tf.compat.v1.raw_ops.BlockLSTM

tf.raw_ops.BlockLSTM(
    seq_len_max, x, cs_prev, h_prev, w, wci, wcf, wco, b, forget_bias=1,
    cell_clip=3, use_peephole=False, name=None
)

This is equivalent to applying LSTMBlockCell in a loop, like so:

for x1 in unpack(x):
  i1, cs1, f1, o1, ci1, co1, h1 = LSTMBlock(
    x1, cs_prev, h_prev, w, wci, wcf, wco, b)
  cs_prev = cs1
  h_prev = h1
  i.append(i1)
  cs.append(cs1)
  f.append(f1)
  o.append(o1)
  ci.append(ci1)
  co.append(co1)
  h.append(h1)
return pack(i), pack(cs), pack(f), pack(o), pack(ci), pack(ch), pack(h)

Args
`seq_len_max`	A `Tensor` of type `int64`. Maximum time length actually used by this input. Outputs are padded with zeros beyond this length.
`x`	A `Tensor`. Must be one of the following types: `half`, `float32`. The sequence input to the LSTM, shape (timelen, batch_size, num_inputs).
`cs_prev`	A `Tensor`. Must have the same type as `x`. Value of the initial cell state.
`h_prev`	A `Tensor`. Must have the same type as `x`. Initial output of cell (to be used for peephole).
`w`	A `Tensor`. Must have the same type as `x`. The weight matrix.
`wci`	A `Tensor`. Must have the same type as `x`. The weight matrix for input gate peephole connection.
`wcf`	A `Tensor`. Must have the same type as `x`. The weight matrix for forget gate peephole connection.
`wco`	A `Tensor`. Must have the same type as `x`. The weight matrix for output gate peephole connection.
`b`	A `Tensor`. Must have the same type as `x`. The bias vector.
`forget_bias`	An optional `float`. Defaults to `1`. The forget gate bias.
`cell_clip`	An optional `float`. Defaults to `3`. Value to clip the 'cs' value to.
`use_peephole`	An optional `bool`. Defaults to `False`. Whether to use peephole weights.
`name`	A name for the operation (optional).

Returns
A tuple of `Tensor` objects (i, cs, f, o, ci, co, h).
`i`	A `Tensor`. Has the same type as `x`.
`cs`	A `Tensor`. Has the same type as `x`.
`f`	A `Tensor`. Has the same type as `x`.
`o`	A `Tensor`. Has the same type as `x`.
`ci`	A `Tensor`. Has the same type as `x`.
`co`	A `Tensor`. Has the same type as `x`.
`h`	A `Tensor`. Has the same type as `x`.
