I installed PostgreSQL 10 on win10 system. In order to use QGIS with python, I add the PYTHONPATTH into environment variable，as below：
C:\Program Files\QGIS 2.18\bin;C:\Program Files\QGIS 2.18\apps\Python27\lib;C:\Program Files\QGIS 2.18\apps\qgis\bin;C:\Program Files\QGIS 2.18\apps\qgis\python;C:\Program Files\QGIS 2.18\apps\qgis\python\qgis;C:\Program Files\QGIS 2.18\apps\Python27\Lib\site-packages;C:\Program Files\QGIS 2.18\apps\Python27\DLLs; After PYTHONPATH added, PgAdmin can not start with message "The application server could not be contacted" . When I delete the PYTHONPATH, PdAdmin start nomarlly. Any solution for this problem if I don't want to delete PYTHONPATH from environment variable.
