Fix JaxRuntimeError
in JAX
✅ Solution
JaxRuntimeError often indicates an internal error within JAX's XLA compiler or underlying CUDA/cuDNN/cuSOLVER libraries. Try updating JAX, CUDA, and cuDNN to the latest compatible versions. If the error persists, consider disabling XLA autotuning via `jax.config.update("jax_disable_jit", True)` as a temporary workaround and report the issue with a minimal reproducible example to the JAX issue tracker.
