EnGeoMap crashes upon start

Issue #1356 resolved

Agustin Lobo created an issue 2022-05-05

A soon as Application/GFC EnGeoMAP is selected, it crashes:

ImportError: cannot import name 'loadUIFormClass' from 'enmapbox.gui.utils' (/home/alobo/.local/share/QGIS/QGIS3/profiles/default/python/plugins/enmapboxplugin/enmapbox/gui/utils.py)

Hi, do you use Windows or a Unix/Debian based system (Linux/Mac OS)?

EnGeoMAP is currently only supported on Windows.

Best Regards,

@Helge Daempfling I merged your recent PRs, but the issue still persist.

I just tested under Windows 10 and still get the ImportError.

I am using linux.

EnGeoMAP is currently only supported on Windows.

Then a simple message telling so to the user instead of a crash would nicer. Crashes are a major discredit for any package.

Hi Augustin, we are currently working on a complete revision of EnGeoMAP. I will try to incorporate this or see if can make it run on Linux (also my personal preference)…

@Andreas Rabe

I just installed the EnMAP-Box freshly on a windows 11 computer - after downloading all the missing python packages it works. I can’t reproduce this error with the 3_18 branch. Something must have been changed inutils.py( enmapbox.gui.utils ) in the development branch as the error directs to that file. I will look into it and try to find what you changed there.

Ok, so maybe this solves it:

open …enmapbox/gui/utils.py

and try to change the line

from ..qgispluginsupport.qps.utils import loadUi, SpatialExtent, SpatialPoint, findParent, \ file_search, appendItemsToMenu, zipdir

to

from ..externals.qps.utils import *

or to

from ..qgispluginsupport.qps.utils import loadUi, SpatialExtent, SpatialPoint, findParent, \ file_search, appendItemsToMenu, zipdir, loadUIFormClass

and tell me if the error still comes up.

If you want to run the newest version that I recently committed to run on Linux you must changes the following lines in the according files:

in enmap-box/enmapbox/apps/engeomap/algorithms.py:

the line from osgeo import gdalnumeric back to import gdalnumeric

in enmap-box/enmapbox/apps/engeomap/engeomap_aux_funcul.py:

the line from osgeo import gdal back to import gdal

and the line from osgeo import gdalnumeric back to import gdalnumeric

This should allow it to run the newest development branch under Linux.

I will try to write an OS function that imports GDAL according to the OS used. Actually I believe this should then make EnGeoMAP run under Linux or Debian/Mac OS as well.

The Engeomap that I have is whatever included in EnMapBox 3.10.0.20220401T124144.DEVELOP,

which I understand is older than what you have committed.

Unfortunately, although I can see source files in https://bitbucket.org/hu-geomatics/enmap-box/src/develop/enmapbox/apps/engeomap/

I don’t know how to download a zip for it. I guess I must wait to a newer experimental version of EnMap-Box to test what you are suggesting.

@Augustin Lobo

It should work with your version as well - Then you would just need open this file on your computer:

/home/alobo/.local/share/QGIS/QGIS3/profiles/default/python/plugins/enmapboxplugin/enmapbox/gui/utils.py

and change the following lines with a standard text editor:

from ..qgispluginsupport.qps.utils import loadUi, SpatialExtent, SpatialPoint, findParent, \ file_search, appendItemsToMenu, zipdir

to

from ..externals.qps.utils import *

and save the file. Then restart QGIS and try to load the EnMAP-Box and EnGeoMAP again.

Kind Regards,

Helge

Hi Augustin,

sorry then instead of from ..externals.qps.utils import *

try from ..qgispluginsupport.qps.utils import *

Maybe this works. As it seems the way the utils are imported changed

crash solved! but…

Once the GUI is filled with the file names:

Maybe this already does the trick

try:
    from osgeo import gdal
except ImportError:
    import gdal

Ok, hm I don’t know why gdalnumeric isn’t correctly imported on your machine.

Have you tried it the other way round as I suggested?

( from osgeo import gdalnumeric and

from osgeo import gdal)

Edit: found out why:

https://gis.stackexchange.com/questions/393212/import-gdal-vs-import-osgeo-gdal

import gdalnumeric

and import gdal was entirely removed in the gdal version you are using.

Now also Linux uses the import as I changed it in the last commit

from osgeo import gdalnumeric

from osgeo import gdal

if you get the newest commit or change these lines in the files I mentioned before( just the other way round) it should work on your machine.

Kind Regards,

Helge
