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

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

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 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?

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?
