I did the following:

1. Created new python3.9 conda env
2. Ran pip-compile release/air_examples/dreambooth/dreambooth/requirements.txt --output-file=requirements.test.txt. This indeed failed with pip._internal.exceptions.DistributionNotFound: No matching distribution found for jaxlib==0.4.13
3. Relaxed the jax, jaxlib and flax requirements in requirements.txt
4. Ran pip-compile release/air_examples/dreambooth/dreambooth/requirements.txt --output-file=requirements.test.txt again. Here is the result: https://gist.github.com/TimothySeah/5a5e345d581d0b7f97162a4e3a494edb
5. Copied the jax, jaxlib, and flax versions back to requirements.txt

But then that resulted in some dependency issues still: https://buildkite.com/ray-project/release/builds/88314#019d7a74-9760-4595-b080-72d0797c2f4b i.e. ImportError: cannot import name 'cached_download' from 'huggingface_hub'

I repeated the process above but unpinned all the deps this time, which produced this file: https://gist.github.com/TimothySeah/58f928b7d1d611b5ff88d383934e2b5f. I then updated requirements.txt to match. But that was even worse: https://buildkite.com/ray-project/release/builds/88650#019d8961-6343-420f-a3cc-dbb33786b18f.

I went back to the first change but only downgraded huggingface_hub to a version that contains cached_download. Now there's a version mismatch between diffusers and jax: https://buildkite.com/ray-project/release/builds/88671#019d899f-1699-4e39-8b10-9b38effda088

Taking a step back, I see that the from versions log mentions jax 0.4.17 onwards, implying that jax 0.4.13 is no longer supported on my python/cuda setup. Therefore I tried changing it to jax 0.4.17, which produced this requirements file: https://gist.github.com/TimothySeah/465b0b09d46531216fbd9162a183738e. Back to the cached_download error: https://buildkite.com/ray-project/release/builds/88884#019d8e89-b998-48b1-8d8d-7761de4ca484.

Now I'm trying an older huggingface_hub that supports cached_download.

Code Review

This pull request updates the jax and jaxlib dependencies to version 0.4.38 in the Dreambooth template. A review comment identifies a potential compatibility issue where the current flax version (0.6.11) is likely incompatible with the updated JAX versions, suggesting an update to flax (e.g., 0.10.x) to ensure environment stability.
