Hi @<1594863230964994048:profile|DangerousBee35> , I've never heard of that - does it happen to you? If so, in which agent version, and can you share a script to reproduce?

Hi @<1594863230964994048:profile|DangerousBee35> ,

i run

    from clearml import Task
    import pandas as pd
    task = Task.init(project_name='examples', task_name='Artifacts with data_')

    df = pd.DataFrame(
        {
            'num_legs': [2, 4, 8, 0],
            'num_wings': [2, 0, 0, 0],
            'num_specimen_seen': [10, 2, 1, 8]
        },
        index=['falcon', 'dog', 'spider', 'fish']
    )

    # Register Pandas object as artifact to watch
    # (it will be monitored in the background and automatically synced and uploaded)
    task.upload_artifact('data_train', df, metadata={'counting': 'legs', 'max legs': 69})

and all works, can you try running it? Do you have other script I can try? Whats the clearml version you are using?

After running your suggestion (which worked), i'll be more accurate, the issue is with datasets and not tasks. try running this:

from clearml import Task, Dataset
import pandas as pd

task = Task.init(project_name='examples', task_name='Artifacts with data_')
ds = Dataset.create(dataset_project="examples", dataset_name="test", use_current_task=True)

df = pd.DataFrame(
    {
        'num_legs': [2, 4, 8, 0],
        'num_wings': [2, 0, 0, 0],
        'num_specimen_seen': [10, 2, 1, 8]
    },
    index=['falcon', 'dog', 'spider', 'fish']
)

# Register Pandas object as artifact to watch
# (it will be monitored in the background and automatically synced and uploaded)
task.upload_artifact('data_train', df, metadata={'counting': 'legs', 'max legs': 69})
ds = Dataset.get(ds.id)

I'm getting this error:

ValueError: invalid literal for int() with base 10: 'train'

which is caused by the artifact starting with "data_".
using clearml version: 1.14.4

Hi @<1594863230964994048:profile|DangerousBee35> , I can get reproduce the issue, will keep you posted about it

I'm currently overcoming it by just adding a "_ " ("data_ something" -> "_data_something")
