How to solve the question: module 'jaxlib.xla_extension' has no attribute 'CpuDevice', which occurs in Balloon Learning Environment

Downgrade jaxlib to a Compatible Version

Run this to install a known working combo:

pip install jax==0.4.13 jaxlib==0.4.13

These versions still include xla_extension.CpuDevice and are often compatible with BLE.
