Initializing Hugging Face Transformer restarts program loop

Initializing hugging face transformer causes loops to restart. I have created simple loop which reads text and replies but the loop is restarting new thread when initalizing chatbot pipeline. Minimum replication example given below.

from transformers import pipeline
from transformers.pipelines import Text2TextGenerationPipeline

chatbot_model = pipeline(task="text-generation",model="facebook/blenderbot-400M-distill")
i=0
while(True):
    try:
        if (i%2)==0:
            print(f"{i} - Even")
            i = i+1
            time.sleep(0.5)
        else:
            i = i+1
            continue
    except Exception as e:
        pass

Output loops restart after chatbot initialization after printing 40 and seems other loop starts from 0. Same is when i read files in a loop. Is is due to to multiple threads. How is it working? Output mentioned below.
