Lorenzo,
you didn't mention which Linux distro you used and how you installed numpy
I'm aware at least that on Alpine Linux, you need to install an
additional py3-numpy-dev package with the headers & lib needed to use
the C API of numpy, which is needed by the GDAL Python bindings
Check that the following returns something sensible
python3 -c "import numpy; print(numpy.get_include())"
when you build the GDAL python bindings look for the following messages
in the output that will indicate that the gdal_array module can't be built
"WARNING: numpy headers were not found! Array support will not be enabled"
or
'WARNING: numpy not available! Array support will not be enabled'
Even

Hi everyone, basically i build from source GDAL 3.2.2 and install the
python bindings via pip3 install gdal==3.2.2
Later i install numpy, i have read online that the numpy must be
installed before GDAL python bindings.
So i tried to uninstall python gdal and than reinstall it, but the
problem still persists.
Do you have any suggestions about it?
Python3 libraries:
GDAL 3.2.2
NUMPY 1.21.2
SWIG 4.0.2
