OpenAI API + GPTCache, similar search cache： not work in flask web API project

[Eric-Huang-LiQiang]

Hi Dear Team,

GPTCache is a wonderful project that has exactly the functionality I need. I can run the OpenAI API + GPTCache similar search cache example program. However, when I tried to apply GPTCache's similar search cache to my actual project, I found that it was not working, even though I had copied the example code.
I have built an API program using Flask, and the example program is executed when the program starts up. I expect to have semantic caching implemented every time a client accesses my API.
How can I check if the example code is working properly?

Those code will be executed when Flask web api go live;

from gptcache import cache
from gptcache.adapter import openai
from gptcache.embedding import Onnx
from gptcache.manager import CacheBase, VectorBase, get_data_manager
from gptcache.similarity_evaluation.distance import SearchDistanceEvaluation

print("Cache loading.....")

onnx = Onnx()
data_manager = get_data_manager(CacheBase("sqlite"), VectorBase("faiss", dimension=onnx.dimension))
cache.init(
embedding_func=onnx.to_embeddings,
data_manager=data_manager,
similarity_evaluation=SearchDistanceEvaluation(),
)
cache.set_openai_key()

Can you show the way that you use the GPTCache in your application
