Getting Started

This document describes how to call MoXing Framework APIs in ModelArts.

Logging In to ModelArts and Creating a Notebook Instance

  1. Log in to the ModelArts management console. In the left navigation pane, choose DevEnviron > Notebooks to switch to the Notebooks page.
  2. Click Create. On the Create Notebook page that is displayed, create a notebook instance by referring to Creating a Notebook Instance.
  3. After a notebook instance is created and is in the Running status, click the notebook instance name or click Open in the Operation column to go to the Jupyter development page.
  4. On the Files tab page, click New in the upper right corner and select the required AI engine to create a notebook file for encoding. In this example, you can create a TensorFlow file.

    After the file is created, the Jupyter page is displayed by default.

Calling mox.file.

Enter the following code to implement the following simple functions:

  1. Introduce MoXing Framework.
  2. Create the test01 folder in the existing modelarts-test08/moxing directory.
  3. Check whether the test01 folder exists. If the folder exists, the preceding operation is successful.

import moxing as mox

mox.file.make_dirs('obs://modelarts-test08/moxing/test01')
mox.file.exists('obs://modelarts-test08/moxing/test01')

Figure 3 shows the result. Note that each time you enter a line of code, click Run. You can also go to OBS Console and check whether the test01 folder has been created in the modelarts-test08/moxing directory. For more common MoXing operations, see Sample Code for Common Operations.
