`ImportError` (I think due to numpy dependency)

[TomWagg]

Describe the bug An ImportError occurs when importing exoplanet (will paste below)

To Reproduce

import exoplanet as xo

Expected behavior It imports.

Your setup (please complete the following information):

• Version of exoplanet: 0.5.2
• Operating system: Ubuntu
• Python version & installation method (pip, conda, etc.): 3.10, conda

Additional context Here's my conda env

name: radius-valley
channels:
  - defaults
  - conda-forge
dependencies:
  - python >= 3.6
  - pip
  - numpy
  - astropy
  - pandas
  - scipy
  - seaborn
  - matplotlib
  - jupyter
  - jupyterlab
  - ipython

I think this is because my numpy version is too recent for exoplanet? (see here)

Yeah, PyMC3 requires numpy<1.22:

https://github.com/exoplanet-dev/exoplanet/blob/049d30abcb8a06c37071b7010a62465647ff740a/setup.py#L31

Unfortunately since PyMC3 is deprecated there's nothing we can do about it except downgrading numpy!

[TomWagg]

Okay gotcha, I guess something funky happened with my environment installation that ignored that < 1.22 🤷🏻 Thanks!
