Classification models don't need the prototxt. Object detection models need the prototxt. Also some other models such as for keypoint detection and 3DOD also uses a similar mechanism as object detection - they also use prototxt.
Thanks for your response!! Thanks!
But I found that some tflite format object detection models also do not have prototxt, like delow:
Are prototxt files also related to the ONNX and tflite formats? And if my customer model is an object detection model, how can I generate the prototxt for the model? Is there some script for the generation?
Thanks!!!
If you check the object detection onnx models, there are several small operators at the end that effects the performance.
Actually the prototoxt is not needed, onnxruntime-tidl is able to offload only the supported layers to underlying TIDL and run it on DSP and run the remaining unsupported layers (at the end) on the ARM. But that will be slow. The prototxt is a mechanism to offload all those layers into a Detection Post Processing operator in TIDL.
If you check the .tflite models, most of them have already compacted those operators into a Detection Post Process layer. TIDL is able to understand this layer layer in tflite - hence prototxt is not needed.
But certain tflite models do not come with this compact operator - in that case the performance will be affected - and this case the prototxt will help to improve the performance.
Thank you very much for your detailed answer!!!
Hi mathmanu. I still want to ask, if my customer model is an object detection model, how can I generate the prototxt for the model? Is there some script for the generation?
Thanks!
Thanks a lot! You are very nice!
@BJ-ZhaoXiaoyang Have you found some way to generate the prototxt? I want to generate it for NanoDet-Plus
Hello, I have a question about prototxt. I found that in the modelzoo, some models do not have prototxt files, as shown below:
while some models have prototxt files, as shown below:
When/where are prototxt files needed and when/where not needed? What is the relationship between the prototxt file and artifact file/ And How do I generate prototxt files for the Customer model?
I am looking forward for your reponse!
Thanks!
