[yocto] Reducing the size of the image by optimizing python

[Abhi Arora]

Thanks for the reply. Can you help me which file to modify to prevent downloading certain packages and modules using BAD_RECOMMENDATION?

And how to have only pyc files in the final image to improve speed and reduce footprint?

Following are the lines in my yocto project which install python packages.

IMAGE_INSTALL_append = " \
    python3 \
    python3-core \
    python3-misc \
    python3-async \
    python3-six \
    python3-websockets \
    python3-requests \
    python3-urllib3 \
    python3-chardet \
    python3-websocket-client \
    python3-pyopenssl \
    python3-simplejson \
    python3-cython \

Pardon for some stupid questions as I am new to yocto.

Hello,
I am having an embedded system. We have bsp with python 3.5 but we want to reduce its size further. I am planning to have only oyc files but not sure how it can be achieved in recipes. Also, I want to know if there is a other way to reduce the footprint.

Please start by eliminating modules first so find which modules are required for your workloads and remove all other modules from image by adding them to BAD_RECOMMENDATIONS from IMAGE_INSTALL


Please help.
