SOLVED: TV metadata lookup not working

[Medieval Cow]

Hi all, the TV metadata lookup on my system used to work but stopped successfully returning results a while ago (Movie metadata lookups still work fine). I finally took some time to dig into it a little today, and I can't figure out what's going wrong. Here's the log output I see when I look up a TV episode:

Code: Select all

This is for an episode of Reno 911. I added in the 72336 TV ID manually. Without it, I get a hit for the movie Reno 911: Miami. With the ID code entered, I get "Decoding Nazi Secrets", which is what that ID returns on the TMDB site. So it seems to fail to get a hit as a TV show and return whatever it finds for a movie lookup.

Running the "/opt/local/share/mythtv/metadata/Television/ttvdb.py -l en -a US -D 72336 6 13" command directly in Terminal gives me this output:

Code: Select all

ImportError: No module named ordered_dict

So it looks like the ttvdb.py script is choking on something when it runs, so it moves on to the tmbd script and returns movie data instead. I can't figure out why that's started happening though. Anyone have any ideas?

I'd say the pertinent error is the 'ImportError: No module named ordered_dict'.

What version of MythTV are you using?

You need to downgrade pythons urllib3 package.
See viewtopic.php?f=36&t=3274
for details.

I'm running MythTV 0.28.2-Fixes-20180201_6 on Mac OS X 10.12.6.

I installed via MacPorts, so I was able to use that to roll back to an older version of py27-urllib3 (specifically version 1.22_0, which was an older version I was running on this machine) but I'm still hitting the same error. So it seems like there's something else going on giving the same error as that thread, unfortunately.

Python allows tow ways to install packages:
- Install locally on user session
- Install a package globally for all users

The local install for a dedicated user takes precedence to the global install.
In your case, the urllib3 package seems to be installed locally. See the file paths in the log.

Please try in a terminal the following with the user running mythfrontend:

Code: Select all

python2
>>> import urllib3
>>> urllib3.__version__
>>> urllib3.__file__

This gives you the version and file path to the urllib3 package python is using.

To change the locally installed package for urllib3, please try

Code: Select all

pip install --user urllib3==1.23

and run the above checks for version and file location again.

Hey, that worked! Ya'll are amazing, thanks so much!

Ugh, this system is great when it works, but I have some regrets about how I set it up, and at this point it feels like everything is held together with bubblegum and duct tape. One of these days I'm gonna decide I want to ruin my weekend and go ahead and backup my database so I can move everything over to a fresh Linux install.
