What is your question?

Hello, I am a starter in pymilvus. my pymilvus version is 2.4.4

# packages in environment at /opt/conda/envs/image_search:
#
# Name                    Version                   Build  Channel
pymilvus                  2.4.4                    pypi_0    pypi

my code is very sample

from pymilvus import MilvusClient
import numpy as np
import os
import time

client = MilvusClient("image_search_wulj_test.db")#3
if client.has_collection(collection_name="image_embeddings"):
    client.drop_collection(collection_name="image_embeddings")
client.create_collection(
    collection_name="image_embeddings",
    vector_field_name="vector",
    dimension=512,
    auto_id=True,
    enable_dynamic_field=True,
    metric_type="COSINE",
)
#4

cnt = 0
from tqdm import tqdm
import json
import numpy as np
with open('truck_data_resnet34.jsonl','r') as fi:
    
    for line in fi:
        filepath = '/opt/data/private/shuowang/image_data/image/image/' #整图
        data = json.loads(line)
        filepath += str(data['path']) + ".jpg"
        for item in data['truck']:
            image_embedding = np.array(item['vector'])
            
            client.insert(
                    "image_embeddings",
                    {"vector": image_embedding, "filename": filepath+item['path']},
                )
        cnt += 1
        # time.sleep(10)
        print('cur cnt: ', cnt)

when i want write embedding infos from a json file to milvus db, it occurs errors: the client.insert() function works fun for the first few minutes, , about several minutes later, it breaks as follows:

Hi @wulongjian , do you have the logs before retry 1? Or start a gRPC service in this way, use client = MilvusClient("http://127.0.0.1:9999") to connect server，This way, the error logs will be clearer.

>>> from milvus_lite.server import Server
>>> s = Server('image_search_wulj_test.db', '127.0.0.1:9999')
>>> s.start()
True
>>> s._p.wait()
