Perhaps you can help figure this out, maybe i just overlook something. So i have a point cloud which a imported from a lidar-data-file (laz). Now, to generate a raster data set, i planned on using the TIN-Interpolation plug-in (well, i guess it is a tool now, not a plug-in). But any time i open the tool and try to select any parameter, the tool just crashes.

Stacktrace: AttributeError: 'NoneType' object has no attribute 'name' Traceback (most recent call last): File "F:\qgis/apps/qgis/./python/plugins\processing\algs\qgis\ui\InterpolationWidgets.py", line 117, in addLayer self._addLayerData(layer.name(), attribute) AttributeError: 'NoneType' object has no attribute 'name'

Do you have any idea on how to work around this issue, how to do it differently or what i might have done wrong?

  • The error sounds like no valid layer is passed to some Python function. Are you sure you use the dialog correctly? Maybe you have to explicitly select a layer somewhere?

  • @bugmenot123 I observed that the tool crashes not at the very start, but when i try to select the layer (which just happend to always be when i start the dialog). I now suspect the problem to be with my point cloud, i will try to find it.

    I now processed the laz file back and forth and at some point the TIN-Interpolation dialog recognized the layer as valid and it worked just fine. Most likely the problem was with my dataset then. Thanks for the advice.
