I was trying to run the beam Python-SDK example, but I had problem in reading the input.

This error is because your version of google-apitools is too old. You need v0.5.23 or newer to avoid this error.
Beam python has strict version requirements for dependencies. If you are running Beam 2.11, you need to be using google-apitools v0.5.26.
