## Installation

AllenNLP requires Python 3.6.1 or later. The preferred way to install AllenNLP is via `pip`. Just run `pip install allennlp` in your Python environment and you're good to go!

If you need pointers on setting up an appropriate Python environment or would like to install AllenNLP using a different method, see below.

Windows is currently not officially supported, although we try to fix issues when they are easily addressed.

### Installing via pip

#### Setting up a virtual environment

[Conda]( can be used set up a virtual environment with the
version of Python required for AllenNLP. If you already have a Python 3.6 or 3.7
environment you want to use, you can skip to the 'installing via pip' section.

1. [Download and install Conda](

2. Create a Conda environment with Python 3.6

conda create -n allennlp python=3.6

3. Activate the Conda environment. You will need to activate the Conda environment in each terminal in which you want to use AllenNLP.

source activate allennlp

#### Installing the library and dependencies

Installing the library and dependencies is simple using `pip`.

pip install allennlp

That's it! You're now ready to build and train AllenNLP models.
AllenNLP installs a script when you install the python package, meaning you can run allennlp commands just by typing `allennlp` into a terminal.

You can now test your installation with `allennlp test-install`.

_`pip` currently installs Pytorch for CUDA 9 only (or no GPU). If you require an older version,
please visit and install the relevant pytorch binary._

### Installing using Docker

Docker provides a virtual machine with everything set up to run AllenNLP--
whether you will leverage a GPU or just run on a CPU. Docker provides more
isolation and consistency, and also makes it easy to distribute your
environment to a compute cluster.

Once you have [installed Docker](
just run the following command to get an environment that will run on either the cpu or gpu.

docker run -it -p 8000:8000 --rm allennlp/allennlp:v0.7.1

You can test the Docker environment with `docker run -it -p 8000:8000 --rm allennlp/allennlp:v0.7.1 test-install`.

### Installing from source

You can also install AllenNLP by cloning our git repository:

git clone

Create a Python 3.6 virtual environment, and install the necessary requirements by running:


Changing the flag to false if you don't want to be able to run
tests. Once the requirements have been installed, run:

pip install --editable .

To install the AllenNLP library in `editable` mode into your
environment. This will make `allennlp` available on your
system but it will use the sources from the local clone you
made of the source repository.

You can test your installation with `bin/allennlp test-install`.
The full development environment also requires the JVM and `perl`,
which must be installed separately. `./scripts/` will run
the full suite of tests used by our continuous build environment.

## Running AllenNLP

Once you've installed AllenNLP, you can run the command-line interface either
with the `allennlp` command (if you installed via `pip`) or `bin/allennlp` (if you installed via source).

$ allennlp
Run AllenNLP

optional arguments:
-h, --help show this help message and exit
--version show program's version number and exit


configure Generate configuration stubs.
train Train a model
evaluate Evaluate the specified model + dataset
predict Use a trained model to make predictions.
make-vocab Create a vocabulary
elmo Use a trained model to make predictions.
fine-tune Continue training a model on a new dataset
dry-run Create a vocabulary, compute dataset statistics and other
training utilities.
Run the unit tests.

## Docker images

AllenNLP releases Docker images to [Docker Hub]( for each release. For information on how to run these releases, see [Installing using Docker](#installing-using-docker).

### Building a Docker image

For various reasons you may need to create your own AllenNLP Docker image.
The same image can be used either with a CPU or a GPU.

First, you need to [install Docker](
Then run the following command
(it will take some time, as it completely builds the
environment needed to run AllenNLP.)

docker build -f Dockerfile.pip --tag allennlp/allennlp:latest .

You should now be able to see this image listed by running `docker images allennlp`.

allennlp/allennlp latest b66aee6cb593 5 minutes ago 2.38GB

### Running the Docker image

You can run the image with `docker run --rm -it allennlp/allennlp:latest`. The `--rm` flag cleans up the image on exit and the `-it` flags make the session interactive so you can use the bash shell the Docker image starts.

You can test your installation by running `allennlp test-install`.
