TypeError: 'DataContainer' object is not subscriptable（The error occurs in the evaluation stage）

[yudefu]

Hello: When I loaded the pre-trained first-stage model for evaluation, the following error occurred; I searched on Google, it is probably caused by the mmcv version, but I see that the mmcv version mentioned in our installation documentation does not have my version High; Please help me to see!

my locale
mmcv-full 1.5.3+corex.3.1.0
mmdet 2.24.0
mmdet3d 1.0.0rc3 /home/work/yudefu/mmdetection3d
mmengine 0.8.0
mmsegmentation 0.20.0
py3.9.7
torch 1.13.1+corex.3.1.0

@yudefu Hi, both of your installed mmcv and mmdet3d have higher version than what's required in this project. You may need to create a new environment and install the requisite version of packages.

Okay, thank you very much; we don’t seem to have a low version of mmcv and mmdet3d adapted here, if you can’t solve it by installing a low version, do you have any good way to solve that error?

Add

img_metas = img_metas[0].data
img = [img[0].data[0].cuda()]

before this line

Add

img_metas = img_metas[0].data
img = [img[0].data[0].cuda()]

before this line

If I try add '''img_metas = img_metas.data[0]''', it won't get solved. But your sentence is a nice one.
Thanks. It works on my devices. (Pytorch1.13.0-cuda118, mmdet=2.14.0, mmdet3d=0.17.1 on H800)
