[gdal-dev] Fwd: Missing _gdal_array.py, fail to import in Ubuntu 18.04

[Even Rouault]

(please keep the list cc'ed in your replies)

There's no such file as _gdal_array.py. But there should be a file named like 
_gdal_array.cpython-36m-x86_64-linux-gnu.so with the native code of the 
binding corresponding to gdal_array.py
Perhaps try make clean before rebuilding
