Starting the runtime from a Jupyter Notebook broken in v0.1.12

[gmonair]

I'm using the following code to start a runtime from a Jupyter Notebook:

from sglang import function, gen, set_default_backend, Runtime, RuntimeEndpoint

model_name = "TheBloke/deepseek-coder-6.7B-instruct-AWQ"

runtime = Runtime(model_path=model_name, mem_fraction_static=0.8)
set_default_backend(runtime)

This used to work in v0.1.11 and previous versions. Since upgrading to v0.1.12 I get this error:

RuntimeError: There is no current event loop in thread 'Thread-4 (_launch_server)'.
/miniconda3/envs/sglang/lib/python3.10/threading.py:1011: RuntimeWarning: coroutine 'Server.serve' was never awaited

Starting the runtime with python -m sglang.launch_server --model-path meta-llama/Llama-2-7b-chat-hf --port 30000 works as usual.
