Internal import error on Ubuntu when creating an `Interpreter`

[laclouis5]

LiteRT fails on Ubuntu while creating an Interpreter with the following error:

  File ".../inference.py", line 42, in _load_once
    self._interpreter = Interpreter(str(self._model_path))
                        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File ".../ai_edge_litert/interpreter.py", line 490, in __init__
    self._interpreter = _interpreter_wrapper.CreateWrapperFromFile(
                        ^^^^^^^^^^^^^^^^^^^^
NameError: name '_interpreter_wrapper' is not defined

Environment:

• OS: Ubuntu 24
• Instruction set: x86_64
• Python: 3.11
• LiteRT version: v2.0.2

I installed LiteRT with uv: uv add ai-edge-litert.

Hi @laclouis5,
Thank you for your patience as we have been investigating this issue. We have been unable to reproduce the NameError in a standard pip and venv environment. This strongly suggests that the issue is specific to your environment likely related to how the uv package manager is installing the ai-edge-litert package. If possible could you please give it try with standard pip and venv environment make sure that create new virtual environment using command python3 -m venv LiteRT then activate using command source LiteRT/bin/activate

If issue still persists using standard pip and venv environment please help us with your code snippet or example to reproduce the same behavior from our end to investigate this issue further from our end. Thank you for your cooperation and understanding.
