How Do I Merge Two Datasets in ModelArts?

Datasets cannot be merged directly.

However, you can perform the following operations to merge the data of two datasets into a new dataset.

For example, to merge datasets A and B, do the following:

1. Publish datasets A and B.
2. Obtain the manifest files of the two datasets from the OBS path set for Output Dataset Path.
3. Create an empty dataset C and select an empty OBS folder for Input Dataset Path.
4. Import the manifest files of datasets A and B to dataset C.

   After the import is complete, data in datasets A and B is merged into dataset C. Publish dataset C so it can be used.
