The CI used to failed due to the test cases trying to download the MNIST dataset from a url which is no longer accessible.
The ssd uses API of mindspore.MindDataset.project. It is defined as mindspore.dataset.Dataset.project(columns) in the most recent mindspore version. The previous PR wrongly used the parameter name as "output_columns".
