The token indices sequence length is longer than the specified maximum sequence length error occurs when the token indices sequence length exceeds the specified maximum sequence length. This is a common problem when working with large text inputs. To fix the token indices sequence length is longer than the specified maximum sequence length error, truncate the … Read more
The RuntimeError: The size of tensor a (4000) must match the size of tensor b (512) at non-singleton dimension 1 error occurs when you exceed the maximum input length limitation, usually 512 tokens. To fix the RuntimeError: The size of tensor a (4000) must match the size of tensor b (512) at non-singleton dimension 1 error, you … Read more
The BERT Error – Some weights of the model checkpoint at were not used when initializing BertModel occurs when you try to load a pre-trained BERT model and face an error related to mismatched weights. How to fix it? Verify the pre-trained model checkpoint Ensure you are using the correct pre-trained model checkpoint for the BERT … Read more
To encode multiple sentences using the transformers.BertTokenizer, you can use the BertTokenizer.from_pretrained() method. The BertTokenizer.from_pretrained() method is a class method in the Hugging Face Transformers library that allows you to load a pre-trained tokenizer for the BERT model. This tokenizer converts text input into a format the BERT model can understand. To use BertTokenizer.from_pretrained() method, … Read more
The BertTokenizer.from_pretrained() method is a class method in the Hugging Face Transformers library that allows you to load a pre-trained tokenizer for the BERT model. This tokenizer converts text input into a format the BERT model can understand. To use BertTokenizer.from_pretrained(), first make sure you have the transformers library installed: pip install transformers In the … Read more
The ImportError: cannot import name ‘SAVE_STATE_WARNING’ from ‘torch.optim.lr_scheduler’ occurs when there is a mismatch between your PyTorch version and the code you are running. To fix the ImportError: cannot import name ‘SAVE_STATE_WARNING’ from ‘torch.optim.lr_scheduler’ error, update it using pip command: pip install –upgrade torch. You can check your current PyTorch version by running the following … Read more
Python raises TypeError: forward() got an unexpected keyword argument ‘labels’ error in Pytorch BERT when you pass an argument called ‘labels’ to the forward() method, but the method does not expect this argument. To fix the TypeError: forward() got an unexpected keyword argument ‘labels’, remove the ‘labels’ argument from the forward() method. If you are using … Read more
The RuntimeError: 0D or 1D target tensor expected, multi-target not supported error is raised when the target tensor (labels) has an incorrect shape. In PyTorch, the CrossEntropyLoss expects the target tensor to have a 1D shape. To fix the RuntimeError: 0D or 1D target tensor expected, multi-target not supported, make sure your labels tensor has the correct … Read more
To disable the TOKENIZERS_PARALLELISM warning in the Hugging Face transformers library, you can set the TOKENIZERS_PARALLELISM environment variable to true or false before importing the library. import os # Set the TOKENIZERS_PARALLELISM environment variable os.environ[“TOKENIZERS_PARALLELISM”] = “false” # Now import the Transformers library from transformers import AutoTokenizer, AutoModelForSequenceClassification # Your code continues here… Setting the … Read more
To download a model from Hugging Face, you don’t need to do anything special because the models are automatically cached locally when you first use them. So, to download a model, all you have to do is run the code provided on the model card. But to do that, you must use the Transformers library. … Read more
The collate_fn is a function used to merge a list of samples into a mini-batch of Tensor(s) that can be loaded into the model. It is used in conjunction with DataLoader class in PyTorch. How to Use ‘collate_fn’ with dataloaders Step 1: Define a custom ‘collate_fn’ function Define a function that takes a list of … Read more
