天工开物开发包 OpenExplorer 版本：openexplorer/ai_toolchain_ubuntu_22_j6_gpu:v3.8.1，容器docker内开发
fcos3d模型的训练
nuscenes数据集训练fcos3d模型
开发包目录里面的两个文件，/horizon_j6_open_explorer_v3.8.1-py310_20260326/samples/ai_toolchain/horizon_model_train_sample/scripts/configs/detection/fcos3d
img_scale是错误的，正确的应该是img_scale=(512, 896)，height在前，width在后，也就是(H, W)，而不是wh
查看/usr/local/lib/python3.10/dist-packages/hat/data/transforms/detection.py，里面的类Resize()，函数_resize_img也是h在前w在后
