CommandException is occurred when i'm on training cloudml

I faced the problem that CommandException is occurred when i'm on training [CloudML samples](https://github.com/GoogleCloudPlatform/cloudml-samples).

when I tried on terminal
`gsutil cp gs://cloudml-public/census/data/* data/`
`zsh: no matches found: gs://cloudml-public/census/data/*`

I saw [this solution](https://stackoverflow.com/questions/39075182/gsutil-returning-no-matches-found), and tried following.

`sudo gsutil 'cp gs://cloudml-public/census/data/* data/'`
`CommandException: Invalid command "cp gs://cloudml-public/census/data/* data/".`

I'm using

- OS X(Sierra)
- Terminal(default)
- Zsh (a little customized)

please tell me this solution.
