Unable to retrieve metadata from model registry

W&B Help
1

I have some models saved to the Model Registry and I’m trying to access the Metadata however it’s only returning an empty dictionary. (I do have metadata saved to the models and they can be viewed from the web gui)

Code i’m using:

api = wandb.Api()
artifact = api.artifact('your-entity/wandb-registry-model/collection:latest') 
metadata = artifact.metadata
print(metadata)

I’ve also tried

run = wandb.init()
latest = run.use_artifact('your-entity/wandb-registry-model/collection:latest', type='model')
print(latest.metadata)

Both give the same empty dict output:

{}

However I can access other attributes such as artifact.name or artifact.aliases but not artifact.metadata

Hi Muqtasid:
Thank you for writing in! I’m wondering how you defined some metadata when you logged the artifact? Sharing the source code for reference, the artifact’s user_defined metadata is queryble. Could you share me a code snippet of how you init the artifact and it’s metadata?

this is how im initiating the run, im not adding any metadata to the init, but I’m using the ultralytics integration of wandb which is logging the metadata for each of the runs

   run = wandb.init(
                project="toll_booth", 
                name=f"experiment_{read_exp_num()}",
                id = f"experiment_{read_exp_num()}",
                config={
                    "epochs": self.no_epochs,
                    "batch_size": self.batch_size,
                    "weight_name": self.weight_name,
                    "data_path": self.data_path
                },
                job_type="training"
            )

Hi Muqtasid:
Have you had any success in the past using ultralytics integration of wandb and retrieved metadata?
