model-pruning

To prune a large language model without retraining, use one-shot pruning techniques like Wanda or SparseGPT, which apply sparsity to model weights using calibration data to reduce model size and accelerate inference.

Yes, you can apply Wanda pruning to a LLaMA-7B model to achieve 50% sparsity by passing your model and calibration data to the `wanda_prune` function with the sparsity parameter set to 0.5.

Model compression through sparsity reduces the number of non-zero weights in large language models. You need it when deploying models on constrained edge hardware that requires faster inference and smaller memory footprints.

Yes, this model pruning approach requires PyTorch, Transformers, and Accelerate libraries to perform tensor operations, load large language models, and manage hardware acceleration during the sparsity process.

One-shot model pruning for inference acceleration faces limitations in accuracy loss at higher sparsity ratios and requires hardware accelerators that specifically support and benefit from sparse matrix operations.

The best way to prepare calibration data for pruning a language model is to provide a representative sample of your target inference domain, allowing the pruning algorithm to accurately evaluate weight importance and minimize accuracy loss.
