I installed the following packages I am using python 3.8 and cuda 11.7. Installing using a requirements file

mmcv == 1.4.0
mmcv-full == 1.4.0
mmdet == 2.20.0

Then when I run

from mmdet.core import DistEvalHook

I get the trace

When I print the torch configurations I have

torch == 1.13.1+cu117
Younger330 commented 11 months ago

I have the same question with smiliar version, have you solve this problem?

hejianzhong commented 3 months ago

I also met the problem like yours when I runned python demo/image_demo.py demo/demo.jpg rtmdet_tiny_8xb32-300e_coco.py --weights rtmdet_tiny_8xb32-300e_coco_20220902_112414-78e30dcc.pth --device cpu.
