question about export the model into torchscript

[Zalways]

i exported the model into torchscript format, and when i use the exported model to inference on image,it only can inference on the image that i used for exporting model, but for other image,it cann't work,and the error message is: /root/miniconda3/envs/deepsolo/lib/python3.8/site-packages/torch/nn/modules/module.py:1051: UserWarning: Named tensors and all their associated APIs are an experimental feature and subject to change. Please do not use them for anything important until they are released as stable.
