osgeo64/processing: bag magic number in yaml

[qgib]

Original Redmine Issue: 16188
Affected QGIS version: master
Redmine category:windows_package
Assignee: Jürgen Fischer

Just installed current dev version (bb2a6c8) on Windows here (next to 2.14) which fails to start processing because of
ImportError: bad magic number in 'yaml': b'\x03\xf3

'
see screendump

FYI: this is 64bit Windows Server 2008 R2 Enterprise install

Reassigning to Jürgen- this seems an error in the yaml package itself, not in processing.

• category_id was changed from Processing/Core to Windows Package
• assigned_to_id was changed from Victor Olaya to Jürgen Fischer

Not reproducable here. Apparently it's a stale pyc. Is python3-pyyaml installed? qgis-dev depends on it.

Ok - confirmed. Removing all .pyc files from the osgeo4w folder and restarting fixed this for me.

Thanks for looking into it. I cannot confirm untill next week when I'm working on that machine again.

So this is a left over from a qgis.2x run in the same folder?
Could be because I installed from an excisting osgeo4w install/folder.

What I'm curious now for is if this could also happen when you install both 2.x and 3/2.99 in same osgeo4w64 folder and first run 2.x (generating .pyc files) and then try to run 3 (picking up those files?)...

Feel free to close it, I will open it when it does not fix my problem.

The python3 and python2 installs are different directories. Interesting would be which file it actually is.

That should work.

I had the same problem... Deleting C:\OSGeo4W64\apps\qgis-dev\python\yaml\init.pyc seemed to help...

Is it safe to remove it?

Yes - that's from an previous python2 based qgis-dev. Fixed in 702d4cc.

Yep, confirmed here too. Removed all *.pyc files and works!
