PY3 Issue with forecast.py

[tut...@gmail.com]

Hi,

I have loaded the latest Python3 version of weewx and made all the updates to forecasting, cmon, and exfoliation to get things back to "normal". However, still getting this syslog output

Oct 20 19:30:25 bdp-rpi1 /weewxd: forecast: ReportThread: _get_stats: '>' not supported between instances of 'NoneType' and 'float'
Oct 20 19:30:25 bdp-rpi1 /weewxd: forecast: ReportThread: _get_stats: '>' not supported between instances of 'NoneType' and 'float'

It looks to be coming from forecast.py but unsure if it is causing any real errors as there are no ignoring file or exiting error from weewx. Has anyone else seen this?

Thanks,

Bryan

What version of weewx-forecast are you using?

Hi John,

I'm only using forecast to generate for the exfoliation skin just as a clarification. So I too k the forecast.py from the new master.zip and installed in the /user/share/weewx/user dir in my installation. I got the following syslog errors.

new forecast.py ignores that html.tmpl versus the original 3.4.0 forecast.py which at least generates the forecasts and both have the Typeerror issue on the _get functions for stats. So I will keep looking at it. Let me know if you have any other suggestions.

Best,

Bryan

Please don’t just take forecast.py.  There were other changes.  Do a proper install

As for the exfoliation skin, I did a port for someone a while back.  She reported success using it.  It’s here:

I will try that. I just don't like it because I have some customizations to exfoliation and forecast and the wee_install ain't to bright and just dumps the default file over the top and I have to hand edit the changes back in.

On exfoliation, I have done the upgrade using your suggested link, and had and done all my customizations, and it seems to work so I don't plan to do a reinstall of that.

Thanks again for your help, much appreciated.
