Fix XlaRuntimeError
in JAX
✅ Solution
XlaRuntimeError in JAX often arises from mismatches between the expected and actual data shapes or dtypes within XLA computations, especially during operations like FFTs or when specifying memory layouts. To resolve this, carefully inspect the input shapes, dtypes, and sharding specifications to ensure they align with XLA's requirements and constraints of the targeted device. Explicit dtype casting (e.g., using `jnp.asarray(x, dtype=jnp.complex64)`) or adjusting sharding annotations can often rectify these discrepancies.
