Hello, I'm trying to automate changes in the projection used by the map canvas. If I open the python console and use the following command sequence: novus_CRS = '+proj=lcc +lat_1c.0 +lat_2u.0 +lat_0p.0 +lon_0=-97.0 +datum=WGS84 +no_defs' crs = QgsCoordinateReferenceSystem.fromProj4(novus_CRS) qgsProject = QgsProject.instance() qgsProject.setCrs(crs) This works fine. However, and when I try to incorporate it programmatically (e.g. in a plugin), I keep getting the error: Failed to open /usr/local/share/qgis/resources/data/world_map.gpkg However, this file seems to be in the right subdirectory: $ cd /usr/local/share/qgis/resources/data ubuntu@ip-172-31-23-167:/usr/local/share/qgis/resources/data$ ls -l total 12744 -rw-r--r-- 1 root root 2542 Jun 8 2022 README_world_map.md -rw-r--r-- 1 root root 27743 Jun 8 2022 contributors.json -rw-r--r-- 1 root root 17711 Jun 8 2022 contributors.qml -rw-r--r-- 1 root root 8355 Jun 8 2022 qgis-hackfests.json -rw-r--r-- 1 root root 18507 Jun 8 2022 qgis-hackfests.qml -rw-r--r-- 1 root root 4412 Jun 8 2022 user_groups.qml -rw-r--r-- 1 root root 8897 Jun 8 2022 user_groups_data.json -rw-r--r-- 1 root root 12914688 Jun 8 2022 world_map.gpkg -rw-r--r-- 1 root root 25158 Jun 8 2022 world_map_generalize.model3 Not sure why of this behavior discrepancy console vs. programmatically. Thanks. AF
