Dear colleagues,
I am not aware of Shear Wave Splitting measurement software using Obspy (but something may exist) but note that we have put online a new version of SplitLab (that works in Matlab) under Github, that includes corrections / evolutions mostly from J.-R. Scholz (IPGP - La Réunion) and M. Bonnin (Univ. Nantes). I am not sure it could be easily used for automatically measure thousands of splitting from local events but it could be definitively adapted for such purpose as proposed by Andreas Wuestefeld few years ago?

By the way, note that we also maintain a SKS splitting database which is completely opened to the community.
There are now more than 16 000 SKS splitting measurements and more than 250 reference papers in this database.
You can download and search data in the SKS database at
http://splitting.gm.univ-montp2.fr/ under the “Splitting database” link
or at the IRIS web site (updated daily)

Do not hesitate to mention missing or erroneous data.
best wishes,
