# Setup Horovod and OpenMPI in Q Blocks Instance

Horovod is a free and open-source software framework for distributed deep learning training using TensorFlow, Keras, PyTorch, and Apache MXNet.

Horovod is hosted under the Linux Foundation AI.

Setting up Horovod in your Q Blocks instance is as simple as running a single bash command.

We have prepared a quick and easy to use bash script that installs and configures Horovod along with openMPI in your instance.

Horovod uses openMPI for message passing during the distributed training process.

#### Follow the steps below for successful installation:

1. Go to your Q Blocks instance and open the bash terminal in it.
2. Run the following command:

```bash
wget https://www.qblocks.cloud/resources/setup-horovod.sh --no-check-certificate -O - | sh
```

#### The above command would perform the following tasks:

* Install any missing dependencies to build OpenMPI
* Install OpenMPI
* Install Horovod with support NCCL, Tensorflow and PyTorch

#### Installation can be verified by running the command:

```bash
horovodrun --help
```
