Does go-tflite supports string tensors?

[juancresc]

I only see SetFloat32s function. We have a converted model that accepts floats, strings and stringlists as input.

	interpreter.AllocateTensors()
	input := interpreter.GetInputTensor(0)
	input.SetFloat32s([]float32{0.5})

Probably, you might mean DynamicBuffer.

@mattn are there any examples on how to create tensors with string or lists of string ? thanks!

See _example/smartreply.

@mattn do you think is this related to the fact I'm using macOS arm64?

	tfliteModel := tflite.NewModelFromFile("model.tflite")
	interpreter := tflite.NewInterpreter(tfliteModel, nil)

	var dbuf = new(tflite.DynamicBuffer)
	dbuf.AddString("demo")
	dbuf.WriteToTensorAsVector(interpreter.GetInputTensor(37))

Can you provide simplest code to do same in Python ?
