File Not Found Error

[dikubab]

The is may be a bug in the code. I tried to figure out. But I could not find it. The path to image looks like broken.
FileNotFoundError: img file does not exist: data/nuscenes/./data/nuscenes/samples/CAM_FRONT/n008-2018-08-01-15-16-36-0400__CAM_FRONT__1533151603512404.jpg

Hi @dikubab. Seems like the data/nuscenes is duplicated. Did you place the dataset the same way as is described in https://github.com/OpenDriveLab/UniAD/blob/main/docs/DATA_PREP.md?

[dikubab]

Yes, I did in the same way. There is no duplication.

I'm checking on this and will notice you once it's resolved.

Hi @dikubab , I cannot reproduce the error. It works well when using the same codes and data_info in this repo.

[dikubab]

The problem is fixed by readjusting /projects/configs/stage1_track_map/base_track_map.py line 419 img_root= 'data_root' to img_root= ""

Thanks. I came across the same issue.

I came across the same issue too when I used v1.0-mini dataset. However it works well when use v1.0 instead.
so I try to find the difference between v1.0 pkls which is pre-generated and v1.0-mini pkls generated by 'uniad_create_data.sh'.
Here is the diff:
when in v1.0 pkls, camera path is like that:
samples/CAM_FRONT/n015-2018-08-02-17-16-37+0800__CAM_FRONT__1533201470412460.jpg
when in v1.0-mini pkls generated by 'uniad_create_data.sh', the camera path is like that:
./data/nuscenes/samples/CAM_FRONT/n008-2018-08-01-15-16-36-0400__CAM_FRONT__1533151603512404.jpg

So,I think there maybe bugs in uniad_create_data for v1.0-mini.

Can you publish a tutorial that uses v1.0-mini? Where should the data be downloaded, how to use bash commands, and how to change the data_root to empty in config files?Thank you ery much！@YTEP-ZHI @dikubab @PengLiangwf

when use mini datasets for inference,in the UniAD/projects/mmdet3d_plugin/datasets/pipelines/loading.py file,at 48 line,comment out the code
from img_path = os.path.join(self.img_root,img_path)
to #img_path = os.path.join(self.img_root,img_path)
it solved the path problem
