无法使用Go正确获取

I am a new user to go and I am trying this command.

go get github.com/tensorflow/tensorflow/tensorflow/contrib/go

And I am getting this error

package github.com/tensorflow/tensorflow/tensorflow/contrib/go
    imports github.com/tensorflow/tensorflow/tensorflow/contrib/go
    imports github.com/tensorflow/tensorflow/tensorflow/contrib/go: cannot find package "github.com/tensorflow/tensorflow/tensorflow/contrib/go" in any of:
    /usr/lib/go/src/pkg/github.com/tensorflow/tensorflow/tensorflow/contrib/go (from $GOROOT)
    /home/arafat/go/src/github.com/tensorflow/tensorflow/tensorflow/contrib/go (from $GOPATH)

I know this seems to be a trivial issue but I am stuck at it.

If the code to compile and install is not in the master branch (checked out by default by the go get), but only in the go branch of that repo, try and:

cd $GOPATH/github.com/tensorflow/tensorflow
git checkout go

Then try again the compilation.
