So, I am working on a multi table SDV project. When I am importing **Metadata** from sdv multi table library, I am getting the following error as you can see the below screenshot:-

I have tried with the previous versions but still getting the same error. And when I try to import **MultiTableMetadata** instead of **Metadata** then it is getting imported but while detecting the data from dataframes, I am getting the following error as you can see in the below screenshots:-

About **MultiTableMetadata** import, nothing is provided in the documentation. I have checked the github for these methods as well, they are available there but still not able to import or work with them. I guess either SDV documentation or SDV code issue is there.  
Thanks.

Hi @bhavya.kundra,

Tl;dr Your issue is probably due to using an SDV Enterprise version older than 0.18.0. Upgrading should fix the issue. More details below.

# Details

The recommended approach is to use the `Metadata` class, as mentioned in the docs. (The `MultiTableMetadata` method is for older versions of SDV. It is not recommended anymore, and it does not appear in our docs anymore either.)

```python
from sdv.metadata import Metadata
from sdv.io.local import CSVHandler

# read all CSVs from a folder into Python (dataframe)
connector = CSVHandler()
data = connector.read(folder_name='project/data/')

# automatically infer metadata from the dataframe
metadata = Metadata.detect_from_dataframes(data)

```

The `Metadata` object is new, available starting from SDV Enterprise version 0.18.0 and above. You can run the commands below to see which version you have.

```python
import sdv

print(sdv.version.enterprise)

```

If the version is less than 0.18.0, I would recommend upgrading. Or if you are unable to upgrade, let us know.

# Resources

- **[Installation Instructions](https://docs.sdv.dev/sdv-enterprise/sdv-enterprise/installation#basic-instructions)** this is the same for first-time installation as well as upgrading to a later version
- **[Release Notes](https://docs.sdv.dev/sdv-enterprise/resources/release-notes#version-0.18.0-october-3-2024)** for SDV 0.18.0
