Missing import in schedule.py

[mhasself]

On version '3.0.0a9', schedule.py imports dateutil but not dateutil.parser.

import toast.schedule
schedule = toast.schedule.GroundSchedule()
schedule.read('jupiter.txt')

fails with AttributeError: module 'dateutil' has no attribute 'parser'

But this works great:

import dateutil.parser
import toast.schedule
schedule = toast.schedule.GroundSchedule()
schedule.read('jupiter.txt')

Hi @mhasself , just confirming that this is using the wheel of 3.0.0a9? I don't see a problem locally with toast installed with conda compilers:

$ python
Python 3.10.8 | packaged by conda-forge | (main, Nov 22 2022, 08:26:04) [GCC 10.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import toast.schedule
>>> 

And I see that import in schedule.py. I will test if there is problem with the wheel.

[mhasself]

Yes it's the wheel. The error occurs on schedule.read(), not on the import.

In schedule.py, you need import dateutil.parser, not just import dateutil. I don't see that in a7140ee3, the current HEAD of toast3 branch.

Got it- yes it looks like somehow that import got removed between master and toast3 branches. I'm not sure why we haven't seen that problem until now, but I'll fix it.

[tskisner]

Hopefully fixed in trivial PR #624.

[tskisner]

I'll leave this open until the next tag and wheel confirms the fix.

Thanks!
