Critical error

[Mark Fraser]

Encountered this error this afternoon, the only extension I had installed previous to this was forecast.

This is on a Raspberry Pi running Raspbian Buster. Weewx getting weather data using weewx-sdr.

I assume you are running Python 3 (from the error).

What version of forecast are you running?  Exactly where did you get it from?

Yes, I'm running Python 3. I installed it be following the instructions
here https://github.com/weewx/weewx/wiki/forecasting.

[John Kline]

Unfortunately, that version of forecast is not compatible with Python 3. I ported forecast to Python 3 and many of us have been using if successfully for quite some time.

Get it with this:

wget -O weewx-forecast.zip https://github.com/chaunceygardiner/weewx-forecast/archive/master.zip

Cheers,
John

Thanks for that, I thought I saw the green tick next to the forecast
link and therefore compatible with Python 3. I must've been looking at
the line above.
