Cloud Document AI API: Service to parse structured information from unstructured or semi-structured documents using state-of-the-art Google AI such as natural language, computer vision, translation, and AutoML.

• Client Library Documentation
• Product Documentation

In order to use this library, you first need to go through the following steps:

1. Select or create a Cloud Platform project.
2. Enable billing for your project.
3. Enable the Cloud Document AI API.
4. Setup Authentication.

Install this library in a virtualenv using pip. virtualenv is a tool to create isolated Python environments. The basic problem it addresses is one of dependencies and versions, and indirectly permissions.

With virtualenv, it's possible to install this library without needing system install permissions, and without clashing with the installed system dependencies.

pip install virtualenv
virtualenv <your-env>
source <your-env>/bin/activate
<your-env>/bin/pip install google-cloud-documentai

pip install virtualenv
virtualenv <your-env>
<your-env>\Scripts\activate
<your-env>\Scripts\pip.exe install google-cloud-documentai

1. Install pyenv for your platform

2. Install the latest versions of python version 3.6, 3.7, 3.8, and 3.9 via pyenv.

   pyenv install 3.9.${3_9_LATEST_PATCH}
   pyenv install 3.8.${3_8_LATEST_PATCH}
   pyenv install 3.7.${3_7_LATEST_PATCH}
   pyenv install 3.6.${3_6_LATEST_PATCH}

   For example:

   pyenv install 3.9.7
   pyenv install 3.8.12
   pyenv install 3.7.11
   pyenv install 3.6.14

1. Change directories to the root of this repo

2. Create a 3.8 Python virtual enviornment via pyenv:

   pyenv virtualenv 3.8.${3_8_LATEST_PATCH} docai-venv

   For example:

   pyenv virtualenv 3.8.12 docai-venv

3. Acitivate the virtual enviornment and use Python versions 2.7, 3.6, 3.7, and 3.9:

   pyenv local docai-venv \
      3.9.${3_9_LATEST_PATCH} \
      3.8.${3_8_LATEST_PATCH} \
      3.7.${3_7_LATEST_PATCH} \
      3.6.${3_6_LATEST_PATCH}

   For example:

   pyenv local docai-venv 3.9.7 3.8.12 3.7.11 3.6.14

4. Install the required library dependencies and test dependencies in the virtual enviornment:

   pip install google-cloud-documentai nox

Run all tests:

1. Change directory to the root of the repo

2. Run Nox:

   nox

Run system tests:

nox -s system

Run unit tests:

nox -s unit

Run tests for a specific version of Python:

nox -s py-3.8

Run documentation tests:

nox -s docs
