Torchtext TabularDataset datafields add annotation or multiple label

TEXT = = word_tokenize,  fix_length= 1000)
LABEL = = torch.float)

datafields = {
    "Phenotype": ("labels", LABEL), 
    "sequence": ("text", TEXT),
    "hybrids":("hybrids", HYBRIDS) 

In torchtext, I add a hybrids column, which is the sample’s names, in order to identify which prediction are made to the sample.
but no matter I define it LabelField or Field, it doesn’t work and raise error.
Is there some way to add a name column to the TabularDataset as naming of the sample, but not as label or text for training?

What kind of error are you seeing? Could you post the complete error message here, please?
