请问如何获取检测结果文件

[wanglumeng]

READEME里提到使用的是CenterPoint或者Largerkernel3D的检测结果json文件，请问这个检测结果是能直接在什么地方下载的吗？还是需要用CenterPoint在NuScenes跑一遍检测呢？

来信收到，谢谢！

CenterPoint result is available at tianweiy/CenterPoint#249.
LargeKernel result needs to be regenerated using pre-trained weights.

It would be better if you can share the complete error message (error file, etc.)

After you reported this issue, I re-downloaded the raw detection file from https://mitprod-my.sharepoint.com/personal/tianweiy_mit_edu/_layouts/15/onedrive.aspx?id=%2Fpersonal%2Ftianweiy%5Fmit%5Fedu%2FDocuments%2FCenterPoint%2FNUSC%5FMODELS%2Fnusc%5Fresults%5Fflip&ga=1 and re-ran it according to the Readme.md. Unfortunately, no problems were reported during the run. However, you can download the raw detection file I just ran, and the reorder detector from https://drive.google.com/drive/folders/12QNlMGoqS0RnsvYJh-kP5Cg7wR4h5Pzp?usp=sharing. If you have any questions please contact me.
