How to install python package on STM32MP157c-dk2?

[SChau.2062]

Hello,

I have followed this link: https://wiki.st.com/stm32mpu/wiki/X-LINUX-AI-CV_OpenSTLinux_expansion_package and successfully flashed STM32MP157c-dk2 device with AI OpenCV image.

Now, I am trying to install python package

scipy

on the device. But it throws error that

"unable to execute arm-openstlinux_wetson-linux-gnueabi-gcc: No such file or directory" 

and

 "error: command arm-openstlinux_wetson-linux-gnueabi-gcc failed with exit status 1"

Could you please guide me? How can I install a python package on a device once the device is booted with AI OpenCV package.

Thanking you,

Saurabh

Hi @SChau.2062​ 

There's, so far, no way to install such package at runtime.

Providing "apt-get" service for such is in the plan for year 2020, we will keep you posted.

In the meantime you have to manage to cross-compile and install package with Yocto.

Hi Olivier,

Is there any improvement so far to install package at runtime using "apt-get"?

I am waiting for this feature to install a python package on a device once the device is booted with AI OpenCV package.

Thanks,

​Hi @SChau.2062​ 

Yes, "apt-get" is now supported in V1.2.0 release delivered 1 week ago.
