[Bug]: Why can't ATTU display sparse vector in the UI?

[lingvisa]

Is there an existing issue for this?

• I have searched the existing issues

Environment

- Milvus version: 2.5.3
- Deployment mode(standalone or cluster): cluster
- MQ type(rocksmq, pulsar or kafka):    
- SDK version(e.g. pymilvus v2.0.0rc2): 2.5.3
- OS(Ubuntu or CentOS): 
- CPU/Memory: 
- GPU: 
- Others:

Current Behavior

After a collection is created, when I click 'Data', it always fails to load sparse data with an error message as attached. This does't occur in earlier version.

Please see attached.

Expected Behavior

Sparse vector can be displayed correctly along with other fields in ATTU

Steps To Reproduce

Any collection with a sparse vector should be able to reproduce it.

Maybe later version of attu will support it.

Check your attu version. @shanghaikid is there a specific version recommeneded?

Also please upgrate milvus to 2.5.4 since we fix some critical issue here

[shanghaikid]

what is your attu version？ the error shows that you are trying to get milvus generated spares vector field which is not allowed to retrieve from milvus.

We upgraded Milvus 2.4.11 to 2.5.3, not a clean install of Milvus. So probably Attu not upgraded.

[shanghaikid]

ok, please try the latest attu, it should be good.

[lingvisa]

Yes. Attu is updated to 2.5.0 now. Now in the UI sparse vector isn't displayed at all, while the old version displays sparse vectors as one of the fields. Is this intended?

attu won't display vector generated by milvus.

The error shows it. @zhengbuqian can you confirm this?

I updated to ATTU 2.5.0. Now only dense vector is displayed, and sparse vector isn't displayed. Just want to confirm whether this is intended. In previous versions, both vectors are displayed.

maybe we should ignore sparse vector field if data in data out is enabled?

Yes sparse vector field generated by Milvus BM25 function(introduced in Milvus 2.5) should not be displayed. It is some internal representation and makes little sense to the user.

@lingvisa is your sparse vector field the output field of a BM25 Function(as described in https://milvus.io/docs/full-text-search.md#Create-a-collection-for-full-text-search)? if so then it is expected behavior it is not displayed. If the sparse vector is a normal one generated and inserted from the client, then it should be displayed.
