Split_einsum model version missing for sdxl on hub

[rrva]

If I select SDXL as the default model and try to run the app on my MBP, I get:

Starting download of https://huggingface.co/apple/coreml-stable-diffusion-xl-base/resolve/main/coreml-stable-diffusion-xl-base_split_einsum_compiled.zip HTTP response status code: 404

Seems the split_einsum version is missing on the hub

@rrva Yes, the split_einsum version is not ready yet. I have to make a fix to the app to never default to using it when it's not available (up until now, it assumes that the two versions always exist).

@pcuenca Note: this would be an easier "fix" in the new ModelInfo version where each variant is a discrete Model.
