Open training/distributed_training/tensorflow/data_parallel/maskrcnn/tensorflow2_smdataparallel_maskrcnn_demo.ipynb and start at In [12], where estimator.fit(inputs=data_channels, job_name=job_name) fails. Reproduce the CI run and inspect the filesystem input configuration. Done means the notebook completes CI without the FileSystemId validation error.
