# solo-learn
A library of self-supervised methods for unsupervised visual representation learning powered by PyTorch Lightning.
We aim at providing SOTA self-supervised methods in a comparable environment while, at the same time, implementing training tricks.
The library is self-contained, but it is possible to use the models outside of solo-learn. **More details in our [paper](#citation)**.

## Extra flavor
### Backbones
* [ResNet](https://arxiv.org/abs/1512.03385)
* [WideResNet](https://arxiv.org/abs/1605.07146)
* [ViT](https://arxiv.org/abs/2010.11929)
* [Swin](https://arxiv.org/abs/2103.14030)
* [PoolFormer](https://arxiv.org/abs/2111.11418)
* [ConvNeXt](https://arxiv.org/abs/2201.03545)
### Data
* Increased data processing speed by up to 100% using [Nvidia Dali](https://github.com/NVIDIA/DALI).
* Flexible augmentations.
### Evaluation
* Online linear evaluation via stop-gradient for easier debugging and prototyping (optionally available for the momentum backbone as well).
* Standard offline linear evaluation.
* Online and offline K-NN evaluation.
* Automatic feature space visualization with UMAP.
### Training tricks
* All the perks of PyTorch Lightning (mixed precision, gradient accumulation, clipping, and much more).
* Channel last conversion
* Multi-cropping dataloading following [SwAV](https://arxiv.org/abs/2006.09882):
* **Note**: currently, only SimCLR, BYOL and SwAV support this.
* Exclude batchnorm and biases from weight decay and LARS.
* No LR scheduler for the projection head (as in SimSiam).
### Logging
* Metric logging on the cloud with [WandB](https://wandb.ai/site)
* Custom model checkpointing with a simple file organization.
---
## Requirements
* torch
* torchvision
* tqdm
* einops
* wandb
* pytorch-lightning
* lightning-bolts
* torchmetrics
* scipy
* timm
**Optional**:
* nvidia-dali
* matplotlib
* seaborn
* pandas
* umap-learn
---
## Installation
First clone the repo.
Then, to install solo-learn with [Dali](https://github.com/NVIDIA/DALI) and/or UMAP support, use:
```bash
pip3 install .[dali,umap,h5] --extra-index-url https://developer.download.nvidia.com/compute/redist
```
If no Dali/UMAP/H5 support is needed, the repository can be installed as:
```bash
pip3 install .
```
For local development:
```bash
pip3 install -e .[umap,h5]
# Make sure you have pre-commit hooks installed
pre-commit install
```
**NOTE:** if you are having trouble with dali, install it following their [guide](https://github.com/NVIDIA/DALI).
**NOTE 2:** consider installing [Pillow-SIMD](https://github.com/uploadcare/pillow-simd) for better loading times when not using Dali.
**NOTE 3:** Soon to be on pip.
---
## Training
For pretraining the backbone, follow one of the many bash files in `scripts/pretrain/`.
We are now using [Hydra](https://github.com/facebookresearch/hydra) to handle the config files, so the common syntax is something like:
```bash
python3 main_pretrain.py \
# path to training script folder
--config-path scripts/pretrain/imagenet-100/ \
# training config name
--config-name barlow.yaml
# add new arguments (e.g. those not defined in the yaml files)
# by doing ++new_argument=VALUE
# pytorch lightning's arguments can be added here as well.
```
After that, for offline linear evaluation, follow the examples in `scripts/linear` or `scripts/finetune` for finetuning the whole backbone.
For k-NN evaluation and UMAP visualization check the scripts in `scripts/{knn,umap}`.
**NOTE:** Files try to be up-to-date and follow as closely as possible the recommended parameters of each paper, but check them before running.

:rocket: methods where hyperparameters were heavily tuned.
:sleepy: ViT is very compute intensive and unstable, so we are slowly running larger architectures and with a larger batch size. Atm, total batch size is 128 and we needed to use float32 precision. If you want to contribute by running it, let us know!

## Training efficiency for DALI
We report the training efficiency of some methods using a ResNet18 with and without DALI (4 workers per GPU) in a server with an Intel i9-9820X and two RTX2080ti.
| Method | Dali | Total time for 20 epochs | Time for 1 epoch | GPU memory (per GPU) |
|--------------|:----------------:|:--------------------------:|:--------------------:|:---------------------:|
| Barlow Twins | :x: | 1h 38m 27s | 4m 55s | 5097 MB |
| |:heavy_check_mark:| 43m 2s | 2m 10s (56% faster) | 9292 MB |
| BYOL | :x: | 1h 38m 46s | 4m 56s | 5409 MB |
| |:heavy_check_mark:| 50m 33s | 2m 31s (49% faster) | 9521 MB |
| NNCLR | :x: | 1h 38m 30s | 4m 55s | 5060 MB |
| |:heavy_check_mark:| 42m 3s | 2m 6s (64% faster) | 9244 MB |
**Note**: GPU memory increase doesn't scale with the model, rather it scales with the number of workers.
