  Cannot import flax.training.checkpoints in 0.6.4
  ### System information
  - OS Platform and Distribution: Ubuntu 22.04.1 LTS, also in Colab environment
  - Flax, jax, jaxlib versions:
    * flax 0.6.4
    * jax 0.3.25
    * jaxlib 0.3.25
  - Python version: 3.10.6
  - GPU/TPU model and memory: No Accelerator / 16GB
  
  ### Problem you have encountered:
  With FLAX v0.6.4 I can't import `flax.training.checkpoints` module due to following error:
  ```
  ImportError: cannot import name 'monitoring' from 'jax' (/usr/local/lib/python3.8/dist-packages/jax/__init__.py)
  ```
  This does not happen in v0.6.3.
  
  ### What you expected to happen:
  The module should be imported.
  
  ### Logs, error messages, etc:
  Error message from jupyter notebook:
  ```
  ImportError                               Traceback (most recent call last)
  
  [<ipython-input-3-9a234296e658>](https://localhost:8080/#) in <module>

       36 from flax import traverse_util
       37 import jax
  ---> 38 from jax import monitoring
       39 from jax import process_index
       40 from jax import sharding
  
  ImportError: cannot import name 'monitoring' from 'jax' (/usr/local/lib/python3.8/dist-packages/jax/__init__.py)
  ```
  
  ### Steps to reproduce:
