inference score become low #99

Open Chen-cyw opened 2 years ago

Chen-cyw commented 2 years ago

In some classes(not all) ,the scores of infrerence results become low(eg from 0.8 to 0.25) after transform to tensorrt model, test by the same object in the same picture. the mmdetection model config like this:
