Hello everyone!

I have created a custom dataset in the IOB tagging format. I want to follow the HF tutorial for Token Classification.

Sydney \_ \_ B-ORG  
Airport \_ \_ I-ORG  
announces \_ \_ O  
range \_ \_ O  
of \_ \_ O  
new \_ \_ O  
sustainability \_ \_ O  
goals \_ \_ O

Finland \_ \_ B-LOCATION  
is \_ \_ O  
on \_ \_ O  
track \_ \_ O  
to \_ \_ O  
be \_ \_ O  
carbon \_ \_ B-SUSTAINABILITY  
neutral \_ \_ I-SUSTAINABILITY  
by \_ \_ O  
2035 \_ \_ B-DATE

When I am loading my dataset with load\_dataset(). I only got “text”… But not the “labels”.

DatasetDict({  
train: Dataset({  
features: [‘text’],  
num\_rows: 285996  
})  
})

When I look at the structure in the data loader it’s as follows.

‘Sydney \_ \_ B-ORG’,  
‘Airport \_ \_ I-ORG’,  
‘announces \_ \_ O’,  
‘range \_ \_ O’,  
‘of \_ \_ O’,  
‘new \_ \_ O’,  
‘sustainability \_ \_ O’,  
‘goals \_ \_ O’,  
‘’,  
‘’,

Did I miss something?  
How can I create a similar structure of the WNUT 17 dataset (“id”, “ner\_tags”, and “tokens” ) in the tutorial?  
Thank you for your help.

Roman

Did you find a solution for that? I’m having the same trouble as well.
