🔥🔥🔥 LaMa generalizes surprisingly well to much higher resolutions (~2k❗️) than it saw during training (256x256), and achieves the excellent performance even in challenging scenarios, e.g. completion of periodic structures.[ Project page ] [ arXiv ] [ Supplementary ] [ BibTeX ] [ Casual GAN Papers Summary ]

❗️❗️❗️ All yandex dist links went bad, you can download the model from the google drive ❗️❗️❗️
Clone the repo:
git clone https://github.com/advimman/lama.git
There are three options of an environment:
Python virtualenv:
virtualenv inpenv --python=/usr/bin/python3
source inpenv/bin/activate
pip install torch==1.8.0 torchvision==0.9.0
cd lama
pip install -r requirements.txt
Conda
% Install conda for Linux, for other OS download miniconda at https://docs.conda.io/en/latest/miniconda.html
wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
bash Miniconda3-latest-Linux-x86_64.sh -b -p $HOME/miniconda
$HOME/miniconda/bin/conda init bash
cd lama
conda env create -f conda_env.yml
conda activate lama
conda install pytorch torchvision torchaudio cudatoolkit=10.2 -c pytorch -y
pip install pytorch-lightning==1.2.9
Docker: No actions are needed 🎉.
cd lama
export TORCH_HOME=$(pwd) && export PYTHONPATH=$(pwd)
1. Download pre-trained models
The best model (Places2, Places Challenge):
curl -LJO https://huggingface.co/smartywu/big-lama/resolve/main/big-lama.zip
unzip big-lama.zip
All models (Places & CelebA-HQ):
download [https://drive.google.com/drive/folders/1B2x7eQDgecTL0oh3LSIBDGj0fTxs6Ips?usp=drive_link]
unzip lama-models.zip
2. Prepare images and masks
Download test images:
unzip LaMa_test_images.zip
OR prepare your data:
1) Create masks named as `[images_name]_maskXXX[image_suffix]`, put images and masks in the same folder.
You can use the script for random masks generation.
Check the format of the files:
image1_mask001.png
image1.png
image2_mask001.png
image2.png
Specify image_suffix, e.g. .png or .jpg or _input.jpg in configs/prediction/default.yaml.
3. Predict
On the host machine:
python3 bin/predict.py model.path=$(pwd)/big-lama indir=$(pwd)/LaMa_test_images outdir=$(pwd)/output
OR in the docker
The following command will pull the docker image from Docker Hub and execute the prediction script
bash docker/2_predict.sh $(pwd)/big-lama $(pwd)/LaMa_test_images $(pwd)/output device=cpu
Docker cuda:
bash docker/2_predict_with_gpu.sh $(pwd)/big-lama $(pwd)/LaMa_test_images $(pwd)/output
4. Predict with Refinement
On the host machine:
python3 bin/predict.py refine=True model.path=$(pwd)/big-lama indir=$(pwd)/LaMa_test_images outdir=$(pwd)/output
Make sure you run:
cd lama
export TORCH_HOME=$(pwd) && export PYTHONPATH=$(pwd)
Then download models for perceptual loss:
mkdir -p ade20k/ade20k-resnet50dilated-ppm_deepsup/
wget -P ade20k/ade20k-resnet50dilated-ppm_deepsup/ http://sceneparsing.csail.mit.edu/model/pytorch/ade20k-resnet50dilated-ppm_deepsup/encoder_epoch_20.pth
⚠️ NB: FID/SSIM/LPIPS metric values for Places that we see in LaMa paper are computed on 30000 images that we produce in evaluation section below.
For more details on evaluation data check [Section 3. Dataset splits in Supplementary] ⚠️

Please check bash scripts for data preparation and mask generation from CelebaHQ section,
if you stuck at one of the following steps.
On the host machine:
# Make shure you are in lama folder
cd lama
export TORCH_HOME=$(pwd) && export PYTHONPATH=$(pwd)
# You need to prepare following image folders:
$ ls my_dataset
train
val_source # 2000 or more images
visual_test_source # 100 or more images
eval_source # 2000 or more images
# LaMa generates random masks for the train data on the flight,
# but needs fixed masks for test and visual_test for consistency of evaluation.
# Suppose, we want to evaluate and pick best models
# on 512x512 val dataset with thick/thin/medium masks
# And your images have .jpg extention:
python3 bin/gen_mask_dataset.py \
$(pwd)/configs/data_gen/random_<size>_512.yaml \ # thick, thin, medium
my_dataset/val_source/ \
my_dataset/val/random_<size>_512.yaml \# thick, thin, medium
--ext jpg
# So the mask generator will:
# 1. resize and crop val images and save them as .png
# 2. generate masks
ls my_dataset/val/random_medium_512/
image1_crop000_mask000.png
image1_crop000.png
image2_crop000_mask000.png
image2_crop000.png
# Generate thick, thin, medium masks for visual_test folder:
python3 bin/gen_mask_dataset.py \
$(pwd)/configs/data_gen/random_<size>_512.yaml \ #thick, thin, medium
my_dataset/visual_test_source/ \
my_dataset/visual_test/random_<size>_512/ \ #thick, thin, medium
--ext jpg
ls my_dataset/visual_test/random_thick_512/
image1_crop000_mask000.png
image1_crop000.png
image2_crop000_mask000.png
image2_crop000.png
# Same process for eval_source image folder:
python3 bin/gen_mask_dataset.py \
$(pwd)/configs/data_gen/random_<size>_512.yaml \ #thick, thin, medium
my_dataset/eval_source/ \
my_dataset/eval/random_<size>_512/ \ #thick, thin, medium
--ext jpg
# Generate location config file which locate these folders:
touch my_dataset.yaml
echo "data_root_dir: $(pwd)/my_dataset/" >> my_dataset.yaml
echo "out_root_dir: $(pwd)/experiments/" >> my_dataset.yaml
echo "tb_dir: $(pwd)/tb_logs/" >> my_dataset.yaml
mv my_dataset.yaml ${PWD}/configs/training/location/
# Check data config for consistency with my_dataset folder structure:
$ cat ${PWD}/configs/training/data/abl-04-256-mh-dist
train:
indir: ${location.data_root_dir}/train
indir: ${location.data_root_dir}/val
img_suffix: .png
visual_test:
indir: ${location.data_root_dir}/visual_test
img_suffix: .png
# Run training
python3 bin/train.py -cn lama-fourier location=my_dataset data.batch_size=10
# Evaluation: LaMa training procedure picks best few models according to
# scores on my_dataset/val/
# To evaluate one of your best models (i.e. at epoch=32)
# on previously unseen my_dataset/eval do the following
# for thin, thick and medium:
# infer:
python3 bin/predict.py \
model.path=$(pwd)/experiments/<user>_<date:time>_lama-fourier_/ \
indir=$(pwd)/my_dataset/eval/random_<size>_512/ \
outdir=$(pwd)/inference/my_dataset/random_<size>_512 \
model.checkpoint=epoch32.ckpt
# metrics calculation:
python3 bin/evaluate_predicts.py \
$(pwd)/configs/eval2_gpu.yaml \
$(pwd)/my_dataset/eval/random_<size>_512/ \
$(pwd)/inference/my_dataset/random_<size>_512 \
$(pwd)/inference/my_dataset/random_<size>_512_metrics.csv
OR in the docker:
TODO: train
TODO: eval
The following command will execute a script that generates random masks.
bash docker/1_generate_masks_from_raw_images.sh \
configs/data_gen/random_medium_512.yaml \
/directory_with_input_images \
/directory_where_to_store_images_and_masks \
--ext png
The test data generation command stores images in the format,
which is suitable for prediction.
The table below describes which configs we used to generate different test sets from the paper.
Note that we do not fix a random seed, so the results will be slightly different each time.
Feel free to change the config path (argument #1) to any other config in configs/data_gen
or adjust config files themselves.
Also you can override parameters in config like this:
python3 bin/train.py -cn <config> data.batch_size=10 run_title=my-title
Where .yaml file extension is omitted
Config names for models from paper (substitude into the training command):
* big-lama
* big-lama-regular
* lama-fourier
* lama-regular
* lama_small_train_masks
Which are seated in configs/training/folder
