LAStools problem encoding

[mattia agostino]

Hi everyone, I'm trying to proces a las file with a plugin named OpenLidarToolbox.

While processing appears to me this message:

LAStools console output
Traceback (most recent call last):
File "C:\Users/User/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\LAStools\LAStools\lasground.py", line 75, in processAlgorithm
LAStoolsUtils.runLAStools(commands, feedback)
File "C:\Users/User/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\LAStools\LAStoolsUtils.py", line 61, in runLAStools
feedback.pushConsoleInfo(output.decode("utf-8"))
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x8a in position 17: invalid start byte

Execution failed after 0.03 secondi

Then I try to remove this line from this file LAStoolsUtils.py

feedback.pushConsoleInfo(output.decode("utf-8"))

Then i use again the tool and occurs this error

thread 'main' panicked at 'Impossibile trovare il file specificato. (os error 2)', whitebox-tools-app\src\main.rs:72:21
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Process returned error code 101

Any suggestion?

Hi Mattia,

we had this before in

https://groups.google.com/g/lastools/c/OPOqgEDG1Vk/m/R1ijzqS-AwAJ

As I see you removed the line as suggested there.

I think the result is no valid utf-8 and therefore the decoding fail.

If you remove the line I gues the output is suppressed - may you try the line:

 feedback.pushConsoleInfo(output)  

or

 feedback.pushConsoleInfo(output.decode('UTF-8','ignore')  

If this not work: Can you provide me the files you are testing with and I will see if I can reproduce the problem here.

This is the file

https://drive.google.com/file/d/1lwT4aSncfCKeg2PBOC-ob1TAf0fIuXZL/view?usp=drive_web

I think the problem is on my machine,

 

I try both lines: 

feedback.pushConsoleInfo(output)  --> same error

feedback.pushConsoleInfo(output.decode('UTF-8','ignore')  --> "C:/Program" non riconosciuto come comando interno o esterno,

un programma eseguibile o un file batch.

Execution completed in 0.04 secondi

Algoritmo 'lasinfo' terminato

Many thanks

Hi Mattia,

quite often calls to the OS/QGIS/LAStools struggle with spaces in the commandline.

The output  --> "C:/Program" non ... lead me to this assumption.

So you may try to run something within  "C:\Program files\..."

Try to set your path settings to somewhere where you do not have spaces and/or UTF-8 chars in the file and/or path name.

About the path you can run the command

dir /x

to get the "spaceless" dir alternatives like

20.07.2022  14:11    <DIR>          PROGRA~1     Program Files
18.07.2022  17:34    <DIR>          PROGRA~2     Program Files (x86)

So just use e.g. "PROGRA~1" as your directory name.

Best,

I move the LAStools folder in C:/ and i think now works

Many thanks
