[BUG] Cannot install salesforce-merlion conda package in a python 3.9 environment on Mac

[namaya]

Describe the bug

The salesforce-merlion conda package is not installing in a python 3.9 environment. Instead, the following
error is being thrown

Encountered problems while solving:
  - package salesforce-merlion-1.0.0-pyhd8ed1ab_0 requires fbprophet, but none of the providers can be installed

To Reproduce

Create a python 3.9 environment and activate it

mamba create -n py39-env -c conda-forge 'python=3.9'
mamba activate py39-env

Install salesforce-merlion into environment

mamba install -c conda-forge salesforce-merlion

Expected behavior

salesforce-merlion conda package is installed and available in python environment.

Screenshots

Desktop (please complete the following information):

• OS: MacOS 12.0.1
• Merlion Version: 1.1.2

Additional context

These steps use mamba as it provides a clearer error message, but using conda directly doesn't work either. Also trying mamba install -c conda-forge salesforce-merlion>=1.1.2 didn't help either.

I think the main reason for this is that the conda-forge feedstock still has merlion requiring the (old) fbprophet instead of the newer prophet. Probably just need to get those dependencies back in sync with what is in the setup.py here.

Yeah, this sounds correct. @namaya I'm not the one maintaining the conda recipe, so I'd recommend taking this issue up with the maintainers of that repo.
