AttributeError: 'Example' object has no attribute 'Insult' when build vocab using build_vocab() from torchtext

Question

I tried to build vocabulary using .build_vocab() from torchtext in colab. It returns the error message: AttributeError: 'Example' object has no attribute 'Insult'

My question is similar to @szymix12 s question. His answer is to make sure the order of the fields passed is the same as the csv headers. I confirm that the order I assign is correct. The csv data got two columns:"Insult" (LABEL) and "Comment"(TEXT). "Insult" is a binary label indicator (0 or 1).

The code is as below, I have also made a colab notebook. Feel free to run.

import os
import torch
from torchtext import data, datasets
from torchtext.utils import download_from_url

CSV_FILENAME = 'data.csv'
CSV_GDRIVE_URL = 'https://drive.google.com/open?id=1ctPKO-_sJbmc8RodpBZ5-3EyYBWlUy5Pbtjio5pyq00'
download_from_url(CSV_GDRIVE_URL, CSV_FILENAME)

TEXT = data.Field(tokenize = 'spacy', batch_first = True, lower=True)  #from torchtext import data
LABEL = data.LabelField(sequential=False, dtype = torch.float)

train = data.TabularDataset(path=os.path.join('/content', CSV_FILENAME),
                            format='csv',
                            fields = [('Insult', LABEL), ('Comment', TEXT)],
                            skip_header=True)


print(vars(train[0]),vars(train[1]),vars(train[2]))

TEXT.build_vocab(train)

You don't need to manually download&upload the file as suggested by @knoop. As I provided in my previous answer to your question, you should not use the link with open. You should change to uc?export=download instead. In this way, the correct CSV_GDRIVE_URL should be:

CSV_GDRIVE_URL = 'https://drive.google.com/uc?export=download&id=1eWMjusU3H34m0uml5SdJvYX6gQuB8zta'

Then, if you cat it, you'll get:

And TEXT.build_vocab(train) will run successfully.
