IndexError: list index out of range

[brauhausdc]

Got the following error when trying to install - system is a fairly updated Raspi-OS install, and has python3.9 on it. Any pointers would be appreciated. Did get it to install on a different machine, running ubuntu 22.04, but haven't been able to get it to actually give me any output using "modeslive --source net --connect [my-flight-aware-server-IPaddress] 30005 beast"

Was trying to install locally on the pi-aware server but get a Out of range error:

    a[b] = a[b] + ',' + a[b + 1]
IndexError: list index out of range

Full error:

Could you upgrade your pip version and retry? If it still doesn't work, please copy paste your pip version here.

Upgrading from the Debian/Rasp-Pi OS distributed: pip 20.3.4 from /usr/lib/python3/dist-packages/pip (python 3.9)

To : pip-23.0

appears to have fixed the issue — though also necessitated/facilitated upgrading numpy and a few other bits before pyModeS installed.

I used: python -m pip install --upgrade pip

To do the pip upgrade

And then just did: pip install pyModeS

To install things. Compiling took a while on the Pi, but seems to have worked.

As a side note, the “modeslive” command still doesn’t work for me — it doesn’t show any output save the frame and text at the top of the screen, but a home built simplistic client script using the module does — its based on the "Customize the streaming module” section of the docs. Would be lovely for modeslive to have a “-D” or “-v” for debug or verbose, or similar. Have tried both "modeslive --source net --connect localhost 30002 raw” and "modeslive --source net --connect localhost 30005 beast” neither produces any spots.

Thanks again for the help.
