Import error on Python 3.9 #164
Description
Hi Dan,
I understand celerite is superseded by celerite2, but it would still be nice to keep the functionality alive for allesfitter users on Python 3.9.
To replicate the error: I set up a brand new conda environment with Python 3.9 and full anaconda. Then I pip-installed celerite and tried to import it as shown below:
(env_python39) Maximilians-iMac-Pro:~ mx$ pip install celerite
Collecting celerite
