Issue setting up Geotrace on Mac qgis 3.20

[jaspermowatt]

Hi,

Having an issue trying to use geotrace on mac running qgis 3.20. I know it's not the stable version but the same issue was experienced in the stable versions of 3.+.

Below is the error message. Any help greatly appreciated

An error has occurred while executing Python code:

UnboundLocalError: local variable 'out' referenced before assignment

Hi,

It looks like you have an issue installing scikit-image. Can you open the python console (open the plugins menu) in QGIS and run the code

import skimage

if this isn't successful can you try:

import subprocess subprocess.run('pip install scikit-image')

This should install scikit-image or give you an error message.

Good luck

Hi thanks for the reply,
First go didn't work, here is the error:

import skimage
Traceback (most recent call last):
File "/Applications/QGIS.app/Contents/MacOS/../Resources/python/code.py", line 90, in runcode
exec(code, self.locals)
File "", line 1, in
File "/Applications/QGIS.app/Contents/MacOS/../Resources/python/qgis/utils.py", line 799, in _import
mod = _builtin_import(name, globals, locals, fromlist, level)
ModuleNotFoundError: No module named 'skimage'

Second didn't either:

import subprocess subprocess.run('pip install scikit-image')
Traceback (most recent call last):
File "/Applications/QGIS.app/Contents/MacOS/../Resources/python/code.py", line 63, in runsource
code = self.compile(source, filename, symbol)

return _maybe_compile(self.compiler, source, filename, symbol)

codeob = compile(source, filename, symbol, self.flags, 1)
File "", line 1
import subprocess subprocess.run('pip install scikit-image')
^
SyntaxError: invalid syntax

Tired splitting the command and this didn't work either:

import subprocess
subprocess.run('pip install scikit-image')
Traceback (most recent call last):
File "/Applications/QGIS.app/Contents/MacOS/../Resources/python/code.py", line 90, in runcode
exec(code, self.locals)
File "", line 1, in
File "/Applications/QGIS.app/Contents/MacOS/../Resources/python/subprocess.py", line 489, in run
with Popen(*popenargs, **kwargs) as process:
File "/Applications/QGIS.app/Contents/MacOS/../Resources/python/subprocess.py", line 854, in init
self._execute_child(args, executable, preexec_fn, close_fds,
File "/Applications/QGIS.app/Contents/MacOS/../Resources/python/subprocess.py", line 1702, in _execute_child
raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'pip install scikit-image'

Any further advice would be greatly appreciated.

Cheers

Hi,

I believe the issue you are having is related to macosx. I have a colleague who had some issues getting GeoTrace installed, I'll try and find out how they solved the issues.

Cheers,
Lachlan
