Fix JaxRuntimeError
in JAX
✅ Solution
JaxRuntimeError usually arises from inconsistencies between the JAX code and the underlying XLA compiler or runtime environment, such as unsupported data types or operations on specific hardware. Inspect the error message for details about the offending operation or data type, and either revise the JAX code to use supported constructs or update the JAX and XLA versions to ensure compatibility with the target hardware/software environment.
