Hello, I'm working on porting a Python 3 application to the AM572x EVM running PSDK 4.1, and I'm having issues installing a required library. My application was written for Python 3.5.2, which is the same version of Python that is built into PSDK 4.1, however my application uses the asyncio package, which I'm having trouble running on the EVM. I've used Yocto to add Pip to both Python 3.x and 2.7 by adding
IMAGE_INSTALL_append += ' python3-pip' and IMAGE_INSTALL_append += ' python-pip'
Now I can download and install asyncio, and the other package I need (pyserial). But when I try to run my application, I'm notified that the multiprocessing package is not installed. Multiprocessing has been a standard Python library since Python 2.6, and I cannot seem to install it to Python 3 using Pip due to a syntactical error in multiprocessing. It does however install to Python 2.7 using Pip, but doesn't run in 3.5.2.
Is there a way that I can configure Yocto to have all of the default Python 3 packages?
This is the error I'm receiving when I try to run my application:
# python3 application.py

You are using pip version 8.1.2, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
