Install openslide-python==1.1.1 error

[PeijinV5]

Hi,

How are you? I am a PhD student in Bioinformatics and Computation Medicine department at University of Michigan. I am trying to install the "requirements.txt". There was an error when trying to install open slide-python==1.1.1:

File "/tmp/pip-install-686n_fkx/openslide-python_83c86f6362ad4cd58c21cf001e9b9bb2/setup.py", line 2, in
from setuptools import setup, Extension, Feature
ImportError: cannot import name 'Feature' from 'setuptools'

I highly appreciate if you could let me know how can I fix it!

Thank you very much,
Peijin
