pip install pyperseus-treebankPyPerseus treebank is a really simplistic tool to deal with original Perseus and Perseids treebank XML format (such as https://github.com/perseids-project/harrington_trees ).

from pyperseus_treebank.latin import LatinCorpus
corpus = LatinCorpus("./tests/test_data/tb.latin.xml")
