This gives the pre-softmax confidence for 4 anchor boxes situated at each site of a 37 x 37 grid imposed on the image, one confidence score for each of the 21 classes. The first dimension is the batch dimension. Likewise, 'ssd_300_vgg/block4_box/Reshape:0' has shape [None, 37, 37, 4, 4] and encodes the (cx, cy) center shift and rescaling (sw, sh) relative to each anchor box. Refer to the [SSD-VGG paper](https://arxiv.org/abs/1512.02325) to understand how these are computed. The other 10 tensors are defined similarly."

+
+This is an introduction to the [Azure Machine Learning](https://docs.microsoft.com/en-us/azure/machine-learning/service/) Reinforcement Learning (Public Preview) using the [Ray](https://github.com/ray-project/ray/) framework.
+
+Using these samples, you will be able to do the following.
+
+1. Use an Azure Machine Learning workspace, set up virtual network and create compute clusters for running Ray.
+2. Run some experiments to train a reinforcement learning agent using Ray and RLlib.
+

+
+## Prerequisites
+
+To make use of these samples, you need the following.
+
+* A Microsoft Azure subscription.
+* A Microsoft Azure resource group.
+* An Azure Machine Learning Workspace in the resource group. Please make sure that the VM sizes `STANDARD_NC6` and `STANDARD_D2_V2` are supported in the workspace's region.
+* A virtual network set up in the resource group.
+  * A virtual network is needed for the examples training on multiple compute targets.
+  * The [devenv_setup.ipynb](setup/devenv_setup.ipynb) notebook shows you how to create a virtual network. You can alternatively use an existing virtual network, make sure it's in the same region as workspace is.
+  * Any network security group defined on the virtual network must allow network traffic on ports used by Azure infrastructure services. This is described in more detail in the [devenv_setup.ipynb](setup/devenv_setup.ipynb) notebook.
+
+
+## Setup
+
+You can run these samples in the following ways.
+
+* On an Azure ML Compute Instance or Notebook VM.
+* On a workstation with Python and the Azure ML Python SDK installed.
+
+### Azure ML Compute Instance or Notebook VM
+#### Update packages
+
+
+We recommend that you update the required Python packages before you proceed. The following commands are for entering in a Python interpreter such as a notebook.
+
+```shell
+# We recommend updating pip to the latest version.
+!pip install --upgrade pip
+# Update matplotlib for plotting charts
+!pip install --upgrade matplotlib
+# Update Azure Machine Learning SDK to the latest version
+!pip install --upgrade azureml-sdk
+# For Jupyter notebook widget used in samples
+!pip install --upgrade azureml-widgets
+# For Tensorboard used in samples
+!pip install --upgrade azureml-tensorboard
+# Install Azure Machine Learning Reinforcement Learning SDK
+!pip install --upgrade azureml-contrib-reinforcementlearning
+```
+
+### Your own workstation
+#### Install/update packages
+
+For a local workstation, create a Python environment and install [Azure Machine Learning SDK](https://docs.microsoft.com/en-us/python/api/overview/azure/ml/install?view=azure-ml-py) and the RL SDK. We recommend Python 3.6 and higher.
+
+```shell
+# Activate your environment first.
+# e.g.,
+# conda activate amlrl
+# We recommend updating pip to the latest version.
+pip install --upgrade pip
+# Install/upgrade matplotlib for plotting charts
+pip install --upgrade matplotlib
+# Install/upgrade tensorboard used in samples
+pip install --upgrade tensorboard
+# Install/upgrade Azure ML SDK to the latest version
+pip install --upgrade azureml-sdk
+# For Jupyter notebook widget used in samples
+pip install --upgrade azureml-widgets
+# For Tensorboard used in samples
+pip install --upgrade azureml-tensorboard
+# Install Azure Machine Learning Reinforcement Learning SDK
+pip install --upgrade azureml-contrib-reinforcementlearning
+# To use the notebook widget, you may need to register and enable the Azure ML extensions first.
+jupyter nbextension install --py --user azureml.widgets
+jupyter nbextension enable --py --user azureml.widgets
+```
