										##initialized to one of the vectors from the available data points
										lowercase							=						[
										    tf.Variable(vectors[vector_indices[i]]		) for i in range(lowerCAmelCase__		)

										##values

										lowercase							=						[]
										for centroid in centroids:
															cent_assigns.append(tf.assign(lowerCAmelCase__ ,			lowerCAmelCase__		)		)

										##to 0 at first)
										lowercase							=						[tf.Variable(0		) for i in range(len(lowerCAmelCase__		)		)]
										##These nodes will assign an assignment Variable the appropriate
										##value
										lowercase							=						tf.placeholder('''int32'''		)
										lowercase							=						[]
										for assignment in assignments:
															cluster_assigns.append(tf.assign(lowerCAmelCase__ ,			lowerCAmelCase__		)		)

										# The placeholder for the input

										# dimension, i.e. the list of input vectors

										# iterations, instead of using a Stopping Criterion.

																				# Now assign the value to the appropriate state variable
																				sess.run(
																				    cluster_assigns[vector_n] ,			feed_dict={assignment_value: assignment}		)
