You will need to install and run MONAI Label itself on your local computer (see here → Installation) or collaborate with somebody who provides a MONAI Label server and tells you the IP address that you could connect to.
To fetch the active MONAI Label models you would need to press the green button in your above image.
@muratmaga Thank you answering my question. When I input my address(http://localhost:8000) in my web browser, It occurs error that couldn’t connect in web browser.
Go to View → Extension Manager → Active Learning → MONAI Label
Install MONAI Label plugin
Restart 3D Slicer
To update the plugin to latest version, you have to uninstall existing 3D Slicer version and download + install new preview version of 3D Slicer again.
Please understand that it is not enough to just install the MONAI Label extension. You will need a server, either locally - on your computer, or remotely, on the internet.
Option 1 (local) :
You install the complete MONAI Label software package and server on your local computer.
Please refer to the MONAI Label GitHub Page or this document on how to do that. The computer needs to have a medium to high-end Nvidia GPU.
Then you would need to run the server from the command line, only then start 3D Slicer and use the MONAI Label extension by just pressing the green button mentioned above, without putting anything in the address line.
Option 2 (internet):
You have a coworker who provides a MONAI Label server. Then start 3D Slicer, call the MONAI Label extension, enter the IP address that your coworker tells you, and only then press the green button.
First, I finished setting of IP address in my local pc.
Second, I conducted process regarding setting of MONAI Label sever that you linked above.
After setting IP address in my local PC and installing MONAI Label software package, I tested ‘localhost’ in web browser. But it occurs error message that is “localhost refused to connect.” in web browser. It also occurs error in 3D-Slicer as follow.
In case the installation of MONAI Label outlined above succeeded, you should be able to start the MONAI Label server in a PowerShell (Windows 11) and connect from Slicer 5.1 as follows:
