      Hint: you may nd it easier to create a Numpy array representing the structure rst, then turn that Numpy array into a TensorFlow constant. Second hint: as a sanity check, try printing your tensor. You should see a series of 4-by-3 matrices, as though you were looking at one horizontal slice of the tensor at a time, working your way from top to ...

      and NumPy dtypes match down the line. However, tf.string does not have an exact match in NumPy due to the way NumPy handles strings. TensorFlow can still import string arrays from NumPy perfectly fine -- just don’t specify a dtype in NumPy! Note 2 : Both TensorFlow and NumPy are n-d array libraries. NumPy supports ndarray, but
