ImportError: DLL load failed: The specified procedure could not be found

Hi,

I am not well skilled for programing and have recently started mmdetection...
I met an ImportError as trying the verification script. The error is as below:

Traceback (most recent call last):
File "", line 1, in
File "C:\Users\shinrin\mmdetection\mmdet\apis_init_.py", line 2, in

return _bootstrap._gcd_import(name[level:], package, level)
ImportError: DLL load failed: The specified procedure could not be found.

My versions:

Name Version

cudatoolkit 11.1.1
mmcv-full 1.4.8
mmdet 2.23.0
python 3.7.13
pytorch 1.9.0
torch 1.9.0+cu111
torchvision 0.10.0+cu111

What causes this error?
I appreciate if you could help to solve it.
