TreePlanter Tutorial - Execution Failed (Outdoor Thermal Comfort: TreePlanter)

[rarygit]

UMEP Processing installed version: 1.3 (installed from zip file to replace v1.2.1) QGIS version: 3.18.0-Zürich Qt version: 5.12.9 GDAL version: 3.2.1 GEOS version: 3.9.1-CAPI-1.14.2 PROJ version: Rel. 7.2.0, November 1st, 2020

OS: Ubuntu 20.04

Using the Tree Planter Tutorial (https://umep-docs.readthedocs.io/projects/tutorial/en/latest/Tutorials/IntroductionToTreePlanter.html) and the Test Data set (zip file; link to Zenodo) http://doi.org/10.5281/zenodo.4616770

Up to Step 5 in the tutorial (SOLWEIG OUT), everything worked OK and output generated.

Execution failed at the Step "run TreePlanter based on the output from the SOLWEIG run in the previous section." Number of restart iterations:2000 No other Advanced Parameters selected

Save necessary raster(s) for the TreePlanter tool - Yes, and raster outputs generated.

Thanks for any help.

[rarygit]

Trying to understand the error by interpreting the Traceback output.

(i) In relation to the error, are the following issues linked? "0 possible locations for trees..." This is the starting point mtran.pyx: 'a' cannot be empty unless no samples are taken

(ii) Does my error begin with this function script: "StartingPositions.py"?

To a novice the Traceback output seems obtuse and hard to follow.

Started new test with QGIS v3.16 and both UMEP Processing v1.1 (Zenodo) and v1.3 (GitHub)

It seems the From time parameter setting in the TreePlanter tutorial doesn't work for either 13:00 or 10:00 (hour). From time parameter setting 11:00 works.

From (hour): 11:00 Thru (hour): 15:00

Successfully tested for 1, 2, and 3 trees

From (hour): 10:00 or 13:00, both failed with same error: ValueError: 'a' cannot be empty unless no samples are taken

In future, how can I determine the appropriate From and Thru (hour) time settings?

Hi rarygit,

Thank you for trying out TreePlanter! Much appreciated!

I have located the error, which seems to be glob.glob (when loading input data), which isn't necessarily sorting files by name (depends on operating system, it does in Windows, but not in Linux).

I have attached a new version. Hope it works! UMEP-processing-main_rarygit.zip

Cheers, Nils

[rarygit]

Hi Nils, thanks for the explanation and upload!

I will test it now.

In the metadata.txt file it says that this is UMEP-Processing, version 1.1

Should the new version be given as 1.3.1 ?
That is, with the previous bug fixes?

[rarygit]

Recreated all the inputs using your new version (SVF, SOLWEIG etc)

No; TreePlanterfailed with same error if time period is 13:00 to 15:00 Succeeds with 11:00 to 15:00

The Date/Time stamps for all the files in your new archive is 2021-03-18 09:37 Only the folders have 2021-05-31 10:14

Did you change any of the files?

[nilswallenberg]

It doesn't seem to load any layers. Initializing and loading layers doesn't return anything as compared to your third entry, where it did return, but order was weird due to glob.glob.

What layers do you have in your SOLWEIG output directory that you use as input in TreePlanter?

UMEP-processing/processor/treeplanter_algorithm.py should be changed.

[rarygit]

SOLWEIG_OUT3.zip

Attached is the input I created this morning using the new version - all in one folder, including the .qgz file

Inside you will find the SOLWEIG layers

[rarygit]

There are three shadow maps (rasters) with false values (1.79769e+308):

Shadow_1983_173_0000N.tif to Shadow_1983_173_0300N.tif

[nilswallenberg]

Those shadow raster's are fine, they are when sun is below the horizon, i.e. no shadows.

Hmm, have to think a bit. I can run with your SOLWEIG output on Ubuntu 20.04 with QGIS 3.18.3 and the code attached above.

What version of numpy do you have?

[rarygit]

Hi Nils, if I experiment with different From (hours), Thru (hours) combinations, some work, others don't.

e.g. From 09:00 Thru 15:00 or 16:00 fails From (hour) 09:00 Thru 17:00 (hour) succeeds

Have you tried removing the plugin and close QGIS, then reopen and install the new one that I attached here? It is still sorting the files in a weird order.

[rarygit]

Ok, i will try this. And report back in an hour.

[rarygit]

Now it worked! From (hour) 13:00 Thru (hour) 15:00 As below.

Can I install UMEP-Processing v1.3 and then overwrite treeplanter_algorithm.py with your new version? Or will you upload v1.3.1 to GitHub?

Hi Nils, thanks for fixing that problem. The code now runs faster than before.

Which line was the problem in "treeplanter_algorithm.py" ?

[nilswallenberg]

Great! It was in line 256-257.

I have to check if there will be an update today, or later.

Thank you again for testing! :)
