[Qgis-developer] qgis 3 still includes qt4+py2 stuff and missing _gdal_array.pyd

[Idan Miara]

Hi,

I wondered why does the latest qgis 3.0 weekly build (2.99.0-18) still
contains some qt4 and py2.7 binaries.
OSGeo4W.bat still defaults to qt4+py2.7 (separate batch files
qt5_env.bat, py3_env.bat are required to run in order to work with qt5+py3).

also, _gdal_array.pyd is missing from
apps\Python36\Lib\site-packages\osgeo
and available only on:
apps\Python27\Lib\site-packages\osgeo
(same for x64 and x86 releases)

[With the latest gisinternals binaries, I could find _gdal_array.pyd in the
file:
release-1800-gdal-mapserver.zip\bin\gdal\python\osgeo\_gdal_array.pyd
but not in the x64 version.]


thus the following code fails:

import gdal
x = gdal.Open(r'D:/Map Samples/1/DTM/n29w098d5dtm.tif')  #valid tif
y = x.ReadAsArray()
print(y)


produces this error:
