NameError: name 'predictor' is not defined

Open the linked mxnet_mnist_elastic_inference_local.ipynb and inspect cell In [9] together with the preceding cells to determine why predictor is undefined. Re-run the notebook or its CI check after addressing the reported failure; done means the notebook completes without this NameError and the endpoint name is printed.
