AttributeError: 'Series' object has no attribute 'applymap'

Hi Again...
I have another problem :/
The release version of source tracker works absolutely fine but when I download the development version and run exactly the same files, it doesn't work. I am running it with and without the flag --per_sink_feature_assignments (which is why I downloaded the development version). Here's the command and traceback. Any insight?

sourcetracker2 gibbs -i OTU_Table_new.txt -m metadata_new.txt -o OUTPUT

Can confirm, thanks @rebelwebster for posting this.

This is related to an API change in pandas. pd.apply no longer coerces lists into a dataframe so a series of lists is returned instead.

This should be the offending line https://github.com/biota/sourcetracker2/blob/master/sourcetracker/_sourcetracker.py#L234

f = partial(subsample_counts, n=30, replace=False)
type(ftable.apply(f, axis=1, reduce=False, raw=False))
pandas.core.series.Series

vs:

type(ftable.apply(f, axis=1, raw=False, result_type='broadcast'))
pandas.core.frame.DataFrame

I can probably issue a pull request for this this weekend

Great, thanks @johnchase
