They converted the original JAX weights to the format that Pytorch uses. Because JAX is still fairly new, it can be a lot easier to get Pytorch to run on e.g. CPU. I do find the number of upvotes interesting and I imagine many people just upvote things that have DALLE in the title, to a degree.
Look how much easier it is to install & run, people are interested in and up-voting the result, not how much work was (or wasn't) required to achieve it.

Unfortunately, following the instructions to build JAXlib from source (https://jax.readthedocs.io/en/latest/developer.html#building...) result in several 404 not found errors, which later cause the build to stop when it tries to do something with the non-existent files.
Unfortunately, it looks like I won't be running this today.
Not to discourage the OP of course, great work.
