Why I met this bug?

And the result without onnx and with onnx is different.Why?

What is the number of classes on which you are training/testing?
Default Yolov3 is trained on 80 classes. 255 = (80 + 5)*3
It seems you are training for only 1 class. 18 = (1 + 5)*3
So in your case, simply replace 255 by 18 and it should work.

Please tell me where I should change the config file.

I know the problem.But the result is a little strange.I get the result like [330, 640, 330, 665].Why?

[qgh1223]

The weight should be correct.I get the correct result without using onnx by using detect.py

[Rapternmn]

I think you should create the ONNX File Again.
Make sure :

1. args.reso is equal to resolution mentioned config file
2. Change Line 748-750. Update 255 --> 18 (Since you are doing inference on 1 class)

My previous comment was regarding updating the create_onnx.py file.

[qgh1223]

I found there is another problem.
Layer of type yolo not supported, skipping ONNX node generation.
Error in onnx generation.It cause the wrong detection result?How to solve

Sample Config File?

[qgh1223]

I don't change the config file except the num_classes value.
