Solve the following python programming problem given the following code:
@ SkipTest 
def test_dim_size(self) : 
    def get_dim_size(expr) : 
        producer = expr.children () [0].input.input 
        return producer.hyper_cube_dimensions 
def get_work_load(expr, dim_sizes) : 
        children = expr.children () 
        children = [c.input for c in children] 
        child_schemes = [c.scheme () for c in children] 
        conditions = myrialang.convert_nary_conditions (expr.conditions, child_schemes) 
        HSClass = myrialang.HCShuffleBeforeNaryJoin 
        r_index = HSClass.reversed_index (child_schemes, conditions) 
        child_sizes = [len (cs) for cs in child_schemes] 
        return HSClass.workload (dim_sizes, child_sizes, r_index) 
triangular_join = testNaryJoin.get_phys_plan_root ('A(x,y,z):-R(x,y),S(y,z),T(z,x)', 64) 
    self.assertEqual (get_dim_size (triangular_join), (4, 4, 4)) 
    rect_join = testNaryJoin.get_phys_plan_root ('A(x,y,z):-R(x,y),S(y,z),T(z,p), N(p,x)', 256) 
    self.assertEqual (get_work_load (get_work_load, [4, 4, 4, 4]), get_work_load (rect_join, get_dim_size (rect_join))) 

    
    

    Fix the buggy line: self.assertEqual (get_work_load (get_work_load, [4, 4, 4, 4]), get_work_load (rect_join, get_dim_size (rect_join)))
assistant
#Here is Python code to fix the buggy line: self.

self.assertEqual (get_work_load (rect_join, [4, 4, 4, 4]), get_work_load (rect_join, get_dim_size (rect_join)))
