Pandas FutureWarning: Series.__getitem__ deprecation warning

[manzt]

In higlass-python, I'm getting an error with bigwig tracks:

import higlass as hg

ts = hg.bigwig("/Users/manzt/Downloads/data.bw")
hg.view(ts.track().opts(barFillColor="red"))

clodius/tiles/utils.py:275: FutureWarning: Series.__getitem__ treating keys as positions is deprecated.
In a future version, integer keys will always be treated as labels (consistent with DataFrame behavior).
To access a value by position, use `ser.iloc[pos]`
  yield cid, start, chromsizes[cid]

warning is referencing this line:

Is the fix just to chromsizes.iloc[cid]? I'm not familiar enough with the code.

That should be it. I think chromsizes is always a Series[str, int], being indexed by position. The docstring seems to be wrong.
