Problem with the installation of grounding DINO : No module name torch

[Tristan263]

Hello everyone,

I'm reaching out for assistance as I've already tried many solutions without resolving my issue. Last week, I successfully installed Grounded SAM2 on my PC for testing, and everything worked well. However, when I tried to reinstall the model this week on the same PC (which I had reset for other purposes), I'm unable to install Grounding DINO.

I've followed the repository instructions and installed all the necessary components in my virtual environment just like the first time, but I keep getting the error: "no module named torch" (log attached). I've properly installed torch with CUDA and the recommended versions, created new virtual environments, re-cloned the repository, and even reinstalled Python, CUDA, and my C compiler, but nothing changes - I always get the same error!

I'm open to any suggestions, even the smallest ones. I've also attached a list of the libraries I have installed. It's likely that this is my own error, either due to oversight or incorrect handling.

Thank you in advance for your help!

command use for installation : pip install --no-build-isolation -e grounding_dino

PS D:\Grounding_SAMV2\Grounded-SAM-2> pip list
