I have a python script that uses the "requests" package. When I run the Universe program that calls the function I get the "requests" package not found. I then created another python script that calls the python script that contains the "requests" package and it works when I call that script from Universe.  I must have something wrong in my path setting when coming from Universe and it cannot find the "requests" package. If I run the python script in Linux the program executes perfectly. If I invoke python from universe and import requests it works fine and finds the requests package. Both scripts are in the default location /XDEMO/PP.

u2.pth

/usr/ibm/bin
/usr/ibm/XDEMO/PP

Universe program:

 SUBROUTINE SUB.BASEVEHICLE(VEHID,VEHOUT)

      CMD = "REINIT.PYTHON OFF"

      EXECUTE CMD


      ModuleName = "callbaseveh"
      FuncName = "getbasevehinf"

      RESULT = PyCallFunction(ModuleName , FuncName, VEHID)

      IF @PYEXCEPTIONTYPE NE '' THEN
         CRT "EXCEPTION TYPE IS " :@PYEXCEPTIONTYPE
         CRT "EXCEPTION MESSAGE IS " :@PYEXCEPTIONMSG
         CRT "EXCEPTIONTRACEBACK IS " :@PYEXCEPTIONTRACEBACK
      END

      VEHOUT = RESULT
      RETURN

PYTHON CODE

import requests
import json

headers = {
'Key': 'xxxxxxxxxx',
}

def getdata(func, headers):
    url = 'https://urlgoeshere/' + func
    x = requests.get(url, params=headers)
    return x

def getbaseveh(basevehicleid):
    func = 'basevehicle'
    headers2 = {
        'BaseVehicleID' : basevehicleid,
    }
    headers.update(headers2)
    y = getaamdata(func, headers)
    basevehicle = y.json()
    return basevehicle

JR Moore,

I suspect either an error on the .pth file on the ,pth file in the wrong location (I've been caught out by mixed case myself on Windows for example - Windows file explorer lies). 

You can also explicitly enumerate the module search path using

import sys
import pprint

pprint.pprint(sys.path)


Worth reviewing again:

For the u2py extension module to be loadable in Python, the u2.pth file is placed in specific directories under the bundled Python installation directory.

The following platforms and their associated paths are available for UniVerse:

Platform Path
AIX $UVHOME/python/lib/python#.#/site-packages
Linux $UVHOME/python/lib/python#.#/site-packages
Windows $UVHOMEpython

The full path of $UVBIN is listed in the u2.pth file so that Python will load it into its search path when starting up. The XDEMO's PP directory path is included in the u2.pth file.

Do not add any custom paths to the u2.pth file because this file is overwritten on upgrades.

To add your directories containing Python modules to the module search path, place a unique path configuration file with the .pth extension in the appropriate path for your database and platform.

Each path needed is included on a separate line in the custom .pth files.

For example, on UniVerse and Windows in the $UVHOMEpython directory with a file called myprograms.pth, the paths will look like: 

c:U2AccountsSALESPP
c:U2AccountsRENTALSPP

The custom .pth files are not modified on upgrades.

Remember: Directory paths and the .pth extensions are case-sensitive on Linux and AIX platforms.

Regards

JJ
