We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
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)

     40 from jax import sharding

ImportError: cannot import name 'monitoring' from 'jax' (/usr/local/lib/python3.8/dist-packages/jax/__init__.py)
