TypeError: unsupported operand type(s) for |=: 'dict' and 'dict'

Lines 241 to 242 in e2c76ef

    
           state |= {op:oe.subs(state) for op,oe in mod.out_exprs.items()} 
        
           state |= {pi:state[po] for po,pi in connectivity if po in state}

Ran into this when running py3 new_arch.py, trying to solve it

Not compatible with Python 3.9 and PEP 584

Solved, will include in control_solver branch pending a pull request

  for model in ready_models:
      for output_key, output_expression in model.out_exprs.items():
          state.update({
              output_key: output_expression.subs(state)
          })
      for output_port, input_port in connectivity:
          if output_port in state:
              state.update({
                  input_port: state[output_port]
              })
  model_set -= ready_models

Now got:
