##### This work and code is developed by the awesome team of Awni et al, StanfordML Group. I have just modified it to work with python3 and few other changes for my comfort of use.

## Install 

Clone the repository

```

git clone git@github.com:manideep2510/ECG-acquisition-classification.git

```

**Python 3.5 or higher is required to run the code. To test the code the with the pretrained models, Python 3.5 is the only one it supports**

Install the requirements (this may take a few minutes).

For CPU only support run

```

cd ecg

./setup.sh

```

To install with GPU support run

```

env TF=gpu ./setup.sh

```

## Training

In the repo root direcotry (`ecg`) make a new directory called `saved`.

```

mkdir saved

```

To train a model use the following command, replacing `path_to_config.json`

with an actual config:

```

python ecg/train.py path_to_config.json

```

Note that after each epoch the model is saved in

`ecg/saved/<experiment_id>/<timestamp>/<model_id>.hdf5`.

For an actual example of how to run this code on a real dataset, you can follow

the instructions in the cinc17 [README](examples/cinc17/README.md). This will

walk through downloading the Physionet 2017 challenge dataset and training and

evaluating a model.

## Testing

After training the model for a few epochs, you can make predictions with.

```

python ecg/predict.py <dataset>.json <model>.hdf5

```

replacing `<dataset>` with an actual path to the dataset and `<model>` with the

path to the model.
