# MargiPose



Accompanying PyTorch code for the paper

["3D Human Pose Estimation with 2D Marginal Heatmaps"](https://arxiv.org/abs/1806.01484).



## Setup



Requirements:



* Linux

* Docker

* Docker Compose

* NVIDIA Container Toolkit (for GPU support)



### Configure the project



1. Copy `docker-compose.yml.example` to `docker-compose.yml`.

2. At this stage `docker-compose.yml` will contain example volume mounts for the datasets.

   You will need to edit the entries for datasets [that you have prepared](#prepare-datasets),

   and remove the others.



   For example, if you wish to use the MPI-INF-3DHP dataset, you must replace `/host/path/to/mpi3d`

   with the actual path to the prepared MPI-INF-3DHP data on your computer.



### Prepare datasets



You only need to prepare the datasets that you are interested in using.



#### Human3.6M



1. Use the scripts available at https://github.com/anibali/h36m-fetch to download

   and preprocess Human3.6M data.

2. Edit the volume mounts in `docker-compose.yml` so that the absolute location of

   the `processed/` directory created by h36m-fetch is bound to `/datasets/h36m`

   inside the Docker container.



#### MPI-INF-3DHP



1. Download [the original MPI-INF-3DHP dataset](http://gvv.mpi-inf.mpg.de/3dhp-dataset/).

2. Use the `src/margipose/bin/preprocess_mpi3d.py` script to preprocess the data.

3. Edit the volume mounts in `docker-compose.yml` so that the absolute location of

   the processed MPI-INF-3DHP data is bound to `/datasets/mpi3d` inside the Docker container.



#### MPII



1. Edit the volume mounts in `docker-compose.yml` so that the desired installation directory

   for the MPII Human Pose dataset is bound to `/datasets/mpii` inside the Docker container.

2. Run the following to download and install the MPII Human Pose dataset:

   ```

   $ ./run.sh bash

   $ chmod 777 -R /datasets/mpii

   $ python

   >>> from torchdata import mpii

   >>> mpii.install_mpii_dataset('/datasets/mpii')

   ```



### [Optional] Configure and run Showoff



Showoff is a display server which allows you to visualise model training progression.

The following steps guide you through starting a Showoff server and configuring

MargiPose to use it.



1. Change `POSTGRES_PASSWORD` in `showoff/postgres.env`. Using a randomly generated password is

   recommended.

2. Change `COOKIE_SECRET` in `showoff/showoff.env`. Once again, using a randomly generated

   value is recommended.

3. From a terminal in the showoff directory, run `docker-compose up -d showoff`. This will

   start the Showoff server.

4. Open [localhost:13000](http://localhost:13000) in your web browser.

5. Log in using the username "admin" and the password "password".

6. Change the admin password.

7. Open up `showoff/showoff-client.env` in a text editor.

8. From the Showoff account page, add a new API key. Copy the API key ID and secret key

   into `showoff-client.env` (you will need to uncomment the appropriate lines).



## Running scripts



A `run.sh` launcher script is provided, which will run any command within a Docker container

containing all of MargiPose's dependencies. Here are a few examples.



Train a MargiPose model on the MPI-INF-3DHP dataset:



```bash

./run.sh margipose train with margipose_model mpi3d

```



Train without pixel-wise loss term:



```bash

./run.sh margipose train with margipose_model mpi3d "model_desc={'settings': {'pixelwise_loss': None}}"

```



Evaluate a model's test set performance using the second GPU:



```bash

./run.sh margipose --device=cuda:1 eval --model margipose-mpi3d.pth --dataset mpi3d-test

```



Explore qualitative results with a GUI:



```bash

./run.sh margipose gui --model margipose-mpi3d.pth --dataset mpi3d-test

```



Run the project unit tests:



```bash

./run.sh pytest

```



## Pretrained models



Pretrained models are available for download:



* [margipose-mpi3d.pth](https://github.com/anibali/margipose/releases/download/v0.1.0/margipose-mpi3d.pth) [221.6 MB]

  * Trained on MPI-INF-3DHP and MPII examples

* [margipose-h36m.pth](https://github.com/anibali/margipose/releases/download/v0.1.0/margipose-h36m.pth) [221.6 MB]

  * Trained on Human3.6M and MPII examples



You can try out the pretrained model like so:



```bash

./run.sh margipose infer --model margipose-mpi3d.pth --image resources/man_running.jpg

```
