Fix NotImplementedError

✅ Solution

The "NotImplementedError" in JAX usually arises when a function or operation is called for a data type, or a specific configuration (e.g., sparse arrays, custom autodiff rules, pallas kernels in sharded contexts), that hasn't been explicitly implemented in the JAX backend being used. To fix it, either implement the missing functionality for the given type/configuration, or explicitly use JAX primitives and operations defined for the supported data types, rewriting the code avoiding unsupported operations. Consider using `jax.experimental` libraries to work with experimental features or contributing the missing feature to the JAX project.
