hello,

I am using weaviate-client==4.9.6 and I am getting the error AttributeError: ‘WeaviateClient’ object has no attribute ‘query’. When I run it with visual studio on my Windows device, I do not get such an error, but when I try to run it with visual studio and colab on my macOS device, I encounter this error. In which version can I use query? I would be very happy if you could help me.

Thanks

That sounds to me like in the installation where you are getting the error, you are using the current Python v4 API (as you mention, you retrieve a `WeaviateClient`object which is the case when using the v4 API).

In the v4 API, `query()` is to be called on `Collection` instances as described here:

> **[Migrate from v3 to v4 | Weaviate](https://weaviate.io/developers/weaviate/client-libraries/python/v3_v4_migration#interact-with-collections)**
>
> The current Python client version is v||site.pythonclientversion||

If you want to keep using your old code with the v3 API, you need to create instances of the deprecated `weaviate.Client()`. You can find details on that here:

hi @Kaan_Tiftikci !!

Welcome to our community 🤗

Can you share the code you are using? It seems like you are using different client versions.

This is python v3 client:

```python
v3c = weaviate.Client("http://localhost:8080")
v3c.query.get("Test", "text").do()

```

and this is the python v4 client:

```python
client = weaviate.connect_to_local()
collection = client.collections.get("Test")
collection.query.fetch_objects().objects

```

Note that the python v3 client is included in the python v4 client package. However, it is deprecated, a will be removed in future versions. Right now, if you instantiate a v3 client using the v4 client package, this warning will be printed:

> DeprecationWarning:  
> Python client v3 `weaviate.Client(...)` connections and methods are deprecated and will  
> be removed by 2024-11-30.
> 
> ```
> Upgrade your code to use Python client v4 `weaviate.WeaviateClient` connections and methods.
> - For Python Client v4 usage, see: https://weaviate.io/developers/weaviate/client-libraries/python
> - For code migration, see: https://weaviate.io/developers/weaviate/client-libraries/python/v3_v4_migration
> 
> If you have to use v3 code, install the v3 client and pin the v3 dependency in your requirements file: `weaviate-client>=3.26.7;<4.0.0`
> 
> ```

So this exact error you mentioned will surface when you call `.query` on the python v4 client:

```python
client.query

```

> AttributeError Traceback (most recent call last) Cell In[9], line 1 ----\> 1 client.query AttributeError: ‘WeaviateClient’ object has no attribute ‘query’

Let me know if this helps!

I just deleted it, it will be gone in the next release (4.10.0)
