This repostiory contains our implementation of the paper: Lossy Compression for Lossless Prediction. That formalizes and empirically inverstigates unsupervised training for task-specific compressors.

Using the compressor

Using

If you want to use our compressor directly the easiest is to use the model from torch hub as seen in the google colab (or notebooks/Hub.ipynb) or th example below.

Installation details
pip install torch torchvision tqdm numpy compressai sklearn git+https://github.com/openai/CLIP.git

Using pytorch>1.7.1 : CLIP forces pytorch version 1.7.1, this is because it needs this version to use JIT. If you don't need JIT (no JIT by default) you can alctually use more recent versions of torch and torchvision pip install -U torch torchvision. Make sure to update after having isntalled CLIP.


import time

import torch
from sklearn.svm import LinearSVC
from torchvision.datasets import STL10

DATA_DIR = "data/"

# list available compressors. b01 compresses the most (b01 > b005 > b001)
torch.hub.list('YannDubs/lossyless:main') 
# ['clip_compressor_b001', 'clip_compressor_b005', 'clip_compressor_b01']

# Load the desired compressor and transformation to apply to images (by default on GPU if available)
compressor, transform = torch.hub.load('YannDubs/lossyless:main','clip_compressor_b005')

# Load some data to compress and apply transformation
stl10_train = STL10(
    DATA_DIR, download=True, split="train", transform=transform
)
stl10_test = STL10(
    DATA_DIR, download=True, split="test", transform=transform
)

# Compresses the datasets and save them to file (this requires GPU)
# Rate: 1506.50 bits/img | Encoding: 347.82 img/sec
compressor.compress_dataset(
    stl10_train,
    f"{DATA_DIR}/stl10_train_Z.bin",
    label_file=f"{DATA_DIR}/stl10_train_Y.npy",
)
compressor.compress_dataset(
    stl10_test,
    f"{DATA_DIR}/stl10_test_Z.bin",
    label_file=f"{DATA_DIR}/stl10_test_Y.npy",
)

# Load and decompress the datasets from file the datasets (does not require GPU)
# Decoding: 1062.38 img/sec
Z_train, Y_train = compressor.decompress_dataset(
    f"{DATA_DIR}/stl10_train_Z.bin", label_file=f"{DATA_DIR}/stl10_train_Y.npy"
)
Z_test, Y_test = compressor.decompress_dataset(
    f"{DATA_DIR}/stl10_test_Z.bin", label_file=f"{DATA_DIR}/stl10_test_Y.npy"
)

# Downstream STL10 evaluation. Accuracy: 98.65% | Training time: 0.5 sec
clf = LinearSVC(C=7e-3)
start = time.time()
clf.fit(Z_train, Y_train)
delta_time = time.time() - start
acc = clf.score(Z_test, Y_test)
print(
    f"Downstream STL10 accuracy: {acc*100:.2f}%.  \t Training time: {delta_time:.1f} "
)

Minimal training code

Training

If your goal is to look at a minimal version of the code to simply understand what is going on, I would highly recommend starting from notebooks/minimal_compressor.ipynb (or google colab link above). This is a notebook version of the code provided in Appendix E.7. of the paper, to quickly train and evaluate our compressor.

Installation details
  1. pip install git+https://github.com/openai/CLIP.git
  2. pip uninstall -y torchtext (probably not necessary but can cause issues if got installed as wrong pytorch version)
  3. pip install scikit-learn==0.24.2 lightning-bolts==0.3.4 compressai==1.1.5 pytorch-lightning==1.3.8

Using pytorch>1.7.1 : CLIP forces pytorch version 1.7.1 you should be able to use a more recent versions. E.g.:

  1. pip install git+https://github.com/openai/CLIP.git
  2. pip install -U torch torchvision scikit-learn lightning-bolts compressai pytorch-lightning

Results from the paper

We provide scripts to essentially replicate some results from the paper. The exact results will be a little different as we simplified and cleaned some of the code to help readability. All scripts can be found in bin and run using the command bin/*/<experiment>.sh.

Installation details
  1. Clone repository
  2. Install PyTorch >= 1.7
  3. pip install -r requirements.txt

Other installation

  • For the bare minimum packages: use pip install -r requirements_mini.txt instead.
  • For conda: use conda env update --file requirements/environment.yaml.
  • For docker: we provide a dockerfile at requirements/Dockerfile.

Notes

  • CLIP forces pytorch version 1.7.1, this is because it needs this version to use JIT. We don't use JIT so you can alctually use more recent versions of torch and torchvision pip install -U torch torchvision.
  • For better logging: hydra and pytorch lightning logging don't work great together, to have a better logging experience you should comment out the folowing lines in pytorch_lightning/__init__.py :
if not _root_logger.hasHandlers():
     _logger.addHandler(logging.StreamHandler())
     _logger.propagate = False

Test installation

To test your installation and that everything works as desired you can run bin/test.sh, which will run an epoch of BICNE and VIC on MNIST.


Scripts details

All scripts can be found in bin and run using the command bin/*/<experiment>.sh. This will save all results, checkpoints, logs... The most important results (including summary resutls and figures) will be saved at results/exp_<experiment>. Most important are the summarized metrics results/exp_<experiment>*/summarized_metrics_merged.csv and any figures results/exp_<experiment>*/*.png.

The key experiments that that do not require very large compute are:

  • VIC/VAE on rotation invariant Banana distribution: bin/banana/banana_viz_VIC.sh
  • VIC/VAE on augmentation invariant MNIST: bin/mnist/augmist_viz_VIC.sh
  • CLIP experiments: bin/clip/main_linear.sh

By default all scripts will log results on weights and biases. If you have an account (or make one) you should set your username in conf/user.yaml after wandb_entity:, the passwod should be set directly in your environment variables. If you prefer not logging, you can use the command bin/*/<experiment>.sh -a logger=csv which changes (-a is for append) the default wandb logger to a csv logger.

Generally speaking you can change any of the parameters either directly in conf/**/<file>.yaml or by adding -a to the script. We are using Hydra to manage our configurations, refer to their documentation if something is unclear.

If you are using Slurm you can submit directly the script on servers by adding a config file under conf/slurm/<myserver>.yaml, and then running the script as bin/*/<experiment>.sh -s <myserver>. For example configurations files for slurm see conf/slurm/vector.yaml or conf/slurm/learnfair.yaml. For more information check the documentation from submitit's plugin which we are using.


VIC/VAE on rotation invariant Banana

Command:

bin/banana/banana_viz_VIC.sh

The following figures are saved automatically at results/exp_banana_viz_VIC/**/quantization.png. On the left we see the quantization of the Banana distribution by a standard compressor (called VAE in code but VC in paper). On the right, by our (rotation) invariant compressor (VIC).

Standard compression of Banana Invariant compression of Banana

VIC/VAE on augmentend MNIST

Command:

bin/banana/augmnist_viz_VIC.sh

The following figure is saved automatically at results/exp_augmnist_viz_VIC/**/rec_imgs.png. It shows source augmented MNIST images as well as the reconstructions using our invariant compressor.

Invariant compression of augmented MNIST

CLIP compressor

Command:

bin/clip/main_small.sh

The following table comes directly from the results which are automatically saved at results/exp_clip_bottleneck_linear_eval/**/datapred_*/**/results_predictor.csv. It shows the result of compression from our CLIP compressor on many datasets.

Cars196 STL10 Caltech101 Food101 PCam Pets37 CIFAR10 CIFAR100
Rate [bits] 1471 1342 1340 1266 1491 1209 1407 1413
Test Acc. [%] 80.3 98.5 93.3 83.8 81.1 88.8 94.6 79.0

Note: ImageNet is too large for training a SVM using SKlearn. You need to run MLP evaluation with bin/clip/clip_bottleneck_mlp_eval. Also you have to download ImageNet manually.

    Ever Use a Projection Head?

    Hi Yann,

    Did you ever use a project head [1] (i.e., a multi-layer perceptron) to transform the output of the encoder?

    If I understand correctly, you directly feed the output of the encoder (e.g., a pre-trained ResNet model) into the rate estimator?

    Thanks!

  • Efficient way to integrate lossyless into a PyTorch Dataset subclass

    Efficient way to integrate lossyless into a PyTorch Dataset subclass

    Hey @YannDubs,

    I recently discovered your paper and find the idea very interesting. Therefore, I would like to integrate lossyless into a project I am currently working on. However, there are two requirements/presuppositions in my project that your compressor on PyTorch Hub does not cover as far as I understand it:

    • I assume that the training data do not fit into memory so I cannot decompress the entire dataset at once.
    • Because I cannot load the entire data into memory and shuffle them there, I need access to individual samples of the dataset (for random permutations) without touching the rest of the data (or as little as possible).

    Basically, I would like to integrate lossyless into a subclass of PyTorch's Dataset that implements the __getitem__(index) interface. Before I start experimenting on my own and potentially overlook something that you already thought about, I wanted to ask you if you already considered approaches how to integrate your idea into a PyTorch Dataset.

    Looking forward to a discussion!
