Building a (Very Simple) Vector Store - But getting error - Help Needed

[mraguth]

In below example:
https://docs.llamaindex.ai/en/stable/examples/low_level/vector_store/?h=vector_store.add%28nodes%29

At

test_node = TextNode(id_="id1", text="hello world")
test_node2 = TextNode(id_="id2", text="foo bar")
test_nodes = [test_node, test_node2]

vector_store = VectorStore2()

I am getting error:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
Cell In[15], [line 1](vscode-notebook-cell:?execution_count=15&line=1)
----> [1](vscode-notebook-cell:?execution_count=15&line=1) vector_store = VectorStore2()

TypeError: Can't instantiate abstract class VectorStore2 without an implementation for abstract method 'client'

[dosubot[bot]]

To resolve the error "Can't instantiate abstract class VectorStore2 without an implementation for abstract method 'client'", you need to provide an implementation for the client method. Here's how you can do it:

from llama_index.vector_stores.qdrant.base import VectorStore2

class MyVectorStore(VectorStore2):
    @property
    def client(self):
        # Provide the implementation for the abstract method 'client'
        return None  # or return the actual client instance

# Now you can instantiate MyVectorStore
my_vector_store = MyVectorStore(
    collection_name="my_collection",
    url="http://localhost:6333",
    api_key="your_api_key",
    batch_size=100,
    parallel=True,
    max_retries=3,
    client_kwargs={},
    enable_hybrid=True,
    index_doc_id=True
)

# Example usage
test_node = TextNode(id_="id1", text="hello world")
test_node2 = TextNode(id_="id2", text="foo bar")
test_nodes = [test_node, test_node2]

# Add nodes to the vector store
my_vector_store.add(test_nodes)

In this example, MyVectorStore is a concrete subclass of VectorStore2 that provides an implementation for the client method. You can then instantiate MyVectorStore with the required parameters and use it to add nodes to the vector store ^[1][2][3].
