue "chr(12)*3 + "Hello world" + chr(12)*3" # Variant Start Time: Fri Sep 25 17:30:36 2015 Value = Hello world Succeeded at Fri Sep 25 17:30:36 2015 (Elapsed Time: 0.08 seconds) Succeeded at Fri Sep 25 17:30:36 2015 (Elapsed Time: 0.09 seconds) All well and good. But I don't see in arcpy as promised. (I thought this would be available from arcpy without ImportToolbox) >>> arcpy.Foo_footbx() Runtime error Traceback (most recent call last): File "", line 1, in AttributeError: 'module' object has no attribute 'Foo_footbx' Am I doing something wrong or does this only work with pyt files? The guidance seems to imply tbx files should work too. I've attached a zip of my attempt. One thing not clear from the help - do I need to edit __init__.py or footbx.py? If so what goes there? footbx_example.zip

I can't get my toolbox to show up in the Systems Tools. I've tried to follow the instructions at extending-geoprocessing-through-python-modules very closely. The reason may be that we do not actually install our python framework via a python installer. Our Windows installer delivers the package as a hierarchy of folders and creates a .pth file in the python Lib/site-packages folder to "install" it. Setup.py has never existed. We've been doing it this way for some time now, but without an accompanying toolbox and tools. Does anyone have relevant experience or knowledge?

Keep us posted.  I dont use arcmap's python so I can't help.  I use pythonwin and pyscripter for 2.7.x and 3.4.x

of course everything is installed in the site-packages folder in python...The only other thing I can think of is if you have multiple versions of python and the correct path not being picked up.

I could buy that if I couldn't run the tool from ArcMap, but I can. The arcpy I'm using is the ArcMap python prompt so I really am mystified. I will open a support incident.

This would be pretty cool if I could figure out how to make it work. What I do now is just drop a our custom toolbox desktop install folder's ArcToolbox folder (using an msi) - which works, the toolbox shows up in the System Toolboxes, BUT my custom tools won't work from arcpy unless I import them with ImportToolbox.
