Thank you, it seems that by default an old version of pytorch got installed. We have observed this on some computers, but could not figure out why it happens (why not the latest version is installed). Thr good news that the fix is easy: - uninstall pytorch (you can use Pytorch Utils module for this) - restart Slicer - install Pytorch-1.12 - by typing this into the Python console in Slicer: `pip_install("torch>=1.12")` ---

Thanks for the suggestion, now it worked.But after this updating am getting an error message before starting the slicer. What would be the reason for that? ![image](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/6/8/680c3004a1109c2b35d7e8c394ce1d3536428aa9.png) ---

> [@lassoan](#): > > pip\_install(“torch\>=1.12”) Hi Team, am facing the same error again while running Total Segmentor module, even after installing the 1.12 version pyTorch. ![image](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/7/c/7ccf892f1635c8ecf152ce4b8b548d087c6dcce4.png) ---

Maybe try to install Slicer from scratch into a new folder and install totalsegmentator but not install monai. ---
