Fix DatasetGenerationError

✅ Solution

DatasetGenerationError in PEFT usually arises from incorrectly formatted data or mismatched column names within your training dataset when fine-tuning with multiple adapters. Ensure your dataset's column names precisely match the expected input names (e.g., "input_ids", "attention_mask", "labels") for each adapter's specific task, and verify that the data types are compatible. Padding or truncation might also be necessary to standardize sequence lengths before merging dataframes from different adapters into a single, unified dataset.
