我是一个新用户，正在尝试此命令。

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

我得到这个错误

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)

我知道这似乎是一个琐碎的问题，但我坚持下去。
