I have a similar question to this thread:

Trying to use "Difference" tool gives out "'QgsWKBTypes' is not defined" error

According to image [1], I've received this message when I trying to run TauDEM's Pit Remove algorithm in QGIS 2.18.5:

global name 'escapeAndJoin' is not defined. See log for more details.

I've located the file TauDEMUtils.py [2] but I'm not a programmer so I don't know what to do. Until now, there's no solution to this question.

My System: Ubuntu 16.04.2 LTS

This is a bug in the file TauDEMUtils.py. Just edit your file (you'll need administrative privileges - e.g sudo) as shown in this link:

  • There is a problem with the code in the above link. When I tried it, the TauDEM command was changed to: m p i e x e c - n 2 p i t r e m o v e - z D : / j u n k / 4 G P r o j e c t s / T u t o r i a l P r o j e c t 1 / L i d a r / q 4 7 1 2 2 b 3 2 b e . t i f - f e l C : \ U s e r s \ L E N N Y ~ 1 .

I can't believe that I am the only one experi

  • Hi Robotuner. This issue was fixed in QGIS 2.18.6 point release, but now we have a 2.18.7 in official site. See this info here: issues.qgis.org/issues/16366
