AllenNLP

A Apache 2.0 natural language processing toolkit using state-of-the-art deep learning models.

Setting up a development environment

DeepQA is built using Python 3. The easiest way to set up a compatible environment is to use Conda. This will set up a virtual environment with the exact version of Python used for development along with all the dependencies needed to run DeepQA.

1. Download and install Conda.

2. Create a Conda environment with Python 3.

   conda create -n allennlp python=3.5
   

3. Now activate the Conda environment.

   source activate allennlp
   

4. Install the required dependencies.

   ./scripts/install_requirements.sh
   

5. Visit http://pytorch.org/ and install the relevant pytorch package.

6. Set the PYTHONHASHSEED for repeatable experiments.

   export PYTHONHASHSEED=2157
   

You should now be able to test your installation with pytest -v. Congratulations!

Setting up a Kubernetes development environment

1. Follow the instructions for installing and setting up Kubernetes.

2. Fill in the yaml file. You need to add:

   • The name of the job, under the metadata: heading.
   • The namespace you wish to run in under the metadata: heading. To see which namespaces are available, run kubectl get ns .
   • Your contact name (first bit of your email) under labels.contact:.

3. Run kubectl create -f /path/to/kubernetes-dev-machine.yaml. This creates your job on the cluster.

4. Retrieve the name of the pod created to run your job using kubectl get pods --namespace <NAMESPACE>. This will be the name you provided for your job above, plus some random characters.

5. Get a shell inside the container using kubectl exec -it <PODNAME> --container dev-environment -- /bin/bash

6. When you are done, don't forget to kill your job using kubectl delete -f /path/to/kubernetes-dev-machine.yaml
