These helpers produce a stable JSON graph representation that preserves object identity and references.

The JSON graph is a textual representation of the object graph that preserves shared references. It can be used for debugging or simple persistence. Parameters ---------- obj The object to save. metadata Extra metadata to save into the json graph string. Returns ------- json_str The JSON graph string. Examples -------- .. code-block:: python import tvm_ffi a = tvm_ffi.convert([1, 2, 3]) s = tvm_ffi.serialization.to_json_graph_str(a) b = tvm_ffi.serialization.from_json_graph_str(s) assert list(b) == [1, 2, 3] )rToJSONGraphString)rrr R/home/ubuntu/veenaModal/venv/lib/python3.10/site-packages/tvm_ffi/serialization.pyto_json_graph_strs rjson_strcCs t|S)aMLoad an object from a JSON graph string. The JSON graph string is produced by :py:func:`to_json_graph_str` and can be converted back into the corresponding FFI-backed objects. Parameters ---------- json_str The JSON graph string to load.
