Fix NotImplementedError

✅ Solution

NotImplementedError in ComfyUI usually arises when an operation or data type (like Float8_e4m3fn) is used that's not supported by the specific hardware backend (like MPS on Apple M1) or a custom node. To fix this, try updating ComfyUI and any custom nodes involved to their latest versions, as newer versions often add support for more data types and hardware; otherwise, try using a different sampler or model that is compatible with your hardware, or switch to a different execution device if possible (e.g., CUDA if available).
