Cannot import QgsVectorLayer from osgeo.ogr

Question

I am trying to write a simple script to convert an ESRI geodatabase to a geopackage using gdal/ogr. Here's the example I was using:

from osgeo import ogr

fgdb = r"C:\GIS\data\somefilegeodatabase.gdb"
outdb = r"C:\GIS\data\testdata\OK.gpkg" #Has to be created in advance
fileEncoding = "UTF-8"

driver = ogr.GetDriverByName("OpenFileGDB")
data = driver.Open(fgdb, 0)

#List all layers in the file geodatabase
feature_class_list = []
for i in data:
    foo = i.GetName()
    feature_class_list.append(foo)

#Write to geopackage
for fc in feature_class_list:
    gdbLyr = QgsVectorLayer("{0}|layername={1}".format(fgdb, fc), fc, "ogr")
    print('Writing: ', fc)
    options = QgsVectorFileWriter.SaveVectorOptions()
    options.driverName = "GPKG"
    options.layerName = fc
    options.actionOnExistingFile = QgsVectorFileWriter.CreateOrOverwriteLayer
    options.EditionCapability = 0 #CanAddNewLayer 
    QgsVectorFileWriter.writeAsVectorFormat(gdbLyr, outdb, options) 

Everything works until I get to this line: gdbLyr = QgsVectorLayer("{0}|layername={1}".format(fgdb, fc), fc, "ogr") . This throws an error: NameError: name 'QgsVectorLayer' is not defined I've tried importing in QgsVectorLayer directly from osgeo, but that doesn't work. Has this been deprecated or replaced in osgeo or am I importing it incorrectly?

Answer 1

The osgeo module has never had QgsVectorLayer. That belong to qgis.core module.

Answer 2

As noted in another answer QgsVectorLayer is not and has never been part of the GDAL python bindings.

I think you want gdal.VectorTranslate().

At it's simplest, your code turns into:

from osgeo import gdal

fgdb = r"C:\GIS\data\somefilegeodatabase.gdb"
outdb = r"C:\GIS\data\testdata\OK.gpkg" #Does not need to be created in advance

gdal.VectorTranslate(outdb, fgdb)
