Great! + +Note that if you find OOM, perhaps you need to enable [Low VRAM mode](low_vram.md), and perhaps you also need to use smaller batch size and gradient accumulation. Or you may also want to use some “advanced” tricks like sliced attention or xformers. For example: + +```python +# Configs +batch_size = 1 + +# Misc +trainer = pl.Trainer(gpus=1, precision=32, callbacks=[logger], accumulate_grad_batches=4) # But this will be 4x slower +``` + +Note that training with 8 GB laptop GPU is challenging. We will need some GPU memory optimization at least as good as automatic1111’s UI. This may require expert modifications to the code. + +### Screenshots + +The training is fast. After 4000 steps (batch size 4, learning rate 1e-5, about 50 minutes on PCIE 40G), the results on my machine (in an output folder "image_log") is + +Control: + +![img](../github_page/t/ip.png) + +Prompt: + +![img](../github_page/t/t.png) + +Prediction: + +![img](../github_page/t/op.png) + +Ground Truth: + +![img](../github_page/t/gt.png) + +Note that the SD's capability is preserved. Even training on this super aligned dataset, it still draws some random textures and those snow decorations. (Besides, note that the ground truth looks a bit modified because it is converted from SD's latent image.) + +Larger batch size and longer training will further improve this. Adequate training will make the filling perfect. + +Of course, training SD to fill circles is meaningless, but this is a successful beginning of your story. + +Let us work together to control large models more and more. + +## Other options + +Beyond standard things, we also provide two important parameters "sd_locked" and "only_mid_control" that you need to know. + +### only_mid_control + +By default, only_mid_control is False. When it is True, you will train the below architecture. + +![img](../github_page/t6.png) + +This can be helpful when your computation power is limited and want to speed up the training, or when you want to facilitate the "global" context learning. Note that sometimes you may pause training, set it to True, resume training, and pause again, and set it again, and resume again. + +If your computation device is good, perhaps you do not need this. But I also know some artists are willing to train a model on their laptop for a month - in that case, perhaps this option can be useful. + +### sd_locked + +By default, sd_locked is True. When it is False, you will train the below architecture. + +![img](../github_page/t7.png) + +This will unlock some layers in SD and you will train them as a whole. + +This option is DANGEROUS! If your dataset is not good enough, this may downgrade the capability of your SD model. + +However, this option is also very useful when you are training on images with some specific style, or when you are training with special datasets (like medical dataset with X-ray images or geographic datasets with lots of Google Maps). You can understand this as simultaneously training the ControlNet and something like a DreamBooth. + +Also, if your dataset is large, you may want to end the training with a few thousands of steps with those layer unlocked. This usually improve the "problem-specific" solutions a little. You may try it yourself to feel the difference. + +Also, if you unlock some original layers, you may want a lower learning rate, like 2e-6. + +## More Consideration: Sudden Converge Phenomenon and Gradient Accumulation + +![img](../github_page/ex1.jpg) + +Because we use zero convolutions, the SD should always be able to predict meaningful images. (If it cannot, the training has already failed.) + +You will always find that at some iterations, the model "suddenly" be able to fit some training conditions. This means that you will get a basically usable model at about 3k to 7k steps (future training will improve it, but that model after the first "sudden converge" should be basically functional). + +Note that 3k to 7k steps is not very large, and you should consider larger batch size rather than more training steps. If you can observe the "sudden converge" at 3k step using batch size 4, then, rather than train it with 300k further steps, a better idea is to use 100× gradient accumulation to re-train that 3k steps with 100× batch size. Note that perhaps we should not do this *too* extremely (perhaps 100x accumulation is too extreme), but you should consider that, since "sudden converge" will *always* happen at that certain point, getting a better converge is more important. + +Because that "sudden converge" always happens, lets say "sudden converge" will happen at 3k step and our money can optimize 90k step, then we have two options: (1) train 3k steps, sudden converge, then train 87k steps. (2) 30x gradient accumulation, train 3k steps (90k real computation steps), then sudden converge. + +In my experiments, (2) is usually better than (1). However, in real cases, perhaps you may need to balance the steps before and after the "sudden converge" on your own to find a balance. The training after "sudden converge" is also important. + +But usually, if your logic batch size is already bigger than 256, then further extending the batch size is not very meaningful. In that case, perhaps a better idea is to train more steps. I tried some "common" logic batch size at 64 or 96 or 128 (by gradient accumulation), it seems that many complicated conditions can be solved very well already. diff --git

the function of key frame translation. Full code for full video translation will be released upon the publication of the paper. +### To avoid overload, we set limitations to the **maximum frame number** (8) and the maximum frame resolution (512x768). +### The running time of a video of size 512x640 is about 1 minute per keyframe under T4 GPU. +### How to use: +1. **Run 1st Key Frame**: only translate the first frame, so you can adjust the prompts/models/parameters to find your ideal output appearance before run the whole video. +2. **Run Key Frames**: translate all the key frames based on the settings of the first frame +3. **Run All**: **Run 1st Key Frame** and **Run Key Frames** +4. **Run Propagation**: propogate the key frames to other frames for full video translation. This part will be released upon the publication of the paper. +### Tips: +1. This method cannot handle large or quick motions where the optical flow is hard to estimate. **Videos with stable motions are preferred**. +2. Pixel-aware fusion may not work for large or quick motions. +3. Try different color-aware AdaIN settings and even unuse it to avoid color jittering. +4. `revAnimated_v11` model for non-photorealstic style, `realisticVisionV20_v20` model for photorealstic style. +5.

+ + + + + +## Highlights + +- **Flexible & Modular design** + + We decompose the end-to-end optical flow framework into five components: + + feature extraction, feature enhancement, feature matching, flow propagation and flow refinement. + + One can easily construct a customized optical flow model by combining different components. + +- **High accuracy** + + With only one refinement, GMFlow outperforms 31-refinements RAFT on the challenging Sintel benchmark. + +- **High efficiency** + + A basic GMFlow model (without refinement) runs at 57ms (V100) or 26ms (A100) for Sintel data (436x1024). + + GMFlow gains more speedup than RAFT on high-end GPUs (e.g., A100) since GMFlow doesn't require a large number of sequential computation. + + GMFlow also simplifies backward flow computation without requiring to forward the network twice. The bidirectional flow can be used for occlusion detection with forward-backward consistency check. + +

+ + + + +## Installation + +Our code is based on pytorch 1.9.0, CUDA 10.2 and python 3.8. Higher version pytorch should also work well. + +We recommend using [conda](https://www.anaconda.com/distribution/) for installation: + +``` +conda env create -f environment.yml +conda activate gmflow +``` + +## Demos + +All pretrained models can be downloaded from [google drive](https://drive.google.com/file/d/1d5C5cgHIxWGsFR1vYs5XrQbbUiZl9TX2/view?usp=sharing). + + + +You can run a trained model on a sequence of images and visualize the results: + +``` +CUDA_VISIBLE_DEVICES=0 python main.py \ +--inference_dir demo/sintel_market_1 \ +--output_path output/gmflow-norefine-sintel_market_1 \ +--resume pretrained/gmflow_sintel-0c07dcb3.pth +``` + +You can also predict bidirectional flow with `--pred_bidir_flow` enabled and use `--fwd_bwd_consistency_check` for forward-backward consistency check. More examples can be found in [scripts/demo.sh](scripts/demo.sh). + + + +## Datasets + +The datasets used to train and evaluate GMFlow are as follows: + +* [FlyingChairs](https://lmb.informatik.uni-freiburg.de/resources/datasets/FlyingChairs.en.html#flyingchairs) +* [FlyingThings3D](https://lmb.informatik.uni-freiburg.de/resources/datasets/SceneFlowDatasets.en.html) +* [Sintel](http://sintel.is.tue.mpg.de/) +* [KITTI](http://www.cvlibs.net/datasets/kitti/eval_scene_flow.php?benchmark=flow) +* [HD1K](http://hci-benchmark.iwr.uni-heidelberg.de/) + +By default the dataloader [datasets.py](data/datasets.py) assumes the datasets are located in folder `datasets` and are organized as follows: + +``` +datasets +├── FlyingChairs_release +│   └── data +├── FlyingThings3D +│   ├── frames_cleanpass +│   ├── frames_finalpass +│   └── optical_flow +├── HD1K +│   ├── hd1k_challenge +│   ├── hd1k_flow_gt +│   ├── hd1k_flow_uncertainty +│   └── hd1k_input +├── KITTI +│   ├── testing +│   └── training +├── Sintel +│   ├── test +│   └── training +``` + +It is recommended to symlink your dataset root to `datasets`: + +```shell +ln -s $YOUR_DATASET_ROOT datasets +``` + +Otherwise, you may need to change the corresponding paths in [datasets.py](data/datasets.py). + + + +## Evaluation + +You can evaluate a trained GMFlow model by running: + +``` +CUDA_VISIBLE_DEVICES=0 python main.py --eval --val_dataset things sintel --resume pretrained/gmflow_things-e9887eda.pth +``` + +More evaluation scripts can be found in [scripts/evaluate.sh](scripts/evaluate.sh). + + + +For submission to Sintel and KITTI online test sets, you can run [scripts/submission.sh](scripts/submission.sh). + + + +## Training + +All training scripts on FlyingChairs, FlyingThings3D, Sintel and KITTI datasets can be found in [scripts/train_gmflow.sh](scripts/train_gmflow.sh) and [scripts/train_gmflow_with_refine.sh](scripts/train_gmflow_with_refine.sh). + +Note that the basic GMFlow model (without refinement) can be trained on 4x 16GB V100 GPUs. For training GMFlow with refinement, 8x 16GB V100 or 4x 32GB V100 or 4x 40GB A100 GPUs are required by default. You may need to tune the batch size and training iterations according to your hardware. + + + +We support using tensorboard to monitor and visualize the training process. You can first start a tensorboard session with + +```shell +tensorboard --logdir checkpoints +``` + +and then access [http://localhost:6006](http://localhost:6006) in your browser. + + + +## Citation + +If you find our work useful in your research, please consider citing our paper: + +``` +@inproceedings{xu2022gmflow, + title={GMFlow: Learning Optical Flow via Global Matching}, + author={Xu, Haofei and Zhang, Jing and Cai, Jianfei and Rezatofighi, Hamid and Tao, Dacheng}, + booktitle={Proceedings of the IEEE/CVF Conference on Computer Vision and Pattern Recognition}, + pages={8121-8130}, + year={2022} +} +``` + + + +## Acknowledgements + +This project would not have been possible without relying on some awesome repos : [RAFT](https://github.com/princeton-vl/RAFT), [LoFTR](https://github.com/zju3dv/LoFTR), [DETR](https://github.com/facebookresearch/detr), [Swin](https://github.com/microsoft/Swin-Transformer), [mmdetection](https://github.com/open-mmlab/mmdetection) and [Detectron2](https://github.com/facebookresearch/detectron2/blob/main/projects/TridentNet/tridentnet/trident_conv.py).
