cannot get pythonwin working with ArcGIS 10.6.1

RickHawkins — Thu, 21 Nov 2019 19:29:52 GMT

I am using ArcMap 10.6.1 and am trying to install and use pythonwin but i am not having much luck. What version of pythonwin should i be using and what version of python? When i try to enter import arcpy i get an error saying that module does not work. I am using pywin32-217.win32-py2.7.exe.

If i did not provide enough information please let me know. I just started learning python scripting for ArcGIS

You need the version for python 2.7.

You also have to use ArcMap's python interpreter... It sounds like you have a disconnect between the two

import sys
sys.executable‍‍

what does that report? and is it to the python that arcmp uses?

o you don't see something like this ?? (I can run pythonwin form ArcGIS pro, so the first part of the path isn't relevant... only the portion from … site-packages onwards is key

If memory serves, python for arcmap is installed in c:\python(version number etc)

i get the following: 'C:\\Python27\\Lib\\site-packages\\pythonwin\\Pythonwin.exe'

How do you use ArcMap's python interpreter? Right now i instatlled Python 2.7 and pywin 32 build 214. I tried the following code and get these errors. How do you get pythonwin to work with a current GIS document?

I haven't used arcmap in ages, but if memory serves there should be a

C:\pythonxx\ folder on you computer followed by something like arcmapxx.

pythonwin has to be installed in the site-packages folder in that path.

I suspect that you might have more than one python 2.7... uninstall one of them would be my recommendation and use the python that is installed in the aforementioned path.

So crankup File Explorer and see if you can locate in the root directory of C or in C:\Program Files

we all are... let me know if you can't find the path to python which has the arcmap version number in it

RickHawkins — Fri, 22 Nov 2019 18:03:47 GMT

This is the path to python.exe is: C:\Python27\ArcGIS10.6

When i try to run the simple code shown above i get "no module named numpy". How do i get around this?

Re: cannot get pythonwin working with ArcGIS 10.6.1

DanPatterson_Retired — Fri, 22 Nov 2019 19:25:26 GMT

Find and check the site-packages folder in that path and look for numpy. If it was installed, it should be there

RickHawkins — Fri, 22 Nov 2019 19:57:58 GMT

I have the following: C:\Python27\ArcGIS10.6\Lib\site-packages\numpy. It is installed so why do i get the error?

By the way, thanks for all of the help

DanPatterson_Retired — Fri, 22 Nov 2019 21:41:36 GMT

Rick....

Going totally image now... there is a common 'path' for spyder and for numpy

Try this

numpy will be in …\Lib\site-packages\numpy

pythonwin is in as shown

I'm wondering if you installed a second version of Python when you installed pythonwin. Its been some time, but I seem to recall a prompt from pythonwin at install time asking about using existing Python or a new install. From your traceback image above, I see the path 'C:\Python27\Lib\site-packages\pythonwin.....' which I don't think should be.

In your pythonwin Interactive Window, try the following and share the printout:

>>> import sys
>>> sys.path
['C:\\', 'C:\\Windows\\system32\\python27.zip', 'C:\\Python27\\ArcGIS10.6\\DLLs', 'C:\\Python27\\ArcGIS10.6\\lib', 'C:\\Python27\\ArcGIS10.6\\lib\\plat-win', 'C:\\Python27\\ArcGIS10.6\\lib\\lib-tk', 'C:\\Python27\\ArcGIS10.6\\Lib\\site-packages\\Pythonwin', 'C:\\Python27\\ArcGIS10.6', 'C:\\Python27\\ArcGIS10.6\\lib\\site-packages', 'C:\\Program Files (x86)\\ArcGIS\\Desktop10.6\\bin', 'C:\\Program Files (x86)\\ArcGIS\\Desktop10.6\\ArcPy', 'C:\\Program Files (x86)\\ArcGIS\\Desktop10.6\\ArcToolBox\\Scripts', 'C:\\Python27\\ArcGIS10.6\\lib\\site-packages\\win32', 'C:\\Python27\\ArcGIS10.6\\lib\\site-packages\\win32\\lib']
>>> sys.executable
'C:\\Python27\\ArcGIS10.6\\Lib\\site-packages\\Pythonwin\\Pythonwin.exe'

Outside of ArcMap, I don't think "Current" will work as a map document. Try using a full path/filename to your map document in line 5.

Except for this error, it appears that you have Pythonwin working, correct?
