How to install additional Python dependencies on the DK2

[JDUMA]

Hello, I'd like to install Python dependencies to run a RTL-SDR python program on the discovery kit and I failed to execute the following command line below : 

apt-get install python-numpy  (or python3-numpy).

Do you know how to install numpy on the DK2 ?

Hi @JDUMA​ 

apt-get service is not yet available for OpenSTLinux, it will come with next V1.2.0 release in February this year.

In the meantime, actually python3-numpy is already part of the Distribution package but not compiled and installed by default.

2 ways to install it on target, the complete/proper one :

Adding it to RDEPENDS_packagegroup-framework-tools-python3 variable in layers/meta-st/meta-st-openstlinux/recipes-st/packagegroups/packagegroup-framework-tools.bb and rebuild the full image and reflash it on the DK2.

one shortcut for a try :

do "bitbake python3-numpy"

The generated debian package will be available in : tmp-glibc/deploy/deb/cortexa7t2hf-neon-vfpv4/

Copy it on target and install it with dpkg -i python3-numpy*.deb

Hope it help
