The feature in question was [added](https://github.com/biopython/biopython/blob/biopython-182/DEPRECATED.rst#bioseqfeature) in Biopython 1.80, so it does not work with earlier versions. This was by a test in one of my repos after the recent release of 0.7.1 (specifically commit https://github.com/chapmanb/bcbb/commit/eec72c3faca1e5e9e4e48dbf46d396a9045baa3b). Error message snippet: ``` + File "/home/runner/micromamba/envs/augur/lib/python3.8/site-packages/BCBio/GFF/GFFParser.py", line 589, in _get_feature + new_feature = SeqFeature.SeqFeature(SeqFeature.SimpleLocation(start=rstart, end=rend, strand=feature_dict['strand']), feature_dict['type'], + AttributeError: module 'Bio.SeqFeature' has no attribute 'SimpleLocation' ``` ## Workaround Install `biopython>=1.80` ## Potential solution Pin `biopython>=1.80` in setup.py so dependency resolvers (e.g. `pip`) will not be able to install an incompatible version.
