tensorRT output and Pytorch->ONNX output are not same by FP32 inference

hi,
I am now trying to use tensorrt to speed up the detection algorithm. Using FP32, I find that the output is inconsistent between tensorrt and pytorch, and the model’s featmaps are inconsistent.
We transfer pytorch model to onnx model.And

  1. inputs are consistent.
  2. Comparing the model parameters of onnx and pytorch, we find that the model parameters of onnx and pytorch are consistent
    I don’t know what went wrong.
    I hope the authorities can help me out.
    thx

the Platform of tensorrt is Win10,the Platform of pytorch is ubuntu,I use the RTX5000 GPU,
the model is ResNext-101
