ImportError: DLL load failed while importing _ext: The specified module could not be found.

Background

I'm using a win-10 computer to install mmcv. After trying installing with the common "pip" command, the "pre-build package" problem occured. Then I followed the instrctions on here to install mmcv from source.

Info

My computer has cuda version of 12.6 and torch version of 2.3.0+cu118. I thought i followed the instructions accurately and successfully in the previous website. However, when checking the mmcv according to the command "python .dev_scripts/check_installation.py", it raised the error:

I tried restart the computer but nothing changed.

P.s

It's my first time to raise a question like this, so if there is any information that i forgot to provide just let me know. Thanks a lot!
(Btw, i'm a sophomore with little experience dealing with problem like this /whimper)
