I download the cbct, click apply, and the download begins, which lasts indefinitely. nvidia rtx 4070 gpu. then I entered this command (slicer.util.pip\_install(“acvl\_utils==0.2”) into phyton and now I have a new problem, the program does not see the cuda drivers. help me pls

Hi Imran.

The Troubleshooting for Total Segmentator works also for Dental Segmentator, you can find it on the Lasso’s GitHub page, heres the link:

[https://github.com/lassoan/SlicerTotalSegmentator?tab=readme-ov-file#troubleshooting](https://github.com/lassoan/SlicerTotalSegmentator?tab=readme-ov-file#troubleshooting)  
Probably you should:

- Install Nvidia Drivers
- Download CUDA for that Drivers
- Install Pytorch for that CUDA Version
- Use Pytorch Utils Module to get everything working on 3dSlicer (a few Restarts required)

Hope it helps.
