Hardware：R7-5800H+32G+3060laptop（6G）  
When I want use AI Lung lobe segmenter in 3dslicer 5.2.2, it asked to install _ **light-the-torch** _.

How could I solve the problem? Appreciate your help！

Did you try the PyTorch extension? Install the extension, switch to the pytorch module and then choose the automatic method. Then re-try the Lung CT Segmenter

Yes, please use the PyTorch extension to install the torch dependencies.

It is an SSL error. Most likely you are connecting to the internet via a proxy server/VPN/firewall that messes with your connection. Can you connect to the internet directly?

@muratmaga @muratmaga @lassoan , \*Thank you so much, I really appreciate your help!  
I reinstall _ **PyTorch extension** _, and try again. It really works. But download speed is very slow(\<30kb/s) cause the _Great FireWall_. Beacause the slow speed, net had dissconnected many times.  
So I meet the dilemma that download speed really slow without a proxy or can not fetch URL via proxy.

Whether you use through pip\_install or via extension, they are going to bring the same package one way or the other. Perhaps what you can do is to obtain the correct wheel name from the pytorch logs, download in a different manner where you can reconnect and continue (curl? wget?), and once you get a copy of the wheel use the pip\_install, but ask to use the local file.

Thank you for your valuable advice. Actually, I want to figure out a way can download the packages manual, and install locally. But I really don’t how to do in 3dslicer.

You can download and pip install packages in Slicer’s Python environment the same way as in any other Python environment. The Python interpreter exectuable is `PythonSlicer`, so you can for example install a package like this: `PythonSlicer -m pip install packagename`

The AI model is stored on github, so you need to resolve your internet connectivity to github. For example, you may try to use a VPN.
