To resolve the Docker daemon connection issue, ensure that Docker is installed properly on the host machine where the container is running. Make sure the Docker daemon is running and accessible.

For GPU detection problem, consider the following solutions:

• If running Docker in a Docker container, using the prebuilt Tabby binary might be a simpler approach.
• If building Tabby manually, enable CUDA or other GPU driver by adding the --features cuda option during the build process. Refer to the TabbyML GitHub repository for more details on enabling GPU support.
