We will disable label_text_test.py::test_label_text and manage_dataset_test.py::test_list_dataset in datalabeling directory.

Failed build

It seems like

• the dataset is considered empty for label_text_test.py::test_label_text.
• the test backend is throwing DeadlineExceeded for manage_dataset_test.py::test_list_dataset.

This bug is to debug them and re-enable them if possible.
