# You have just found DeepPoseKit.








DeepPoseKit is a software toolkit with a high-level API for 2D pose estimation of user-defined keypoints using deep learning—written in Python and built using [Tensorflow](https://github.com/tensorflow/tensorflow) and [Keras](https://www.tensorflow.org/guide/keras). Use DeepPoseKit if you need:



- tools for annotating images or video frames with user-defined keypoints

- a straightforward but flexible data augmentation pipeline using the [imgaug package](https://github.com/aleju/imgaug)

- a Keras-based interface for initializing, training, and evaluating pose estimation models

- easy-to-use methods for saving and loading models and making predictions on new data



DeepPoseKit is designed with a focus on *usability* and *extensibility*, as being able to go from idea to result with the least possible delay is key to doing good research.



DeepPoseKit is currently limited to *individual pose estimation*. If individuals can be easily distinguished visually (i.e., they have differently colored bodies or are marked in some way), then multiple individuals can simply be labeled with separate keypoints (head1, tail1, head2, tail2, etc.). Otherwise DeepPoseKit can be extended to multiple individuals by first localizing, tracking, and cropping individuals with additional software such as [idtracker.ai](https://idtracker.ai/), [pinpoint](https://github.com/jgraving/pinpoint), or [Tracktor](https://github.com/vivekhsridhar/tracktor).



Localization (without tracking) can also be achieved with deep learning software like [keras-retinanet](https://github.com/fizyr/keras-retinanet), the [Tensorflow Object Detection API](https://github.com/tensorflow/models/tree/master/research/object_detection), or [MatterPort's Mask R-CNN](https://github.com/matterport/Mask_RCNN).

# How to use DeepPoseKit



DeepPoseKit is designed for easy use. For example, training and saving a model requires only a few lines of code:

```python

from deepposekit.io import DataGenerator, TrainingGenerator

from deepposekit.models import StackedDenseNet



data_generator = DataGenerator('/path/to/annotation_data.h5')

train_generator = TrainingGenerator(data_generator)

model = StackedDenseNet(train_generator)

model.fit(batch_size=16, n_workers=8)

model.save('/path/to/saved_model.h5')

```

Loading a trained model and running predictions on new data is also straightforward. For example, running predictions on a new video:

```python

from deepposekit.models import load_model

from deepposekit.io import VideoReader



model = load_model('/path/to/saved_model.h5')

reader = VideoReader('/path/to/video.mp4')

predictions = model.predict(reader)

```



## Using DeepPoseKit is a 4-step process:



- **1.** [Create an annotation set](https://github.com/jgraving/DeepPoseKit/blob/master/examples/step1_create_annotation_set.ipynb) Open In Colab

- **2.** [Annotate your data](https://github.com/jgraving/DeepPoseKit/blob/master/examples/step2_annotate_data.ipynb) with our built-in GUI (no Colab support)

- **3.** [Select and train](https://github.com/jgraving/DeepPoseKit/blob/master/examples/step3_train_model.ipynb) one our [pose estimation models](http://jakegraving.com/DeepPoseKit/html/deepposekit/models/index.html) including [`StackedDenseNet`](http://jakegraving.com/DeepPoseKit/html/deepposekit/models/StackedDenseNet.html), [`StackedHourglass`](http://jakegraving.com/DeepPoseKit/html/deepposekit/models/StackedHourglass.html), [`DeepLabCut`](http://jakegraving.com/DeepPoseKit/html/deepposekit/models/DeepLabCut.html), and [`LEAP`](http://jakegraving.com/DeepPoseKit/html/deepposekit/models/LEAP.html). Open In Colab

- **4.** Use the trained model to:

	- a) [Initialize keypoints for unannotated data](https://github.com/jgraving/DeepPoseKit/blob/master/examples/step4a_initialize_annotations.ipynb) for faster annotations with *active learning*. Open In Colab

	- b) [Predict on new data and refine the training set](https://github.com/jgraving/DeepPoseKit/blob/master/examples/step4b_predict_new_data.ipynb) to improve performance. Open In Colab



## For more details:



- See [our example notebooks](https://github.com/jgraving/deepposekit/blob/master/examples/)

- Check the [documentation](http://docs.deepposekit.org)

- Read [our paper](https://doi.org/10.7554/eLife.47994)



## "I already have annotated data"



DeepPoseKit is designed to be extensible, so loading data in other formats is possible.



If you have annotated data from DeepLabCut (http://deeplabcut.org), try [our (experimental) example notebook ](https://github.com/jgraving/DeepPoseKit/blob/master/examples/deeplabcut_data_example.ipynb) for loading data in this format. Open In Colab



Have data in another format? You can write your own custom generator to load it.

Check out the [example for writing custom data generators](https://github.com/jgraving/DeepPoseKit/blob/master/examples/custom_data_generator.ipynb). Open In Colab



# Installation



DeepPoseKit requires [Tensorflow](https://github.com/tensorflow/tensorflow) for training and using pose estimation models. [Tensorflow](https://github.com/tensorflow/tensorflow) should be manually installed, along with dependencies such as CUDA and cuDNN, before installing DeepPoseKit:



- [Tensorflow Installation Instructions](https://www.tensorflow.org/install)

- Any Tensorflow version >=1.13.0 should be compatible (including 2.0).



DeepPoseKit has only been tested on Ubuntu 18.04, which is the recommended system for using the toolkit. 



Install the latest stable release with pip:

```bash

pip install --update deepposekit

```



Install the latest development version with pip:

```bash

pip install --update git+https://www.github.com/jgraving/deepposekit.git

```



You can download example datasets from our [DeepPoseKit Data](https://github.com/jgraving/deepposekit-data) repository:

```bash

git clone https://www.github.com/jgraving/deepposekit-data

```



## Installing with Anaconda on Windows



To install DeepPoseKit on Windows, you must first manually install `Shapely`, one of the dependencies for the [imgaug package](https://github.com/aleju/imgaug):

```bash

conda install -c conda-forge shapely

```

We also recommend installing DeepPoseKit from within Python rather than using the command line, either from within Jupyter or another IDE, to ensure it is installed in the correct working environment:

```python

import sys

!{sys.executable} -m pip install --update deepposekit

```
