Parse failed on yolov8n_obb

im using an oriented object detetion yolo model, when i run runner.translate_onnx_model i afraid as it mention hailo translation not support trig operation. if i chose after the yolo head later it might lose some of the valuable postprocess operation any suggestion

Hey @SAN

The problem you’re facing stems from the Hailo ONNX model translation process, which doesn’t support certain operations - specifically trigonometric functions like Cos and Sin, as well as a broadcasting shape issue. Hailo’s dataflow compiler and runtime software (HailoRT) may not directly support these operations, so you’ll need to find alternative solutions.

Here are some approaches to address this:

  1. Preprocess Trigonometric Operations: Move Cos and Sin calculations outside the model. Perform these operations during data preprocessing instead.
  2. Create a Custom Post-Processing Step: Implement unsupported operations (like trigonometric functions and shape manipulations) as a post-processing step on the host CPU. This allows you to run the main inference on Hailo hardware while handling unsupported operations separately.
  3. Adjust Model Architecture: Replace unsupported operations with approximations or alternatives that the Hailo Dataflow Compiler can handle.
  4. Use Recommended End Nodes: Try parsing the model again using the suggested end node: “/model.22/df1/Reshape_1”. This may help avoid some unsupported nodes.
