How to access tensor_content values ​​in TensorProto in TensorFlow?

How How to access values ​​in protos in TensorFlow? but not suitable for this case.

I can see the attribute bytes tensor_content

in TensorProto . I am trying to get information about nodes via:

for node in tf.get_default_graph().as_graph_def().node: node.attr['value'].tensor.tensor_content # decode these bytes

For information, the print node looks something like this:

name: "conv2d/convolution/Shape"
op: "Const"
device: "/device:GPU:0"
attr {
  key: "dtype"
  value {
    type: DT_INT32
  }
}
attr {
  key: "value"
  value {
    tensor {
      dtype: DT_INT32
      tensor_shape {
        dim {
          size: 4
        }
      }
      tensor_content: "\003\000\000\000\003\000\000\000\001\000\000\000 \000\000\000"
    }
  }
}
