Swift for TensorFlow`错误：无法查找符号：为TensorFlow.Tensor输入元数据访问器

Question

以下行 -

import TensorFlow
let matrix = Tensor<Float>([[1, 2], [3, 4]])

在macOS playground中执行产生错误 -

error: Couldn't lookup symbols:
  type metadata accessor for TensorFlow.Tensor

Xcode 10.2，Swift for TensorFlow Release 0.2,2019-03-02

关于如何解决这个问题的任何想法？

附：使用0.3,2019-04-23工具链时问题仍然存在。
