Encodes each input in value according to a distribution selected by index.
tfc.ops.entropy_encode_index(
handle, index, value, name=None
)
In general, entropy encoders in handle reference multiple distributions.
index selects which distribution is used to encode value. For example, if
value is a 3-D array, then value(i,j,k) is encoded using the
index(i,j,k)-th distribution. index and value must have the same shape.
handle controls the number of coding streams. Suppose that value and index
have the shape [2, 3, 4] and that handle has shape [2]. Then the first
slice [0, :, :] of shape [3, 4] is encoded into handle[0] and the second
slice [1, :, :] is encoded into handle[1]. If handle has shape [], then
there is only one handle, and the entire input is encoded into a single stream.
Values must be in the provided ranges specified when the input handle was
originally created, unless overflow functionality was enabled. The handle may
be produced by the CreateRangeEncoder op, or may be passed through from a
different EntropyEncodeChannel/EntropyEncodeIndex op.
Because the op modifies handle, the corresponding input edge to the op nodes
of this type should not have other consumers in the graph.
