How to export the SwinT model from BEVFusion?

Open slayerlpj opened this issue 6 months ago • 2 comments

I have trained camera+lidar based on SwinT, I have got a pth. How can I generate PTQ model or FP16 model?

I used the command "python qat/ptq.py --config=configs/nuscenes/det/transfusion/secfpn/camera+lidar/swint_v0p075/configs.yaml --ckpt=model/swint/epoch_30.pth --calibrate_batch 300", the I got a error as follow:

How can I fix the problem?
