Migrating the Data of MLS to ModelArts
HUAWEI CLOUD plans to terminate Machine Learning Service (MLS). You are advised to use related functions of MLS in ML Studio of ModelArts. To ensure the normal running of service data, you are advised to perform the following operations to migrate data.
Migrating Data
The MLS pro edition supports data to be stored in HDFS, and the MLS standard edition supports data to be stored in datasets and OBS. ML Studio reads data from and writes data to OBS. Therefore, you need to manually migrate MLS data to OBS.
For details about how to create an OBS bucket and folder, see Creating a Bucket and Creating a Folder.
For details about how to upload files to OBS, see Uploading a File.
To facilitate service migration to ModelArts, you are advised to create the same OBS buckets and folders as those of the data stored in MLS.
Create buckets and folders in OBS, and upload the data and models of MLS to the new OBS buckets.
Migrating Workflows
The workflow capabilities of ML Studio and MLS are the same. The supported data source is changed. As a result, the operators for reading and writing data are changed. You need to orchestrate the operators in the workflow again. For details about operator changes, see Table 1 and Table 2. Read Model From OBS and Save Model to OBS only support the models in inner format.
