UMA wont display my player

I'm using the UMA to make a custom player for my game

I typed this code

     void GenerateUMA()
     {
         // Create a new game object and add UMA componenets to it
         GameObject GO = new GameObject("MyUMA");
         umaDynamicAvatar = GO.AddComponent<UMADynamicAvatar>();
 
         // Initialise Avatar and grab a reference to it's data component
         umaDynamicAvatar.Initialize();
         umaData = umaDynamicAvatar.umaData;
         umaData.OnCharacterCreated += CharacterCreatedCallback;
 
         // Attach our generator
         umaDynamicAvatar.umaGenerator = generator;
         umaData.umaGenerator = generator;
 
         // Set up slot Array
         umaData.umaRecipe.slotDataList = new SlotData[numberOfSlots];
 
         // Set up our Morph references
         umaDna = new UMADnaHumanoid();
         umaTutorialDNA = new UMADnaTutorial();
         umaData.umaRecipe.AddDna(umaDna);
         umaData.umaRecipe.AddDna(umaTutorialDNA);
 
 
         // >>> This is where the fun will happen <<<
 
 
             CreateFemale();
 
 
         umaDynamicAvatar.animationController = animController;
 
         // Generate our UMA
         umaDynamicAvatar.UpdateNewRace();
 
         GO.transform.parent = this.gameObject.transform;
         GO.transform.localPosition = Vector3.zero;
         GO.transform.localRotation = Quaternion.identity;
 
     }
 
 void CreateFemale()
     {
         // Grab a reference to our recipe
         var umaRecipe = umaDynamicAvatar.umaData.umaRecipe;
         umaRecipe.SetRace(raceLibrary.GetRace("HumanFemale"));
 
         umaData.umaRecipe.slotDataList[0] = slotLibraray.InstantiateSlot("FemaleEyes");
         umaData.umaRecipe.slotDataList[0].AddOverlay(overlayLibrary.InstantiateOverlay("EyeOverlay"));
 
         umaData.umaRecipe.slotDataList[1] = slotLibraray.InstantiateSlot("FemaleInnerMouth");
         umaData.umaRecipe.slotDataList[1].AddOverlay(overlayLibrary.InstantiateOverlay("InnerMouth"));
 
         umaData.umaRecipe.slotDataList[2] = slotLibraray.InstantiateSlot("FemaleFace");
         umaData.umaRecipe.slotDataList[2].AddOverlay(overlayLibrary.InstantiateOverlay("FemaleHead01"));
 
         umaData.umaRecipe.slotDataList[3] = slotLibraray.InstantiateSlot("FemaleTorso");
         umaData.umaRecipe.slotDataList[3].AddOverlay(overlayLibrary.InstantiateOverlay("FemaleBody02"));
 
         umaData.umaRecipe.slotDataList[4] = slotLibraray.InstantiateSlot("FemaleHands");
         umaData.umaRecipe.slotDataList[4].SetOverlayList(umaData.umaRecipe.slotDataList[3].GetOverlayList());
 
         umaData.umaRecipe.slotDataList[5] = slotLibraray.InstantiateSlot("FemaleLegs");
         umaData.umaRecipe.slotDataList[5].SetOverlayList(umaData.umaRecipe.slotDataList[3].GetOverlayList());
 
         umaData.umaRecipe.slotDataList[6] = slotLibraray.InstantiateSlot("FemaleFeet");
         umaData.umaRecipe.slotDataList[6].SetOverlayList(umaData.umaRecipe.slotDataList[3].GetOverlayList());
 
         umaData.umaRecipe.slotDataList[3].AddOverlay(overlayLibrary.InstantiateOverlay("FemaleUnderwear01"));
 
         umaData.umaRecipe.slotDataList[2].AddOverlay(overlayLibrary.InstantiateOverlay("FemaleEyebrow01", Color.black));
 
         SetSlot(3, "AL_FemaleTShirt01_Slot");
         AddOverlay(3, "AL_FemaleTShirt01");
         SetSlot(5, "AL_FemaleShortSkirt01_Slot");
         AddOverlay(5, "AL_FemaleShortSkirt01");
         SetSlot(6, "AL_FemaleSneakers01_Slot");
         AddOverlay(6, "AL_FemaleSneakers01");
     }
     void Update()
     {
         if (bodyMass != umaDna.upperMuscle)
         {
             SetBodyMass(bodyMass);
             umaData.isShapeDirty = true;
             umaData.Dirty();
         }
 
         if (happy != expressionPlayer.midBrowUp_Down)
         {
             expressionPlayer.midBrowUp_Down = happy;
             expressionPlayer.leftMouthSmile_Frown = happy;
             expressionPlayer.rightMouthSmile_Frown = happy;
         }
 
 
 
         if (hairState && !lastHairState)
         {
             lastHairState = hairState;
             SetSlot(7, "FemaleLongHair01");
             AddOverlay(7, "FemaleLongHair01", hairColor);
             umaData.isMeshDirty = true;
             umaData.isTextureDirty = true;
             umaData.isShapeDirty = true;
             umaData.Dirty();
         }
         if (!hairState && lastHairState)
         {
             lastHairState = hairState;
             RemoveSlot(7);
             umaData.isMeshDirty = true;
             umaData.isTextureDirty = true;
             umaData.isShapeDirty = true;
             umaData.Dirty();
         }
 
         if (upperAtireColor != lastUpperAtireColor )
         {
             lastUpperAtireColor = upperAtireColor;
             ColorOverlay(3, "AL_FemaleTShirt01", upperAtireColor);
             umaData.isTextureDirty = true;
             umaData.Dirty();
         }
 
         if (lowerAtireColor != lastLowerAtireColor)
         {
             lastLowerAtireColor = lowerAtireColor;
             ColorOverlay(5, "AL_FemaleShortSkirt01", lowerAtireColor);
             umaData.isTextureDirty = true;
             umaData.Dirty();
         }
 
         if (shoeColor != lastShoeColor)
         {
             lastShoeColor = shoeColor;
             ColorOverlay(6, "AL_FemaleSneakers01", shoeColor);
             umaData.isTextureDirty = true;
             umaData.Dirty();
         }
 
         if (save)
         {
             save = false;
             SaveAsset();
         }
         if (load)
         {
             load = false;
             LoadAsset();
         }
 
     }

But it didn't show the player, how can I fix this?
