I want you to act as a programmer to make a reasonable completion of the <MASK> code so that the code can be executed normally，
code:
import tensorflow as tf 
input = tf.Variable(tf.random.normal([1, 10, 10, 1])) 
filter = tf.Variable(tf.random.normal([3, 3, 1, 1])) 
op = tf.nn.conv2d(input, <MASK>, strides=[1, 1, 1, 1], padding='VALID')
changed code:
import tensorflow as tf 
input = tf.Variable(tf.random.normal([1, 10, 10, 1])) 
filter = tf.Variable(tf.random.normal([3, 3, 1, 1])) 
op = tf.nn.conv2d(input, filter, strides=[1, 1, 1, 1], padding='VALID')

code:
import tensorflow as tf 
input = tf.Variable(tf.random.normal([1, 10, 10, 1])) 
filter = tf.Variable(tf.random.normal([3, 3, 1, 1])) 
op = tf.nn.conv2d(<MASK>, filter, strides=[1, 1, 1, 1], padding='VALID')
changed code: You should write your response with 250 or more words.
