Script crashes if there are 0 inpatient records w/out discharge date

Hi,

Thanks for the script!

When I run a claims file that is only outpatient data (all inpatient = FALSE), or an inpatient without a discharge date the script produces this error:

Traceback (most recent call last):
  File "run_cv19index.py", line 6, in <module>
    cv19index.predict.main()
  File "c:\Users\chris-pickering\Documents\Projects\cv19index\cv19index\cv19index\predict.py", line 445, in main

    raise AttributeError("Can only use .dt accessor with datetimelike "
AttributeError: Can only use .dt accessor with datetimelike values

To resolve, I changed on claim to be inpatient=TRUE and added a discharge date of today.

Can we update the script for this scenario?

Thanks!
Christopher

Yes, I see that would be the case. Thanks for pointing this out! We will get a fix in.

This is fixed in master. Thanks again for finding it. Will go out in the next release.
