<br>
first check, if your GetCapabilities response is ok (<a href="http://server/wps?service=wps&request=getcapabilities" rel="noreferrer" target="_blank">http://server/wps?service=wps<wbr>&request=getcapabilities</a>) - maybe the plugin is corrupted (it's not the stablest piece of software).<br>
<br>
Then please one more time: check the error.log of your web server, there should be written more - you can pass any exception or error message either to the mailing list or share it via <a href="http://pastebin.net" rel="noreferrer" target="_blank">pastebin.net</a> or similar service<br>

In my case I am using QGIS 2.18 (x32) and Python 2.7.13 (x32) on Windows<br>
10, and I have already added the following environment variables:<br>
<br>
PYTHONPATH:<br>
C:\Program Files (x86)\QGIS 2.18\apps\qgis\python<br>
C:\Program Files (x86)\QGIS 2.18\apps\qgis\python\plugins<br>
C:\Program Files (x86)\QGIS 2.18\apps\Python27\Lib\site-pa<wbr>ckages<br>
<br>
PATH:<br>
C:\Program Files (x86)\QGIS 2.18\bin<br>
C:\Program Files (x86)\QGIS 2.18\apps\qgis\bin<br>
C:\Python27<br>
C:\Python27\Scripts<br>
<br>
Here is the code where I want to import the classes:<br>
<br>
#I would like to use these classes:<br>
# from qgis.core import *<br>
# from qgis.gui import *<br>
# from processing.core.Processing import Processing<br>
# import processing<br>
<br>
from pywps.Process import WPSProcess<br>
from types import FloatType<br>
<br>
class Process(WPSProcess):<br>
def __init__(self):<br>
WPSProcess.__init__(self,<br>
identifier = "processar",<br>
title = "Title",<br>
version = "1",<br>
storeSupported = "false",<br>
statusSupported = "false",<br>
abstract = "Abstract")<br>
<br>
self.value1 = self.addLiteralInput(identifie<wbr>r = "value1", title =<br>
"Input 1", type = FloatType)<br>
self.value2 = self.addLiteralInput(identifie<wbr>r = "value2", title =<br>
"Input 2", type = FloatType)<br>
self.result = self.addLiteralOutput(identifi<wbr>er = "result", title =<br>
"Result", type = FloatType)<br>
<br>
def execute(self):<br>
# Here I would like to write the necessary code to execute the<br>
qgis:extractnodes algorithm:<br>
# processing.runalg('qgis:extrac<wbr>tnodes', 'river.shp', 'output.shp')<br>
<br>
v1 = self.value1.getValue()<br>
v2 = self.value2.getValue()<br>
self.result.setValue(v1 + v2)<br>
return<br>
------------------------------<wbr>--------<br>
<br>
But even with those PATH variables configured I could not access the<br>
algorithm via WPS-client plugin.<br>

Hello people,<br>
<br>
I have a python script that uses some classes from qgis and it runs<br>
correctly in my standalone app (IDLE Python). But when I try to publish the<br>
script through PyWPS (3.2.5), the process does not apear in the list of<br>
GetCapabilities. I think the problem is with the following imports:<br>
<br>
from qgis.core import *<br>
from qgis.gui import *<br>
from processing.core.Processing import Processing<br>
<br>
When I comment these lines the algorithm is showed.<br>
<br>

<br>
I guess the problem is with your environment variable, you should add the<br>
QGIS python and plugins paths to PYTHONPATH and probably the QGIS lib path<br>
to LD_LIBRARY.<br>
<br>
Also, any error message could be useful in order to get some help from the<br>
community. :)<br>
<br>
Regards,<br>
