Minimal steps to reproduce

follow the tutorial, configure the workspace and try to execute deploy-onnx-yolo-model.ipynb, when creating the docker image it returns an error.

Any log messages given by the failure

Creating image
Running......
Failed
ERROR - Image creation polling reached non-successful terminal state, current state: Failed
Error response from server:
StatusCode: 400
Message: Docker image build failed.

in the build.log it seems that the docker is ok and it is trying as last step to download the model to save it in the /var/azureml-app/azureml-models/tiny_yolov2/2 folder, and it gives an error related to the tar file
