FileNotFoundError when using SOLWEIG

[jonas260492]

First, thank you for your great tool! I am calculating maximum comfortable walking distances for pedestrians and SOLWEIG delivers me the Tmrt needed. I seperated my case city in ca. 9000 microclimatezones and wrote a script to automate the SOLWEIG tool with my inputs with UMEP Processing.

When I now run my script I get the following error, which I cannot explain:

Traceback (most recent call last): File "C:\OSGEO4~1\apps\Python37\lib\code.py", line 90, in runcode exec(code, self.locals) File "", line 1, in File "", line 76, in File "C:/OSGEO4~1/apps/qgis/./python/plugins\processing\tools\general.py", line 108, in run return Processing.runAlgorithm(algOrName, parameters, onFinish, feedback, context) File "C:/OSGEO4~1/apps/qgis/./python/plugins\processing\core\Processing.py", line 174, in runAlgorithm ret, results = execute(alg, parameters, context, feedback, catch_exceptions=False) File "C:/OSGEO4~1/apps/qgis/./python/plugins\processing\gui\AlgorithmExecutor.py", line 71, in execute results, ok = alg.run(parameters, context, feedback, {}, False) _core.QgsProcessingException: Traceback (most recent call last): File "C:/Users/jonas/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\UMEP-processing-main\processor\solweig_algorithm.py", line 831, in processAlgorithm data = np.load(folderPathPerez) File "C:\OSGEO4~1\apps\Python37\lib\site-packages\numpy\lib\npyio.py", line 417, in load fid = stack.enter_context(open(os_fspath(file), "rb")) FileNotFoundError: [Errno 2] No such file or directory: ''

When using UMEP GUI it works perfectly. Thanks for your help in advance.

Best Jonas

Please provide info on OS and versions of tools and software. The latest version of umep processing should be 1.3.

Windows 10 Pro. I installed QGIS as described in the UMEP manual.

I just updated to version 1.3 and now it raises this error:

Traceback (most recent call last): File "C:\OSGEO4~1\apps\Python37\lib\code.py", line 90, in runcode exec(code, self.locals) File "", line 1, in File "", line 76, in File "C:/OSGEO4~1/apps/qgis/./python/plugins\processing\tools\general.py", line 108, in run return Processing.runAlgorithm(algOrName, parameters, onFinish, feedback, context) File "C:/OSGEO4~1/apps/qgis/./python/plugins\processing\core\Processing.py", line 174, in runAlgorithm ret, results = execute(alg, parameters, context, feedback, catch_exceptions=False) File "C:/OSGEO4~1/apps/qgis/./python/plugins\processing\gui\AlgorithmExecutor.py", line 71, in execute results, ok = alg.run(parameters, context, feedback, {}, False) _core.QgsProcessingException: Traceback (most recent call last): File "C:/Users/jonas/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\UMEP-processing-main\processor\solweig_algorithm.py", line 534, in processAlgorithm if (dsmraise != demraise) and (dsmraise - demraise > 0.5): UnboundLocalError: local variable 'demraise' referenced before assignment

Actually I just had a look at the solweig_algorithm and saw that in line 292 it is written dem=0, so actually the processing should not use dem to derive buildings but landcover? But why do I get the problem then?

Moreover I saw: folderPathPerez = self.parameterAsString(parameters, self.INPUT_ANISO, context) so if it is like this, do I need to use shadow maps as an input also? I didnt want to do it.

Thanks a lot. Jonas

Thanks. Can you please attach the log output so That I can see your full settings when running the model.

Where can I find this? There is no file created like for the succesful completition for SOLWEIG GUI.

This is part of my script: processing.run("umep:Outdoor Thermal Comfort: SOLWEIG",{'INPUT_DSM': inpath_DOM, 'INPUT_SVF': inpath_SVF, 'INPUT_HEIGHT': inpath_WHeight, 'INPUT_ASPECT': inpath_WAspect, 'INPUT_CDSM': inpath_nDOMv, 'TRANS_VEG': 3, 'INPUT_THEIGHT': 25,# check value 'INPUT_LC': inpath_LaCov, 'USE_LC_BUILD': True,

'INPUT_DEM': inpath_DEM,

Aha, sorry, you run as standalone script. I suggest you just run the model in the toolbox to get the correct input parameters. Then just copy and paste for the log message window.

Thank you so much. This was a good hint. Now everything is working smoothly!
