Getting error while installation.

Hi, I was trying to install celerite2 from source code following the instructions in the documentation. But while testing the code I got an error:

python -m pytest -v python/test                                                                                                                                                      ─╯

Thanks! This was an incompatibility introduced in the most recent PyMC/PyTensor release. Once https://github.com/exoplanet-dev/celerite2/pull/94 is merged, it should work again.
