TF2DeepFloorplan

This repo contains a basic procedure to train and deploy the DNN model suggested by the paper 'Deep Floor Plan Recognition using a Multi-task Network with Room-boundary-Guided Attention'. It rewrites the original codes from zlzeng/DeepFloorplan into newer versions of Tensorflow and Python.
Network Architectures from the paper,

Additional feature (pygame)

Requirements

OS	Hardware	Application	Command
Ubuntu	CPU	Model Development	`pip install -e .[tfcpu,dev,testing,linting]`
Ubuntu	GPU	Model Development	`pip install -e .[tfgpu,dev,testing,linting]`
MacOS	M1 Chip	Model Development	`pip install -e .[tfmacm1,dev,testing,linting]`

Agnostic	...	Docker	(to be updated)
Ubuntu	GPU	Notebook	`pip install -e .[tfgpu,jupyter]`
Ubuntu	GPU	Game	`pip install -e .[tfgpu,game]`

How to run?

Install packages.

# Option 1
python -m venv venv
source venv/bin/activate
pip install --upgrade pip setuptools wheel
# Option 2 (Preferred)
conda create -n venv python=3.8 cudatoolkit=10.1 cudnn=7.6.5
conda activate venv
# common install
pip install -e .[tfgpu,api,dev,testing,linting]

According to the original repo, please download r3d dataset and transform it to tfrecords r3d.tfrecords. Friendly reminder: there is another dataset r2v used to train their original repo's model, I did not use it here cos of limited access. Please see the link here zlzeng/DeepFloorplan#17.
Run the train.py file to initiate the training, model checkpoint is stored as log/store/G and weight is in model/store,

python -m dfp.train [--batchsize 2][--lr 1e-4][--epochs 1000]
[--logdir 'log/store'][--modeldir 'model/store']
[--save-tensor-interval 10][--save-model-interval 20]
[--tfmodel 'subclass'/'func'][--feature-channels 256 128 64 32]
[--backbone 'vgg16'/'mobilenetv1'/'mobilenetv2'/'resnet50']
[--feature-names block1_pool block2_pool block3_pool block4_pool block5_pool]

for example,

python -m dfp.train --batchsize=4 --lr=5e-4 --epochs=100
--logdir=log/store --modeldir=model/store

Run Tensorboard to view the progress of loss and images via,

tensorboard --logdir=log/store

Convert model to tflite via convert2tflite.py.

python -m dfp.convert2tflite [--modeldir model/store]
[--tflitedir model/store/model.tflite]
[--loadmethod 'log'/'none'/'pb']
[--quantize][--tfmodel 'subclass'/'func']
[--feature-channels 256 128 64 32]
[--backbone 'vgg16'/'mobilenetv1'/'mobilenetv2'/'resnet50']
[--feature-names block1_pool block2_pool block3_pool block4_pool block5_pool]

Download and unzip model from google drive,

gdown https://drive.google.com/uc?id=1czUSFvk6Z49H-zRikTc67g2HUUz4imON # log files 112.5mb
unzip log.zip
gdown https://drive.google.com/uc?id=1tuqUPbiZnuubPFHMQqCo1_kFNKq4hU8i # pb files 107.3mb
unzip model.zip
gdown https://drive.google.com/uc?id=1B-Fw-zgufEqiLm00ec2WCMUo5E6RY2eO # tfilte file 37.1mb
unzip tflite.zip

Deploy the model via deploy.py, please be aware that load method parameter should match with weight input.

python -m dfp.deploy [--image 'path/to/image']
[--postprocess][--colorize][--save 'path/to/output_image']
[--loadmethod 'log'/'pb'/'tflite']
[--weight 'log/store/G'/'model/store'/'model/store/model.tflite']
[--tfmodel 'subclass'/'func']
[--feature-channels 256 128 64 32]
[--backbone 'vgg16'/'mobilenetv1'/'mobilenetv2'/'resnet50']
[--feature-names block1_pool block2_pool block3_pool block4_pool block5_pool]

for example,

python -m dfp.deploy --image floorplan.jpg --weight log/store/G
--postprocess --colorize --save output.jpg --loadmethod log

Play with pygame.

python -m dfp.game

Docker for API

Build and run docker container. (Please train your weight, google drive does not work currently due to its update.)

docker build -t tf_docker -f Dockerfile .
docker run -d -p 1111:1111 tf_docker:latest
docker run --gpus all -d -p 1111:1111 tf_docker:latest

# special for hot reloading flask
docker run -v ${PWD}/src/dfp/app.py:/src/dfp/app.py -v ${PWD}/src/dfp/deploy.py:/src/dfp/deploy.py -d -p 1111:1111 tf_docker:latest
docker logs `docker ps | grep "tf_docker:latest"  | awk '{ print $1 }'` --follow

Call the api for output.

curl -H "Content-Type: application/json" --request POST  \
  -d '{"uri":"https://cdn.cnn.com/cnnnext/dam/assets/200212132008-04-london-rental-market-intl-exlarge-169.jpg","colorize":1,"postprocess":0}' \
  http://0.0.0.0:1111/uri --output /tmp/tmp.jpg


curl --request POST -F "file=@resources/30939153.jpg" \
  -F "postprocess=0" -F "colorize=0" http://0.0.0.0:1111/upload --output out.jpg

If you run app.py without docker, the second curl for file upload will not work.

Google Colab

Click on and authorize access.
Run the first 2 code cells for installation.
Go to Runtime Tab, click on Restart runtime. This ensures the packages installed are enabled.
Run the rest of the notebook.

How to Contribute?

Git clone this repo.
