import Azure HnswVectorSearchAlgorithmConfiguration comes Error: cannot import name 'HnswVectorSearchAlgorithmConfiguration'

Here is the reference document I follow with:

from azure.search.documents.models import Vector
from azure.search.documents.indexes.models import (  
    SearchIndex,  
    SearchField,  
    SearchFieldDataType,  
    SimpleField,  
    SearchableField,  
    SearchIndex,

    VectorSearch, 
    HnswVectorSearchAlgorithmConfiguration

At first, I faced import error which is about import Vector. I saw its solution on stackoverflow by updating azure.search.documents to the version ==11.4.0b6; While HnswVectorSearchAlgorithmConfiguration would be alwasy error no matter which version I used. I’ve tried azure.search.documents 11.4.0b6 and 11.4.0b4

If the import error remain unsolved, the folling part would be error too.

vector_search = VectorSearch(

    algorithm_configurations=[

        HnswVectorSearchAlgorithmConfiguration(

            name="my-vector-config",

            kind="hnsw",

            parameters={

                "m": 4,

                "efConstruction": 400,
                "efSearch": 500,
                "metric": "cosine"
            }
        )
    ]
)

I also tried to walkaround by import hnswlib, but it didn’t work…
