# Keras_Multi_GPU
Multi-GPU training for Keras

# Usage

```python
from multi_gpu import to_multi_gpu

# Add the one line code before model.compile()
model = to_multi_gpu(model,n_gpus=4) 
```

# Example

Environment:
  - Keras-2.0.4
  - Tensorflow-1.1.0
  - Ubuntu 14.04
  - 1080Ti, K80

Test on 2 1080Ti GPUs with:
```python
model = to_multi_gpu(model,n_gpus=2) 
```

```
$ CUDA_VISIBLE_DEVICES=0,1 python mnist_cnn.py
