In the ever-evolving landscape of artificial intelligence, maintaining the reproducibility of experiments is immensely important. This guide walks you through the process of installing NNCF (Neural Network Compression Framework) and applying it to create sparse neural network models. Buckle up, as we dive into the world of neural network pruning and optimizing!
Step 1: Install NNCF
The first step involves installing NNCF and applying a patch to modify the `sparsity_magnitude_algo.py` file. Follow these instructions:
- Clone the NNCF repository:
git clone https://github.com/your-username/nncf.git
cd nncf
git checkout 9c2845eeb38b4ab1b6d4ca19e31a1886e5bdf17c
def sparsify_params(self):
from collections import OrderedDict
sparse_sd = OrderedDict()
with torch.no_grad():
for sparse_info in self.sparsified_module_info:
for n, m in self.model.named_modules():
if m == sparse_info.module:
sparse_sd[n + '.weight'] = m.weight * sparse_info.operand.binary_mask
model_sd = self.model.state_dict()
for k, v in sparse_sd.items():
assert k in model_sd, "key does not exist!"
model_sd[k] = sparse_sd[k]
self.model.load_state_dict(model_sd)
Step 2: Fork the Transformers Repository
The next step is to fork the transformers library and check out a specific branch:
- Clone the transformers repository:
git clone https://github.com/vuiseng9/transformers.git
cd transformers
git checkout gen-hybrid-sparse
Step 3: Configure Your Environment
After setting up NNCF and the transformers library, configure your environment using the following path: `transformers/examples/pytorch/question-answering/gen-hybrid-sparse/vscode-launch.json`.
Key Content Structure
Here’s what your project structure should resemble post-setup:
- gen_hybrid_sparse/
- 90pc_sparse-02_head-0512_ffnn/
- 90pc_sparse-02_head-0512_ffnn-8bit.onnx
- ir/
- 90pc_sparse-02_head-0512_ffnn-8bit.bin
- 90pc_sparse-02_head-0512_ffnn-8bit.mapping
- 90pc_sparse-02_head-0512_ffnn-8bit.xml
- 90pc_unstructured_sparse/
- 90pc_unstructured_sparse-8bit.onnx
- ir/
- 90pc_unstructured_sparse-8bit.bin
- 90pc_unstructured_sparse-8bit.mapping
- 90pc_unstructured_sparse-8bit.xml
- 90pc_sparse-02_head-0512_ffnn/
Troubleshooting
If you encounter issues during installation or model fine-tuning, consider these troubleshooting suggestions:
- Ensure that all dependencies are installed correctly.
- Double-check the branch and commit you are checking out in the Git repositories.
- Review your directory structure to confirm that it matches the expected setup.
- If you face Python-related errors, ensure that your environment is activated and configured properly.
- Refer to the documentation of NNCF or Transformers for detailed information.
