outputs not stop
Download CodeLlama-7b-hf model and test the results of the given example as follows:
sequences = pipeline(
'import socket\n\ndef ping_exponential_backoff(host: str):',
do_sample=True,
top_k=10,
temperature=0.1,
top_p=0.95,
num_return_sequences=1,
eos_token_id=tokenizer.eos_token_id,
max_length=2000,
)
But the outputs of the model can not stop.

3.4.2. 异步的重试机制
在上一节中,我们使用了一个简单的算法来实现重试。这种方式是非常有效的,但是如果你想要更多的控制,那么你可以使用异步的重试机制。
