TypeError: '<=' not supported between instances of 'int' and 'NoneType'

[Dan'l B]

Running 5.2 in a venn on Ubuntu VM in Parallels, with Forecast extension 4 installed and it throws me the following error. I can go look at line 143 but am not sure how to cure the error.

Please skins/forecast/forecast_table.inc with the file attached and let me know how that works out.

John,

Swapped that in, and we still seem to have the error. Do you need more info from me?

The error is happening because the program is trying compare an empty value with an integer. This was ok in very old python but not in Python 3.x. What you need to do is change the comparison to first check if the variable is none before doing the comparison. If the variable is X, it's something like

if X is not None or X >= 1234:




You can ask Claude or ChatGPT or some other LLM to help with the syntax if you get stuck.

I sent him a file that checks for on every comparison.

Actually, you no longer have that error.  This one is in forecast_strip.inc

These values should probably not be None, but the code shouldn’t error on this.  I’ll send you a forecast_strip.inc shortly.

By the way, this isn’t my code, but I seem to be the maintainer of it now.

Dan’l, it would help to know if you have nulls for sun/moon rise/set, or nulls in the tides.  Do you have xtide installed?  Are you trying the new alamanac?

My guess is that $alm.sunrise.raw and friends are None.

If you are using the new almanac, try removing it and see if you still get errors.  Either way, get back to me.

As for xtide, if you are using it, tell me how you installed it.

You can simply set enable=false for it to switch it off and use the original one instead.
