sphinx-autodoc-typehints: Error building docs with v1.10

My docs now fail to build with 1.10 (work with 1.9 or lower):

Exception occurred:
  File "/home/janis/.conda/envs/py37/lib/python3.7/site-packages/sphinx_autodoc_typehints.py", line 60, in get_annotation_args
    original = getattr(sys.modules[module], class_name)
KeyError: 'numpy'
