TypeError: a bytes-like object is required

[ZeroX]

Ah ok, I think I have not understood the purpose of the program. I thought it took elements from the source code to convert the PIC file format into human readable, but in the below structure:

Pickup Locations (*.PIC):
 
Magic Number: uint32
Pic Version Number: uint32
 
NumRegenPoints: int16
{
    gen_type: int16
      regen_type: int16
       gen_delay: float
       life_span: float
             pos: VECTOR
             {
               x: float
               y: float
               z: float
             }
           group: int16
            Type: int16
      TriggerMod: int16
}

From what you have said even if it executed properly once it is in the YAML format it will still be mostly useless in relation to the above structure?
