How to concatenate two tensors horizontally in TensorFlow?

Question

I have 2 tensors of shape (100, 4) and (100, 2). I would like to perform a concatenation operation, in TensorFlow, similar to np.hstack,

Answer 1

I tried the above code, I got some error. The following code runs fine with tf 1.15 version:

x = tf.constant( [[1, 2,4],[7,8,12]])

y = tf.constant([[88],[99]])

res=tf.concat([x, y],1)
