Current behavior?

The parameter x is expected to be two-dimensional, and an error will occur when x is one-dimensional

Standalone code to reproduce the issue

import tensorflow as tf

use_peephole = False
x = tf.constant(0, shape=[17], dtype=tf.float32)
cs_prev = tf.constant(0.837607, shape=[28,29], dtype=tf.float32)
h_prev = tf.constant(0.837607, shape=[28,29], dtype=tf.float32)

wci = tf.constant(0.837607, shape=[28,29], dtype=tf.float32)
wcf = tf.constant(0.837607, shape=[28,29], dtype=tf.float32)

Hi @LongZE666 ,

Thanks for reporting. I have reproduced the reported behaviour and attached gist here.

The checkfail is happening with 1D input to the argument x .

Attaching also snapshot of same below.
