# 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. {% hint style="info" %} Installation and setup will take anywhere between 5-10 minutes. {% endhint %} #### 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 ``` If you face issues with the installation then reach out to us at . --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
