May 24, 2019 · torchtext.data.iterator.BucketIterator I am writing some sentiment analysis code using torchtext bucketiterator and surprised by the behavior of how we make dataset for example if we have from torchtext.data import TabularDataset TEXT = data.Field(tokenize = 'spacy', include_lengths = True, preprocessing= lambda x: preprocessor(x), lower=True) LABEL = data.LabelField(dtype = torch.long) INDEX ...

Nov 13, 2020 · Using PyTorch Text TabularDataset with PyTorchText Bucket Iterator: Here I use the built-in PyTorchText TabularDataset that reads data straight from local files without the need to create a PyTorch Dataset class. Then I follow same steps as in the previous part to show how nicely text examples are grouped together.

30.03.2019 · Well, if it’s of any use, I’ve posted my code below. Since this doesn’t use any fancy torch or even numpy stuff, it’s almost trivial. In my case, inputs is a list of N encoded sequences with a maximum length max_seq_len that are padded if needed.lengths is a list with lengths for each of the N sequences (max_seq_len - padding) – I have my own vectorizer which returns …
