Intersystems Iris - embedded python

#InterSystems IRIS #Embedded Python

Hello,

I'm starting testing embedded python and external libraries.

When I try to use the win32api-library I get the following error :

<THROW> *%Exception.PythonException  230 ^^0^ <class 'ModuleNotFoundError'>: No module named 'win32api' -

This is my code :

ClassMethod CreateDocument(path As %String) [ Language = python ]
{
import win32api

...
}
 

The librarie is visible in C:\InterSystems\IRIS\mgr\python\win32.

Am I doing something wrong ?

Regards,

Kurt Hofman,

1. Try running:

 cd <IRIS>\bin
 ./irispython "C:\InterSystems\IRIS\lib\python\Scripts\pywin32_postinstall.py" -install

It might fix your error.

If that does not help, add win32 folder to path explitictly and try import again:

import sys
sys.path.append("<IRIS>\Mgr\python\win32")
import win32api

There is no C:\InterSystems\IRIS\lib\python\Scripts\pywin32_postinstall.py

I get this error :

PS C:\Users\kurthofman> C:\InterSystems\IRIS\bin\irispip install --target C:\InterSystems\IRIS\mgr\python win32api
ERROR: Could not find a version that satisfies the requirement win32api (from versions: none)

Looks like there are some restrictions while installing win32api with pip
Try with pypiwin32 module as below: 
C:\Users\kurthofman> C:\InterSystems\IRIS\bin\irispip install --target C:\InterSystems\IRIS\mgr\python pypiwin32

I installed pypiwin32

ClassMethod Test() [ Language = python ]
{
import win32api

}

Hello @Kurt Hofman ,

I experienced a similar problem the last week while testing a library.

To solve it, I created the PYTHONPATH system environment variable with C:\InterSystems\IRISHealth\lib\python\Lib\site-packages\win32;C:\InterSystems\IRISHealth\lib\python\Lib\site-packages\win32\lib.
IRIS need to be restarted to consider any change in an environment variable.

Check If pythoncom39.dll and pywintypes39.dll exist in the directory C:\InterSystems\IRISHealth\lib\python\Lib\site-packages\win32. If they don't exist, copy them. I don't remember the initial directory of these dll files (maybe C:\InterSystems\IRISHealth\mgr\python\pywin32_system32).

I'm a beginner in Python, so maybe a more simple and clean solution exists...

Hope this help.
