How do you run tensorflow on colaboratory? - python-3.x

Question

I'm trying to use Google's Colaboratory. The first line of output was hopeful.
Using TensorFlow backend.
But then I got this error message.
ImportError: libcublas.so.9.0: cannot open shared object file: No such file or directory
That error apparently triggered another error. (Sorry for the long stack trace, but the error message itself suggested including it when asking for help.)
During handling of the above exception, another exception occurred:

Below that was a suggestion to consult https://www.tensorflow.org/install/install_sources#common_installation_problems.
But that page is about installing TensorFlow from source. I'm not trying to install from source. I just want a runnable version that I can call.
Any suggestions would be appreciated.
Thanks.
