python AttributeError: 'NoneType' object has no attribute 'get_event_loop', lmql == 0.7.3

[TioeAre]

I'm trying a simple test in https://towardsdatascience.com/lmql-sql-for-language-models-d7486d88c541, and code like this

import lmql

query_string = """
"Q: What is the sentiment of the following review: ```The food was very good.```?n"
"A: [SENTIMENT]" where (SENTIMENT in ['positive', 'negative', 'neutral'])
"""
print(lmql.run_sync(
    query_string,
    model=lmql.model("local:llama.cpp:/home/lmql/llama.cpp/models/zephyr-7b-beta.Q4_K_M.gguf",
                     tokenizer='/home/zephyr-7b-beta', cuda=True)).variables['SENTIMENT'])

however there comes error,

Exception ignored in: <function lmtp_model.__del__ at 0x7fd63813c680>
Traceback (most recent call last):

I got the same error message when I tried running the following query via lmql run:

argmax 
    "Say 'this is a test':[RESPONSE] \n"
from
    lmql.model("local:meta-llama/Meta-Llama-3-8B-Instruct", cuda=True)
where
    len(RESPONSE) < 50

And the error message:

Say 'this is a test': The art of the emergency broadcast system
The sE
