Failed to search vectors in Milvus:Index out of range And Failed to load data to Milvus: 'NoneType' object has no attribute 'insert'

Hello everyone, I have two errors when I use Image Similarity Search with object detection. What are the reasons for this? There is no response in web search, the following is my environment.

The Error:

2021-09-09 23:04:04,120 | ERROR | milvus_helpers.py | search_vectors | 107 | Failed to search vectors in Milvus:Index out of range
ERROR 0m: Exception in ASGI application

It means that your search is incorrect, you can check the search vectors.

2021-09-10 07:48:36,401 ｜ ERROR ｜ milvus_helpers.py ｜ insert ｜ 66 ｜ Failed to load data to Milvus: 'NoneType' object has no attribute 'insert'

I think it occurs when Milvus does not connect successfully, so the Milvvus object is None, and it does not have 'insert'. So please check the Milvus connections and you can refer to this issue #636

[akimisr]

I have the same problem with you. Maybe you can solve this problem with add a code line in milvus_helpers.py.
self.set_collection(collection_name)

[shiyu22]

@akimisr I think you are right, the code self.set_collection(collection_name) is missed, you can refer to milvus_helper in video_search, and can you submit a pull request to reverse_image_search to become a contributor :)

[avats-dev]

@shiyu22 opened PR with the required changes, please review! Looking forward to contribute more. 🎉

Thanks @avats-dev :) Closed by #808
