TosaSerializer

✓ from tosa_serializer import TosaSerializer

✗ from tosa import TosaSerializer

Demonstrates serialization and deserialization of TOSA models using the tosa package.

import os from tosa import TosaSerializer, TosaDeserializer # Serialize a simple TOSA graph serializer = TosaSerializer() # Build graph... (omitted for brevity) # binary = serializer.serialize() # Deserialize from file filename = 'model.tosa' if os.path.exists(filename): deserializer = TosaDeserializer(filename) graph = deserializer.deserialize() print('Graph loaded successfully') else: print('Model file not found')

Debug

Known issues

breakingVersion 2026.5.0 dropped support for Python 3.9; minimum is now Python 3.10.

fix

Upgrade Python to 3.10 or later; pin to tosa-tools<2026.5.0 if stuck on 3.9.

affects: >=2026.5.0

breakingThe TosaSerializer API changed: 'addTensor' renamed to 'add_tensor' and 'addOperator' to 'add_operator' (snake_case alignment).

fix

Update code to use snake_case method names: add_tensor, add_operator.

affects: >=2025.12.0

gotchaImporting from 'tosa_tools' instead of 'tosa' silently fails. Many users try 'import tosa_tools' which succeeds but has no meaningful symbols.

fix

Use 'from tosa import ...' or 'import tosa'.

affects: all

gotchaThe MLIR translator requires the optional 'mlir' package and a compatible MLIR version (>=14). Missing it raises ImportError at runtime.

fix

Install with 'pip install tosa-tools[mlir]' or ensure mlir is on PATH.
