Can't handle vectors with dtype np.float32. np.float64 works just fine

[Nitinsiwach]

How to reproduce this bug?

jeopardy = client.collections.get("JeopardyQuestion")
uuid = jeopardy.data.insert(
    properties={
        "question": "This vector DB is OSS and supports automatic property type inference on import",
        "answer": "Weaviate",
    },
    vector= list(np.array([0.12345] * 1536, dtype = np.float32))
)

What is the expected behavior?

The data should insert just fine

What is the actual behavior?

1. If I insert one object with collections.data.insert Raises TypeError: Object of type float32 is not JSON serializable
2. If I insert using collections.data.insert_many. Doesnt use the vectors provided at all instead uses the default vectorizer provided in the yml used to create the client to vectorized the queries and the uses those vectors to store the object

Your 1. issue is fixed by this PR: #1077

However, I think your 2. issue may actually be because you have a default vectorizer set in your .yml config but you are creating your collection, as posted on SO, like so:

client.collections.create(
    name = "legal_sections", 
    properties = [
        wvc.config.Property(
            name="content",
            description="The actual section chunk that the answer is to be extracted from",
            data_type=wvc.config.DataType.TEXT,
            index_searchable=True,
            index_filterable=True,
            skip_vectorization=True,
            vectorize_property_name=False
        )
    ]
)

without specifying a vectoriser, so it defaults to the server default. Instead, you should add vectorizer_config=wvc.config.Configure.Vectorizer.none() to the client.collections.create(...) call.

v4.6.3 is now live, I would be grateful if you validate that it works then the issue can be closed 😁
