Downloading dgl==0.4.3 with pip on MacOS Monterey

I’m new to using DGL and I’m trying to run the code from this paper: GitHub - EnyanDai/FairGNN: A PyTorch implementation of "Say No to the Discrimination: Learning Fair Graph Neural Networks with Limited Sensitive Attribute Information" (WSDM 2021)

I’m having trouble installing dgl==0.4.3 The error message states

ERROR: Could not find a version that satisfies the requirement dgl==0.4.3 (from versions: 0.6.0, 0.6.0.post1, 0.6.1, 0.9.0, 0.9.1, 1.0.0, 1.0.1, 1.1.0, 1.1.1)
ERROR: No matching distribution found for dgl==0.4.3

Does anyone have an idea on how to go about installing this version of dgl?
My version of pip is 23.2.1, and I’m using python 3.9.7

There are no wheels for Python 3.9: dgl · PyPI (that version is over 3 years old). You will probably need to upgrade to a newer version of the package to get Python 3.9 (or newer) support.
