[Bug]: SPARSE_FLOAT_VECTOR FieldSchema cause error.(data type not supported)

[jaylee4274]

Is there an existing issue for this?

• I have searched the existing issues

Environment

- Milvus version: pymilvus 2.4.0, milvus 2.2.16
- Deployment mode(standalone or cluster): standalone
- MQ type(rocksmq, pulsar or kafka):    
- SDK version(e.g. pymilvus v2.0.0rc2):
- OS(Ubuntu or CentOS): Windows
- CPU/Memory: 
- GPU: 4090(24gb)
- Others:

Current Behavior

Everytime I define Collection. FieldSchema(name="sparse_vector", dtype=DataType.SPARSE_FLOAT_VECTOR) causes RPC error.

Expected Behavior

Collection should be made by do this.

Steps To Reproduce

fields = [
    # Use auto generated id as primary key
    FieldSchema(
        name="pk", dtype=DataType.INT64, is_primary=True, auto_id=True, max_length=100
    ),
    FieldSchema(name="text", dtype=DataType.VARCHAR, max_length=8192),
    FieldSchema(name="sparse_vector", dtype=DataType.SPARSE_FLOAT_VECTOR),
    #FieldSchema(name="dense_vector", dtype=DataType.FLOAT_VECTOR, dim=1024),
]
schema = CollectionSchema(fields, "")
col = Collection("sparse_dense_demo", schema)

-> MilvusException: <MilvusException: (code=0, message=104 data type not supported)>

Anything else?

In my case, I don't think this error is from pymilvus version. I tried changing version several times.

PLZ help me.

@jaylee4274 could you please retry with latest milvus 2.4.20 and pymilvus release 2.4.13?
/assign @jaylee4274
/unassign

[yanliang567]

if you have to run on milvus 2.4.0, then please try to upgrade pymilvus to 2.4.0 as well
