Thanks, this additional information helps a lot. It is likely that your institution interferes with your internet access.

You can find several similar topics, see for example [[1]](https://discourse.slicer.org/t/error-when-installing-matplotib-in-slicer/28141) and [[2]](https://discourse.slicer.org/t/about-using-totalsegmentator/34539/3).

Probably the simplest solution is to install Slicer and extensions on a computer with proper internet access and then copy that Slicer to the computers where you need to use it. Slicer is fully portable, so if you only copy the Slicer installation folder and downloaded TotalSegmentator weights from your user folder then it should all work.

You can choose a GPU (cuda) computation backend and click install.

However, since you seem to have an internet connectivity issue, you need to do this on a different computer or ask help from local IT personnel to get usable internet connection.

My network can get online, are you talking about my 3D slicer network connection problem? How to fix it?

It is not a 3D Slicer network connection problem, but an issue with your computer network settings (e.g., invalid/temporary SSL certificates issued by Zscaler or similar network security software on your computer) or your internet connection (e.g., aggressive proxy server preventing internet access of applications).

Ouch! How to solve this problem? Please give me some Pointers! So how do you do that?
