Description

qgis version: 3.4.3
OS: debian stretch
Log:

Traceback (most recent call last):
File "/usr/share/qgis/python/plugins/processing/algs/grass7/Grass7Algorithm.py", line 413, in processAlgorithm
Grass7Utils.executeGrass(self.commands, feedback, self.outputCommands)
File "/usr/share/qgis/python/plugins/processing/algs/grass7/Grass7Utils.py", line 416, in executeGrass
startupinfo=si if isWindows() else None
TypeError: __init__() got an unexpected keyword argument 'encoding'

Execution failed after 1.13 seconds

then I remove the encoding parameter in /usr/share/qgis/python/plugins/processing/algs/grass7/Grass7Utils.py, at line 416 and line 372, it works fine.
The problem does not exist on windows.

[processing][GRASS] Fix exceptions on Python < 3.6

Fixes #21173

History

#1 Updated by Giovanni Manghi over 1 year ago

  • Regression? changed from Yes to No

Even on an EN environment (Linux) the tool does not work (but not the same error).

#2 Updated by 李 光耀 about 1 year ago

The python version in qgis is 3.5 and there is no encoding argument for the Popen Constructor according python document, see https://docs.python.org/3.5/library/subprocess.html.

Is this the reason why TypeError occurred?

#3 Updated by Giovanni Manghi about 1 year ago

  • Priority changed from Normal to High
  • Regression? changed from No to Yes

I also think that this works ok on 2.18, but I must check.

#4 Updated by Luigi Pirelli about 1 year ago

usually this error is due to a misconfiguration of python interpreter... grass is using (for some reaon py2) in a py3 context. What is your running context?

I think GRASS still rely on py2

yes, it is Python 3.5.3. Python 3.5.3 is the default version of python3 on debian stretch currently.
Below is the details:

#8 Updated by Alexander Bruy about 1 year ago

This is not misconfiguration, this is because encoding argument for Popen() call was added in Python 3.6 while in some operating systems it can be 3.5 or even lower version. AFAIK we don't require specific Python version, just Python 3 or greater.

Not only r.resamp.rst does not work.
Every GRASS algorithm in the toolbox aborts with this error message under qgis 3.4.4 / UbuntuLinux.
The bug severely limits the usability of qgis 3.4.4.

seems that the command is working correctly... in my error case I have to add resamplig resolution because 0 as default value is not correct. This fail r.resamp.rst => do not generate out raster => more errors trying to read outputs.
So the problem is not that the it does not work, but that the error messages are not so clear.
In the execution case by Givanni, the main error is the first one:
ERRO:Input map resolution differs from current region resolution!

tested with master installed with packages on debian does not generate any error... IMHO can be closed

the original reported issue is not replicable for me, in the meantime the tickets drifted to other errors shown when using this module --> it seems to me this tool is quite a picky beast. I have tested input rasters (DEMs in my case) and I found that some are ingested without problems, others always return some kind of error (mostly "input map resolution differs from current region resolution"). It seems to me that this has nothing to do with QGIS, so I also think this should be closed.

moreover I don't see differences among linux and windows.

#24 Updated by Giovanni Manghi about 1 year ago

I think this GRASS module is sensible to nulls/nodata pixels in the input.

#25 Updated by Luigi Pirelli about 1 year ago

No idea, I can't replicate the original issue, and other issues are not related with QGIS. I leave to you @giovanni to close it if necessary.

The original issue is not reproducable anymore, other issues seems that are possibly related to the GRASS tool itself, not QGIS.

Correct. This is an issue with Python 3.5.
