History

#1 Updated by Tony Walters 9 months ago

Went back to a laptop with 3.4 Madeira and IDW interpolation works correctly. Also ran 3.6 on the laptop and failed there as well.

Status bar jumps immediately to 99% finished, but hangs there. Normally it shows the processing progression from 1% onwards.

Cheers,
T

I tried on both Windows and Linxu on 3.6 and can't replicate (but maybe depends on what column is used to interpolate? what do you used?).

Also where is the data to test the raster clip?

Hi Giovanni,

I almost feel embarrassed like I'm reporting errors that are unique to my install.

Here is a typical log report:

----------------------------------
Processing algorithm…
Algorithm 'IDW interpolation' starting…
Input parameters: { 'DISTANCE_COEFFICIENT' : 10, 'EXTENT' : '377194.8269227125,423458.1550825302,4893116.891602981,4926995.061894643 [EPSG:2961]', 'INTERPOLATION_DATA' : 'F:\\GIS\\South Shore\\SouthShoreModel\\Analysis\\IPT_Feb_28\\IPT_MODC_unique.shp::~::0::~::2::~::0::|:', 'OUTPUT' : 'C:/Users/tonwa/AppData/Local/Temp/processing_011cc56ee4374c2a9fa07ac9ac6993c7/8a3fb811d84e41e39011912aca925068/OUTPUT.tif', 'PIXEL_SIZE' : 0.1 }

Execution failed after 21.03 seconds

Loading resulting layers
Algorithm 'IDW interpolation' finished
-------------------------

I have tried using layer extent and also canvas extent with no success. The reason it fails in this case in 21.03 seconds is I click repeatedly on Cancel and it eventually finishes. If I didn't cancel it, it runs all night/forever. Example of attribute file is attached. Interpolation attribute is 'Download_S".

When I selected "use layer extent" this morning, the following Python error:

2019-03-27T10:17:53 WARNING Traceback (most recent call last):

AttributeError: type object 'QgsMapLayerProxyModel' has no attribute 'MeshLayer'

This all used to work fine originally.

I did a clean install of 3.4 LTR as well and this is where the above data is coming from.

I also ran Grass r.surf.idw on the same shapefile. It did complete successfully with log as follows:

Even this algorithm seems to have a problem with selecting "use layer extent", but is ok with "select minimum extent from all layers"

The issue with clip raster with vector layer may have been mis-reported. I started another of this task early this week and it did complete successfully, although took 2 full days of compute on a very fast Intel processor.

it is quite normal that there could be local issues. This does not means is the case, but the fact I can't replicate (also on the same OS) is usually a strong evidence,

I did a clean install of 3.4 LTR as well and this is where the above data is coming from.

the pyhton error was already fixed, you will not see anymore in the next point release for 3.4

Anyway... in the original description you state that you were seeing the problems in 3.6 and not 3.4.5... now you say another thing. You see the issues in both?

shapefile link https://we.tl/t-paTmZGMOAl

do you see the issues with the shape, the gpkg or both?
What is the field to be used to interpolate?

it depends on the datasets you used, can you link them?
