Troubleshooting Common Issues

No matter how carefully you follow the recipe, sometimes a batch doesn’t turn out quite right. Here are some troubleshooting tips to resolve common issues you might face while using the model:

• High Validation Loss: Check your learning rate and batch sizes. Sometimes reducing the learning rate can help.
• Low Exact Match Rate: Ensure the dataset used for fine-tuning is well-prepared and represents the problem appropriately.
• Memory Errors: If you experience out-of-memory errors, consider reducing the batch size or number of gradient accumulation steps.
• Compatibility Issues: Verify that you are using compatible versions of the libraries: Transformers 4.24.0, PyTorch 1.13.0+cu117, Datasets 2.7.0.
