Having trouble creating metadata based on a dataframe about sdv

[fyy623]

fixed myself, try below:

metadata = SingleTableMetadata()
for col in list(train):
    metadata.add_column(column_name=col, sdtype='numerical', computer_representation='Float')

if os.path.exists("metadata.json"):
    os.remove("metadata.json")

metadata.save_to_json(filepath='metadata.json')

synthesizer = CTGANSynthesizer(
    metadata,
    epochs=500,
    verbose=True)

Hi @fyy623 glad you were able to fix it. Do feel free to file a new issue if you run into anything.

BTW I believe the issue was that you were passing in the metadata dictionary into CTGANSynthesizer. All SDV synthesizers expects you to pass in a SingleTableMetadata object, not a dictionary. For more info, you can see the resources below:

• SingleTableMetadata API
