Issue with exfoliation weewx 4.1.1 and python3 - I think?

[Mike Thompson]

Hi Fourm & Matt,

I'm getting an issue with exfoliation to do with data types the message in the log is  "Reason: '>' not supported between instances of 'NoneType' and 'int'"

I've just migrated from 3.9.1 on RPI Ib running Wheezy.

Upgraded to 3.9.1 on RPI 1B running Buster with Python 2. All was working OK

Upgraded to 4.1.1 on Python3 and the issue occurred.

As apart of the upgrade to 4.1.1 on Python3 I had to make changes to alarm.py etc to update python2 code to python3

Installed latest exfoliation (0.45)  and forecast (3.4.0b1) extensions. It looks like exfoliation has over written my customisations so I think it's "out of the box"

Seasons is working - pages and graphs generate OK.

Forecast seems to be working. Sample pages generated OK, most without data but UK met office data on forecast-periods page. Time stamp on files in public_html/forecast are recent i.e post upgrade.

Some Exfoliation pages are generated OK and some not, index and forecast are not but history, almanac and links are.

From syslog it looks like get_windspeed_trend is causing the issue

It may have something to do with changes and extensions I've made over the years. To be fair, I've just bumped along working this out from first principles until it worked so it's highly likely I've not implemented changes correctly

From my weewx.conf the only section regarding exfoliation is;

    [[exfoliation]]
        HTML_ROOT = public_html/exfoliation
        skin = exfoliation
        #radar_local_img = http://radar.weather.gov/ridge/lite/N0R/BOX_loop.gif
        #radar_regional_img = http://radar.weather.gov/ridge/Conus/Loop/northeast_loop.gif
        #radar_national_img = http://images.intellicast.com/WxImages/Radar/usa.gif

        # MT Addition for forecast and alltime,sevenday
        [[[CheetahGenerator]]]
            search_list_extensions = user.forecast.ForecastVariables, user.stats.MyStats

I've run with exfoliation commented out in weewx.conf as well as enabled=false and weewx is running without error

Syslog attached.

before 09:35 I was running 3.9.1 on Python 2

after 09:35 4.1.1 on python 3

post 12:36:37 debug is turned on

Thanks in Advance

[Mike Thompson]

I've had some time to investigate it's the forecast extension that's upsetting things.

Had anyone else had this issue?

I’m having the exact same issue

For the first error, in file index.html.tmpl, line 226, change this

#if $varExists('trend') and $trend.windSpeed.raw is not None

      $get_windspeed_trend($trend.windSpeed.formatted)

#end if

to this

#if $varExists('trend') and $trend.windSpeed.raw is not None

      $get_windspeed_trend($trend.windSpeed.raw)

#end if

For the second error, there are a number of candidates that could be causing this problem. I'd go with this one. Change this

#if $show_pop

        <td class='col-pop'>

  #if $period.pop.raw > 0

          $period.pop.format('%.0f',' ')

  #end if

<br/>

  #if $period.qpf.raw > 0

          $period.qpf.nolabel('%.2f',' ') <img class='pop-img' src='icons/raindrop.png' />

  #end if

<br/>

  #if $period.qsf.raw > 0

          $period.qsf.nolabel('%.2f',' ') <img class='pop-img' src='icons/snowflake.png' />

  #end if

        </td>

#end if

to this

#if $show_pop

        <td class='col-pop'>

  #if $period.pop.raw is not None and $period.pop.raw > 0

          $period.pop.format('%.0f',' ')

  #end if

<br/>

  #if $period.qpf.raw is not None and $period.qpf.raw > 0

          $period.qpf.nolabel('%.2f',' ') <img class='pop-img' src='icons/raindrop.png' />

  #end if

<br/>

  #if $period.qsf.raw is not None and $period.qsf.raw > 0

          $period.qsf.nolabel('%.2f',' ') <img class='pop-img' src='icons/snowflake.png' />

  #end if

        </td>

#end if

But I could be wrong on that.

I changed the first one and all my errors went away.  I’m not sure I was having the second part of the error.

I have a similar problem with python3 and extension. The index and history pages are being generated. I made the first change listed above, but my index template doesn't have a show_pop. Here is the syslog extract:

I did a quick port of exfoliation for someone who wanted to get it to work with WeeWX 4/Py3.

You are welcome to try it:

If you want it to work with the forecast plugin, I have that working with WeeWX4/Py3 at:

Thanks, that port does work, and forecast already worked. My skin is modified from exfoliation, so what I'd like to know is what lines had to be changed in the templates to make it work with python3?

You can see exactly what I changed here:

Thanks! Those changes fixed all. You can see my pi weather server at  http://millennialhouse.ddns.net/wx/
