Unable to install the new tflite-support using pip

问题

Following this link, I've been trying to install the tflite-support module using pip. I get the following error:

ERROR: Command errored out with exit status 1:

Any leads? I know similar questions have been asked before, but no luck with those answers

Turning the comment into an answer:

This looks like a regression in setuptools. Downgrade to 41:

$ pip install --upgrade 'setuptools<42'

Now (ideally) preinstall pybind11 to avoid missing headers when building the tflite-support wheel:

$ pip install 'pybind11>=2.4'

Now installing tflite-support should succeed without any intermediate errors:

$ pip install tflite-support
