[Qgis-user] Python error on startup

[Stephen Ban]

Hi,

 

I recently started getting an error message when launching QGIS. I can't
pinpoint exactly when it started happening, but I'm pretty sure it must be
related to a recent install of Python when I had both Python 2.7 and 3.5
installed. I also have ArcGIS on my machine, so that was the only Python
version installed for awhile. I then installed Python 3.5 to do some
testing, but have since uninstalled it so the only remaining standalone
Python version is ArcGIS's 2.7. I've purged any extraneous Python
environment variables and cleaned the Windows registry to no effect. I'm
running Windows 10 64-bit edition, and have always installed the 64-bit
versions of QGIS.

 

I was originally running GQIS 2.16.1, then uninstalled it and installed QGIS
2.18. Both versions give me the same error message on startup: "Python
error: Couldn't load plugin 'processing' See message log (Python Error) for
more details." The Python message log contains the following:
"1 Traceback (most recent call last):

Any help or advice on resolving this error would be appreciated.
