Identifying optimal techniques to compress models by reducing the number of parameters in them is important in order to reduce memory, battery, and hardware consumption without sacrificing accuracy, deploy lightweight models on device, and guarantee privacy with private on-device computation. most recent commit 2 years ago. This includes engineering topics like model quantization and binarization, more research-oriented topics like knowledge distillation, as well as well-known-hacks. This post covers model inference optimization or compression in breadth and hopefully depth as of March 2021. Working on that was a bit of a realization. Reproducible Model Zoo Variety of state of the art pretrained video models and their associated benchmarks that are ready to use. To actually compress the model, the existing libraries, such as PyTorch or Tensorflow, should have a `SparseConvolutional` (hypothetical) layer to perform sparse matrix computation in an optimized way. for each batch of L rows in weight matrix W (dim=out_ch*in_ch): reconstruct column at that index from the current L-row submatrix of W, transpose this column and vstack it to matrix At, pick out corr. and Fixed-point Activations, A Targeted Acceleration and Compression Framework for Low bit Neural Artificial Neural Network (ANN) based codecs have shown remarkable outcomes for compressing images. Built using PyTorch. Our toolkit provides a compression algorithm via a knowledge distillation [12] based on training procedure without any external training data. They are listed here for convenience (along with some notes). model compression based on pytorch (1quantization: 8/4/2bits(dorefa)ternary/binary value(twn/bnn/xnor-net)2 pruning: normalregular and group convolutional channel pruning3 group convolution structure4batch-normalization folding for binary value of feature(A)). It can make a model suitable for production that would have previously been too expensive, too slow, or too large. In the case of the LeNet-5 model, the Patient Knowledge Distillation for BERT Model Compression Knowledge distillation for BERT model Installation Run command below to install the environment conda install pytorch torchvision cudatoolkit=10.0 -c pytorch pip install -r requirements.txt Training Objective Function L = (1 - \alpha) L_CE + \alpha * L_DS + \beta * L_PT, Now, we try to run inference on this set of compressed weights. Secondly, the remaining Make sure you have installed Docker Engine and nvidia-docker. weights and activations are quantized to 8-bit integers from 32-bit DeepSpeed reduces the number of GPUs for serving this model to 2 in FP16 with 1.9x faster latency. We train a third model which is the student model with a boost from the pre-trained Teacher model. Serving ML models in resource constrained mobile and real-time systems can be a real problem.

This is coherent with the size of the network since the embedding's sizes are 100 smaller. source, Uploaded Hinton Geoffrey, Oriol Vinyals, and Jeff Dean. In the end, the compressed size is printed. A Medium publication sharing concepts, ideas and codes. returns an output matrix where each column is a channel, and is thus chainable. 2022 Python Software Foundation In this paper, we add model compression, specifically Deep Compression, and further optimize Unlu's earlier work on arXiv, which efficiently deploys PyTorch models on MCUs. A tag already exists with the provided branch name. This branch is 13 commits ahead of 666DZY666:master. I invite you to dig deeper in the KDD2018 paper if you are interested in this type of cross model interactions. The framework provides a catalog of common model compression techniques abstracted using a consistent programming model. for each weight matrix, this prints its min, returns a tuple containing compressed format and size of the compressed weight in bytes. floating-point. Model CompressionPytorch This repository provides a toy tutorial of model compression including network pruning, knowledge distillation and quantization (MNN). In this blog I replicated a small part of this Ranking Distillation work on the Movielens 100K dataset. At its core if you are a bit familiar with the positive vs negative loss from using a log sigmoid loss, we pass the current batch of data through the teacher network and get candidate predictions, and use them to generate the teacher loss values. Compression / Decompression to_relative_csr(m, index_bits): row in input matrix and vstack to At, increment p_l and c_l for all rows that have the minimum col num, # at this point, should have At=(x*in_len) and B=(x*L), where x is nonzero count, call beco matmul to obtain U_l = At.T @ B (dim=in_len*L), hstack all U_l's to form matrix U (dim=in_len*k), TODO: support batch sizes that are not the entire length of input, NOTE TO SELF: when transcribing to C, fix & unroll L, # C = np.zeros((out_len, out_ch)) # calloc, # v's, c's, r's are stored as separate arrays, # tail condition can be written separately, # need to be uint32; length prealloc to L, # At = np.vstack([At, m[:, min_val]]) # would probably require a transpose step, # in C skip this step and modify convolution sampling instead, # obviously skipped in C since array writes are in-place. Efficient Video Components Video-focused fast and efficient components that are easy to use. In addition to CPUs, Intel Extension for . Only when I close my app and run it again the all memory is freed. All we have to do is define a modified loss function that sums up the student and teacher losses and let gradient descent do its magic.

We are using the movielens 100K dataset and only using the movie/user interaction. The initial experiments showed up to 32x compression rates in large transformer architectures such as BERT. This is approximately 1 / 9 of the original model, if the original model were to be stored in 8 bits. Model Loading load_pruned(path): load a pruned pytorch state file by applying weight mask. We need to explain the strategy we are going to use to teach some of that Dark Knowledge from the Teacher model to the Student model with distillation. memory footprint was reduced by 12.45x, and the inference speed was boosted by data structures for sparse matrices, which store only nonzero weights (without In this repository, you can find the source code of the paper "Deep Compression for PyTorch Model Deployment on Microcontrollers". Geoffrey Hintons talk at the Deep Learning Summit 2018 about using Knowledge Distillation (KD) led me to look up the current state of the art for another class of problems: Recommender systems (RecSys). There are some popular model compression algorithms built-in in NNI. Base Model: VGG16, ResNet34. The framework of choice these days seems to be Spotlight from Maciej Kula. ACM, 2018. Are you sure you want to create this branch? Model compression promises savings on the inference time, power efficiency and model size. To tackle that, I followed on the footsteps of the RD paper and used the elegant PyTorch API for building this KD in RecSys. Probably a future post. Part V: combining compressions. py3, Status: For users to compress their models, they only need to add several lines in their code. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. This extra information supposedly should improve the predictive powers of the Student model with distillation while keeping the model size at the same level as the Student model without distillation. Networks, Structured Compression by Unstructured Pruning for Sparse Quantized This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. Compared with PyTorch, DeepSpeed achieves 2.3x faster inference speed using the same number of GPUs. model-compression " . torch v1.7 . After pruning, the model has a global sparsity of 91.26%, indicating only 8.74% of the values are nonzero. Training the model. calculates fully connected layer on input matrix, where each row is a channel. scikit-learn or just use docker $ docker pull tonyapplekim/deepcompressionpytorch Usage Pruning $ python pruning.py This command trains LeNet-300-100 model with MNIST dataset prunes weight values that has low absolute value retrains the model with MNIST dataset prints out non-zero statistics for each weights in the layer Code: In the following code, we will import some libraries from which we can normalize our pretrained model. Third, the MAP@5 of the student model is lower than the teacher model (0.050 vs 0.073). It uses pre-trained models and evaluation tools to compare learned methods with traditional codecs. Mapping of floating point tensors to quantized tensors is customizable with user defined observer/fake-quantization blocks. Support low-precision and mixed-precision quantization, with hardware implementation through TVM. This model uses an embeddings-based model structure: For the loss we use a method similar to the following negative logarithmic of the likelihood function. Maciej Kula, Spotlight, 2017 https://github.com/maciejkula/spotlight. This work follows the paper Efficient Neural Network Deployment for Microcontroller by Hasan Unlu. Aug 5, 2021 Many of the optimizations will eventually be included in future PyTorch mainline releases, but the extension allows PyTorch users to get up-to-date features and optimizations more quickly. DA2Lite is an automated model compression toolkit for PyTorch. BitPack is a practical tool to efficiently save ultra-low precision/mixed-precision quantized models. impacting performance and accuracy).

Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Ask Question Asked 1 year, 4 months ago. First, we prune the del model torch.cuda.empty_cache () but GPU memory doesn't change, then i tried to do this: model.cpu () del model When I move model to CPU, GPU memory is freed but CPU memory increase. Makes it easy to use all the PyTorch-ecosystem components. pytorchpytorchONNX. Trainer supports the following options: Pruning makes a model sparse. $ conda activate model_compression $ conda install -c pytorch cudatooolkit= ${cuda_version} After environment setup, you can validate the code by the following commands. Even if KD is a solid conceptual framework for distilling knowledge from one model to a small model, applying it on Ranking tasks for recommender systems is not a trivial task. microcontrollers (MCUs), has recently been attracting more attention than ever. max, total number of elements, and sparsity. Copy PIP instructions, Pre-pruned pytorch model compression toolkit, View statistics for this project via Libraries.io, or by using our public dataset on Google BigQuery, License: Other/Proprietary License (Proprietary). However, existing model compression algorithms mainly use simulation to check the performance (e.g., accuracy) of compressed model. efficient convolution algorithm with a batch size B on a NORMAL weight matrix. However, in this we use the Teacher models predictions on the data that we feed to the student model as well. Currently only PyTorch version has been supported, and TensorFlow version will be supported in future. 2019 represent an image as a laplacian pyramid, with a loss component that serves to force sparsity in the higher resolution levels. Model Speedup The final goal of model compression is to reduce inference latency and model size. The goal is to generate 3 models: Student model, Student model with distillation, and Teacher Model from the Movielens 100K dataset and compare their MAP@K metric as well as their physical disk size. Important note: to use this, you must first prune your model, for which the methods vary from model to model. Combining large-batch optimization and communication compression . Normalization in PyTorch is done using torchvision.transform.Normalization () .This is used to normalize the data with mean and standard deviation. Distilling the knowledge in a neural network. arXiv preprint arXiv:1503.02531 (2015). encoder.0.2.bias). Developed and maintained by the Python community, for the Python community. The YAML file has two sections: pruners and policies. For the Teacher model, we pre-train it similar to the Student model but we use a larger network size to achieve a higher Mean Average Precision at K (MAP@K). Pruner supports the following methods: Usually, unstructured pruning gives more sparsity, but it doesn't support shrinking. More precisely we use the teachers loss in addition to the students loss to calculate and backpropagate the gradients in the Student models network. Modified 6 months ago. Neural network deployment on low-cost embedded systems, hence on One can easily mix quantized and floating point operations in a model. Shrinker is now experimental. returns global sparsity. In each attempt of training, memory is increasing all the time. converts m into the column-relative CSR format. note that using this for sparse matrix operations can be very inefficient. weights W is an array of CSR matrix (v, c, r) pairs, each corresponding to a output channel. Dataset: CIFAR10. (Optional for nvidia gpu) Install cudatoolkit. "outputs/exp_dset=verso_ssd,prune_preset=verso2/best.th", high level simulation of beco matrix multiply behavior. Users could further use NNI's auto tuning power to find the best compressed model, which is detailed in Auto Model Compression. To do that we need to mix the two losses we get from both model in the loss function. Uploaded Most code are originally from other repositories, while i modified on my experiment. pip install model-compression-777 -i https://pypi.org/simple. We then try to compress all of the weights, excluding biases. $ conda activate model_compression $ conda install -c pytorch cudatooolkit= $ {cuda_version} After environment setup, you can validate the code by the following commands. 2022 Deep AI, Inc. | San Francisco Bay Area | All rights reserved.

I highly recommend it, the API design is easy to use and it lets the user customize most aspects that we are going to need for this experiment. WHAT IS THE STATE OF NEURAL NETWORK PRUNING? Model compression reduces CPU/GPU time, memory usage, and disk storage. We did not cover how to improve this setup with weighting the Teachers model loss, or by only considering the top-k recommendations of the teachers model. The first challenge is that we are working at a lower level of abstraction than the usual fit/predict API that exists in higher level libraries such as Scikit-learn and Keras. Please try enabling it if you encounter problems. dependent packages 22 total releases 50 most recent commit a day ago Efficient Ai Backbones 2,691 returns an output matrix where each row is a channel, and is thus chainable. neural nets. This is because the change needed to implement this KD is at the loss function formulation itself. First, we add some extra functions for the decoder and encoder. For the Student model we use a traditional approach using training data with data labels and a single ranking loss. DenseNet), networks that have only one last fully-connected layer, network blocks that has element-wise sum followed by skip connections (e.g. If anyone notices anything incorrect, please let me know. cfg = [192, 160, 96, 192, 192, 192, 192, 192], cfg = [256, 256, 256, 512, 512, 512, 1024, 1024], 2WA, W(32/8/4/2bits, /) A(32/8/4/2bits, /), 3/tricksW/W/gradstesaturate_stesoft_steW_gap()W/ABN_momentum(<0.9)AB-A-C-PC-B-A-Pacc, 4modelfilterN(8,16), 5batch normalizationmodelBN > convwbABN > convb), ShuffleNetShuffle, 314bits//2DLMNNNCNNTensorRT, cfg = [32, 64, 128, 256, 256, 256, 512, 1024].
