[Bug] Missing documentation on creation of ndarray for serialization

[SID262000]

Is this a new bug?

• I believe this is a new bug
• I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

The below line of code throws an error Type Error expected ndarray for serialization.

embeddings = model.encode(sentences)
embeddings.shape

Expected Behavior

We simply need to convert the model encoding to a list, which will resolve the above array.

Steps To Reproduce

Modify embeddings = model.encode(sentences) to embeddings = model.encode(sentences).tolist()

Relevant log output

No response

Environment

- **OS**:
- **Language version**:
- **Pinecone client version**:

I'm happy to work on this issue and update the documentation as well, feel free to assign it to me

Cc @jamescalam for review, Thanks

hey @SID262000 — I don't know what exactly is causing the issue here. Performing model.encode(sentences) (assuming sentences is a normal python list) should work — and it would output a numpy array, which allows us to do embeddings.shape as shown. Maybe there is something wrong with the sentences data type here?

Hi @jamescalam,
sentences in the above context is a list of strings
