QdrantDocumentStore `init` error

[bilgeyucel]

A community member reported an issue about QdrantDocumentStore. It raises a type error when initialized for some reason. I could reproduce the issue but don't have a clear idea of what is wrong. Can you guide us here @kacperlukawski?

Here's the discord thread: https://discord.com/channels/993534733298450452/1149609255062737028 Here's a colab notebook to reproduce the issue

Some more info. Here's how they initialize the document store:

  document_store = QdrantDocumentStore(
           location=":memory:",
           index="Document",
           embedding_dim=768,
           recreate_index=True,
           similarity="cosine"
      )

Some more context from our community member:

I have a suspicion what the problem is https://github.com/qdrant/qdrant-client released four days ago 1.5.0 and now you have to initialize Qdrant like this:

client = QdrantClient(":memory:")

client.add(
    collection_name="demo_collection",
    documents=docs,
    metadata=metadata,
    ids=ids
)

But QdrantDocumentStore initialises it with more parameters. So the versions do not fit anymore

Hey @TuanaCelik @bilgeyucel @MathiasSpanhove

Thanks for pointing it out

It seems that metadata argument was not passed correctly into the QdrantClient

Thank you @joein - I see there's a PR here which seems like will resolve this issue. Let us know if we have to inform people to update one of the packages 🙏

[kacperlukawski]

@TuanaCelik I'm already reviewing the PR and the new version will be released today. I'll let you know here and also answer on Discord.

[kacperlukawski]

@bilgeyucel @TuanaCelik We've just released version 1.0.8. This is a hotfix that allows using qdrant up to 1.4. There will be another release this week so that we can support Qdrant 1.5 as well. That requires fixing qdrant-client first.

[kacperlukawski]

The latest release, 1.0.10, allows using some newer versions of the qdrant-client.
