Several Python values, such as `jnp.bfloat16` (`jax.numpy.bfloat16`), will render badly if we just try to call repr() on them. This module creates an extensible API to register better formatting handlers for ML libraries.

Args: value: Python value, typically a leaf node if there are nested data structures. Data structures are not automatically transformed by this function. import_manager: Import manager used to resolve imports. Returns: Either `value` unchanged, or a ReprString containing code, which when evaluated, returns an equivalent object to `value`. (The exact semantics of equivalence--by object identity or regular equality--is not guaranteed, and mostly a function of what extensions the user has enabled.) csg|]}|qSr )r ).0rr.r r fsz&transform_py_value..)r+r,KeyError TypeErrorrr)r)r. importable_imported_namesr r0r transform_py_valueRs   r7)rr dataclassestypingrrrtyping_extensionsProtocolr dataclassrABCMetarr$r+r-r7r r r r s
