stop gradients flowing in a joint loss

I have an input tensor data = tf.placeholder(tf.int32, [None]) which will be embedded by embedding_matrix = tf.get_variable(“embedding_matrix”, [5,3], tf.float32, initializer=tf.random_normal_initializer()) input_vectors = tf.nn.embedding_lookup(params=embedding_matrix, ids=data) I perform a linear transformation on the input vector using output1_weights to get network_output1 output1_weights = tf.get_variable(“output1”, [3,4], tf.float32, initializer=tf.random_normal_initializer()) network_output1 = tf.matmul(input_vectors, output1_weights) The loss will be very standard stuff…
