when i insert vector to milvus,i get zero results, but the code is copied and pasted over.
When i configured the environment, i copy the code and still get zero results? i don't know...how to say..
i am performing the operation to insert the vector into milvus collection..get zero?
The interface for obtaining the number of milvus data in the code example is inaccurate. As long as there is no error during operation, it is inserted.
@junjiejiangjjj The above situation also occurs to me. How should I adjust it? Can you be more specific? What parameters should I change?

The data has been inserted successfully. You can use the following code to view the actual number.
from pymilvus import MilvusClient
client = MilvusClient(
uri="http://localhost:19530"
)
res = client.query(
collection_name="you collection name",
output_fields=["count(*)"]
)
print(res)
Or you can also view information through this project： https://github.com/zilliztech/attu
@junjiejiangjjj Yes, I saw your answer in another question. Only by using collection.flush() can you see the number of insertions in collection.num_entities.
@junjiejiangjjj我也遇到上述情况了，该怎么调整？能具体说一下吗？要改哪些参数？
数据已插入成功，您可以使用以下代码查看实际数量。
from pymilvus import MilvusClient client = MilvusClient( uri="http://localhost:19530" ) res = client.query( collection_name="you collection name", output_fields=["count(*)"] ) print(res)或者您也可以通过这个项目查看信息：https://github.com/zilliztech/attu

Update pymilvus. I can run it with version 2.4.4 of pymilvus.

Still the same

Maybe you are using an older version of milvus. Try this: https://milvus.io/api-reference/pymilvus/v2.4.x/ORM/Collection/flush.md
@junjiejiangjjj What I installed is pymilvus 2.4.4
I mean the milvus version, not pymilvus
@junjiejiangjjj The inserted data can be displayed in a list and can be added, deleted, checked and modified.
