Open advanced_functionality/fairseq_translation/fairseq_sagemaker_pretrained_en2fr.ipynb and inspect cell In [4], where create_container.sh is run. Reproduce the notebook CI failure, then trace the nonzero exit from ./create_container.sh; done means the notebook completes that cell successfully in CI.
