Common Usage

This object is used to centrally manage input directories. The following is an example:

import modelarts.workflow as wf
storage = wf.data.InputStorage(name="storage_name", title="title_info", description="description_info") # Only name is mandatory.
input_data = wf.data.OBSPath(obs_path = storage.join("directory_path")) # Add a slash (/) after a directory, for example, storage.join("/input/data/").

When a workflow is running, if the root path of the storage object is /root/, the obtained path will be /root/directory_path.

This object is used to centrally manage output directories and ensure that multiple executions of the same workflow are output to different directories. The following is an example:

import modelarts.workflow as wf
storage = wf.data.OutputStorage(name="storage_name", title="title_info", description="description_info") # Only name is mandatory.
output_path = wf.data.OBSOutputConfig(obs_path = storage.join("directory_path")) # Only a directory can be created but not files.

When a workflow is running, if the root path of the storage object is set to /root/, the system will automatically create a relative directory and the obtained path will be /root/Execution ID/directory_path.
