> Unfortunately, the liver model and the default server is not compatible with the latest NVidia AIAA client version (see error report [here](https://github.com/NVIDIA/ai-assisted-annotation-client/issues/76)). You can segment from boundary points (that is faster and more robust anyway) or set up your own server as described in the link provided in [setup instructions](https://github.com/NVIDIA/ai-assisted-annotation-client/tree/master/slicer-plugin#setup).
