[Qgis-user] Python error on startup

Tue Nov 22 13:22:54 PST 2016

Hi,

Next time, I recommend you install Anaconda Python.  It come with a number of scientific packages.  You can indicate during the installation that you do not want to change the environment variables.

> 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.
