Hey there! Thanks for sharing the details of your YOLOv8n pose estimation model deployment. Based on your log, it seems there are several warnings during the ONNX conversion process which might impact the performance when using TensorRT. These warnings indicate operations that failed to execute could be causing inefficiencies in the model when run using TensorRT. Also, consider that TensorRT and PyTorch may have differences in handling certain operations or optimizations. Here are a couple of suggestions:
Since model optimization can be quite specific to the operations used and hardware architecture, sometimes it may require a bit of fine-tuning to get the best performance out of TensorRT. I hope this helps! If you need more detailed guidance, feel free to ask! 🚀 |
Thanks for your respond, the warning doest happend when i try to convert onnx sperately and use trtexec to convert to TensorRT. i cant inference. Is there any solution to this.
|
I have set simplicity = False, and convert successfully without any warning. The result is still slower than Pytorch. Can you suggest any solution? |
@namogg hello! If converting without warnings still results in slower TensorRT performance compared to PyTorch, you might want to consider the following adjustments:
Each model and hardware combination might require unique tweaks to fully optimize, so these steps could help pinpoint more effective configurations. Keep experimenting! 🚀 |
I havent solve the problem yet but thanks for your support |
You're welcome! Keep experimenting with the settings, and if there's anything more we can help with, don't hesitate to reach out. Best of luck with your project! 😊 |

Question
I inference YOLOv8n pose estimation model. The pytorch model predict batchsize 4 is around 20ms and tensorrt is 25ms.
This is my convert setting
model.export(format = 'engine', dynamic = False, batch = 4, half = True, imgsz = 640)
TensorRT version 8.6
Pytorch 2.2.1
Cuda 11.8
Ultralytics 8.1.47
