[QGIS-Developer] free variable 'self' referenced before assignment in enclosing scope
Dear QGIS community,
In the spirit of open-source I am trying to convert a set of scripts that ive
designed in ArcMap to QGIS 3.x. I hope that this will enable a broader
community of individuals to use the workflows ive designed. The original
scripts can be found at
https://github.com/BjornNyberg/NetworkGT/tree/master/Scripts
My problem is that in my first attempt to convert the scripts, QGIS either
crashes or gives the following error.
2019-01-30T16:51:27 WARNINGTraceback (most recent call last):
File
"C:/PROGRA~1/QGIS3~1.4/apps/qgis/./python/plugins\processing\gui\AlgorithmDialog.py",
line 238, in on_complete
self.feedback.pushInfo(self.tr('Execution completed in {0:0.2f}
seconds').format(time.time() - start_time))
NameError: free variable 'self' referenced before assignment in
enclosing scope
I have established that this error occurs at the very end of the script when
calling ' return {self.Branches:dest_id,self.Nodes:dest_id2}'. I do not believe
that I have explicitly defined self anywhere in the processAlgorithm function
itself. The algorithms themselves work as intended and the shapefiles are
created before the program crashes.
I am not a programmer by trait so I'm not entirely sure how to problem solve
this error and any help would be most appreciated. I can also provide a test
dataset if that is helpful.
Cheers,
Bjorn

[QGIS-Developer] Dijkstra not getting the correct results
Hi, I'm trying to work on a routing problem for my Python plugin and I wanted to use the Dijksta algorithm for that. I used QGIS 3.0 Girona first, but upgraded to 3.4 Madeira recently but getting the same result. I tried to work along the Code from the Cookbook and also used the book "Building Mapping Applications with QGIS" from Erik Westra, which is basically the same Code as in the Cookbook. Since those sources are from QGIS 2 I had to make some adaptions (import from qgis.analysis library instead qgis.networkanalysis and some others) My Code seems to be working now, but the results aren't usful as it no matter what I do only gives me a -1 for every vertex in the tree. I posted my problem on stackexchange with the Code that I'm using. https://gis.stackexchange.com/questions/308244/dijkstra-finding-shortest-path-gives-back-a-tree-with-only-1-in-it I'm a little lost. I don't understand why it is not working. Sincerely Chris Here is a part of the Code I'm using director = QgsVectorLayerDirector(layer, -1, '', '', '', 3) strategy = QgsNetworkDistanceStrategy() director.addStrategy(strategy) builder = QgsGraphBuilder(crs) #crs = project.crs() which is in this case WGS84 tiedPoints = director.makeGraph(builder, [startPt, endPt]) graph = builder.graph() startVertex = graph.findVertex(startPt) (tree, cost) = QgsGraphAnalyzer.dijkstra(graph, startVertex,0) ___ QGIS-Developer mailing list QGIS-Developer@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer
Re: [QGIS-Developer] plugin globe with QGIS 3
Hi Alain, We are in process of adding the features to QGIS gradually. Unfortunately, it is not possible to add all of the features all in one go, as 3D was completely done from scratch in QGIS 3. There will be some new features from the crowd-funding in 3.6. But globe is likely to be included in 3.8. Feel free to contact us if you have any questions.

Re: [QGIS-Developer] plugin globe with QGIS 3
Hi Alain, i don't know if this answer to your question but in QGIS 3.4 you have a 3D Map View. Go to View > New 3D Map View. Please check this link: https://www.lutraconsulting.co.uk/blog/2018/03/01/working-with-qgis-3d-part-1/ The coolest part is the option to integrate this 3D view in layout composer.

[QGIS-Developer] plugin globe with QGIS 3
Hi , the globe plugin has not been ported to QGIS 3 ticket #15536 does not seem to have had any continuation to date. according to https://www.lutraconsulting.co.uk/crowdfunding/more-qgis-3d/ a globe functionality should be developed in QGIS 3 (earth as a globe). what is the roadmap today to have this functionality that interests us for the use of fishing fleet management?
