Fix runtime warnings #94

mfitz · 2021-09-14T23:08:22Z

Closes #93

Fixes a few hundred warnings - still a few hanging around.

I also had to bump pytest-related versions to make the parallel test stuff work on my local machine, and modified the number of processes so that it is automatically matched to the number of available processors reported by the machine.

I had a brief look at the xfail test, but couldn't see a quick fix for it.

As discussed - this feels pretty hacky, but it gets the job done and only broke a single test in the end. I'm still hoping for a more elegant solution, but at least we know this does work.

I think it's fine. I wonder where we should put this method, there is another one here: https://github.com/arup-group/genet/blob/master/genet/utils/dict_support.py#L115 which is also in theme of working with pandas data, and dict_support is not really the best place for it... should we maybe start a new module in utils.. ?

Yes, I also wondered if this was the best place for it. Perhaps a new pandas-utils module in utils is the thing?

Upgrading pandas scared me slightly, but it didn't break any unit tests or notebooks.

I changed it to >= quite recently, I wanted it to play nicely with MC (but don't need to in the end because SCOP went a different direction). I prefer the fixed versions I think

Strangely, I only had to replace NaN with None in expected routes, and not the other GTFS-related dictionaries. Not sure why this is the case, and did not investigate. Can you think of a reason, and does this seem like a problem?

huh, weird! I would have thought that None would happen when you have a mixture of empty and non empty values in a column, but that's not the case here. I don't think it should make a difference though, pandas considers None and NaN empty, so if you do fillna both None and NaN values will be considered

Wasn't sure of the implications of having to make this change to a test network - could this mean existing networks will be broken now? I used this branch of genet for the network simplification step in a Matesto smoke test pipeline, and nothing fell over, but that doesn't feel like comprehensive reassurance. Presumably any network written by an older version of GeNet (or Puma?) will include the CRS attribute in the deprecated style?

I don't think this will break anything actually, lol
GeNet just writes the projection to xml, doesnt use it (user has to specify the projection for the network always), it does use simplified tag though

I think it would be cool to try read the projection from xml, but we've been doing fine with people specifying each time so I don't feel a strong pull towards it

Ah, okay. Yes, reading the projection from XML seems like a nice-to-have at best.

❤️ the new warning numbers
And loving that we no longer have this dictionary 'init' BS all around, thanks @mfitz !
