Install Vertex AI client libraries

Vertex AI client libraries in Google Distributed Cloud (GDC) air-gapped appliance let you programmatically access Optical Character Recognition (OCR), Speech-to-Text, Vertex AI Translation, and Vertex AI Platform APIs from supported languages without writing raw server requests. Extract and install a client library directly from its tar file for your CentOS or Ubuntu operating system.

Vertex AI client libraries

Vertex AI offers different versions of client libraries for CentOS and Ubuntu operating systems.

The naming conventions of Vertex AI client libraries in the tar file are based on the operating system, the service name, and the version. The filenames adhere to the following format:

OS-google-cloud-SERVICE-VERSION.tar.gz

Replace the following:

• OS: the name of the operating system where you want to install the client library. Allowed values are centos and ubuntu.

• SERVICE: the name of the Vertex AI service from which you want to download the client library. The following are the allowed values:

  • aiplatform: the Vertex AI Platform client library.
  • speech: the Speech-to-Text client library.
  • translate: the Vertex AI Translation client library.
  • vision: the OCR client library.

• VERSION: the version number of the client library, such as 3.8.0.

The following table contains the Vertex AI client libraries that GDC air-gapped appliance supports:

Before you begin

Before downloading the tar file and extracting client libraries, follow these steps:

1. Set up a project for Vertex AI.

2. Authenticate with gdcloud CLI:

   gdcloud auth login
   

   For more information about how to authenticate with your configured identity provider, see the gdcloud CLI authentication.

3. Assign the Cloud AI Viewer (cloud-ai-viewer) role to a service account. The service account requires this role to access the Vertex AI services.

4. Verify that you have installed Python version 3.7.

Install a client library

After completing the prerequisites, follow these steps to download the tar file, and use the tar file to install a client library:

1. Download the client library you want to install:

   wget https://GDC_URL/.well-known/static/client-libraries/CLIENT_LIBRARY
   

   Replace the following:

   • GDC_URL: the URL of your organization in GDC.
   • CLIENT_LIBRARY: the filename of the client library you want to download.

2. Extract the library file:

   tar -zxf CLIENT_LIBRARY
   

3. Install the client library in GDC air-gapped appliance:

   pip install -r FOLDER_NAME/requirements.txt --no-index --find-links FOLDER_NAME
   

   Replace FOLDER_NAME with the path to the local directory where you downloaded the library file.

4. Import the client library using a Python script. The following example shows a code snippet of a Python script that imports the Vertex AI Translation client library to illustrate what importing libraries looks like:

   from google.cloud import translate
   translate_client = translate.Client(
    client_options={"API_ENDPOINT": "https://foo-translation.googleapis.com"})
   result
   = translate_client.translate(text, target_language="ru")
   
   [...]
   

   This code sample is not complete. To make a Vertex AI Translation request, learn about translation features.

5. Save the Python script with a name, such as translation-service.py.

6. Run the Python script:

   python SCRIPT_NAME
   

   Replace SCRIPT_NAME with the name you gave to your Python script, such as translation-service.py.
