Hi everyone,
I'm currently working on a project using the Luckfox Pico Ultra W with Buildroot. I'm trying to convert an ONNX model to RKNN using the RKNN-Toolkit2, but I've encountered issues during the conversion process.

Model information:
The model I'm using is the Yolov5 fire detection model, which can be found at: https://github.com/spacewalk01/yolov5-f ... main/model

I tried converting the ONNX model to RKNN using RKNN-Toolkit2 versions 1.6.0 and 2.3.0
I referred to the RKNN Inference Test guide on the Luckfox wiki and followed the steps there.
Previously, I was able to implement an object detection example using YOLOv5 from Rockchip following the RKNN Inference Test guide, and this model worked well.

Errors Encountered:

With RKNN-Toolkit2 version 1.6.0:

ValueError: Unsupport file 0!

Even though I upgraded the toolkit, the error persists, and the model fails during the build phase.

Questions:
1. Has anyone encountered a similar issue with Luckfox Pico Ultra W or RKNN-Toolkit2 when converting ONNX models?
2. Are there any specific steps or configuration changes I can apply to resolve the "Unsupport file 0!" error?
3.Could the issue be related to the model itself (e.g., unsupported operators or opset issues), and how can it be resolved?

I would appreciate any advice or tips on how to move forward with this issue.

Thank you!

Hello, the NPU of RV1106 itself supports limited operators, the yolov5 routine mentioned in the wiki is based on the https://github.com/airockchip/yolov5 repository, the difference compared with the mainline repository is that the SiLU activation layer is replaced with the ReLU activation layer, and the post-processing part is handed over to the CPU for processing;
The model you plan to convert is obtained from other repositories, and there may be several operators in the model that are not supported and cause the conversion to fail, or there may be a reference dataset (parameter .. /dataset/50.txt) is not set correctly
