Common Errors
ModuleNotFoundError7 reportsThis error typically occurs in comfyui. Check the example issues for common solutions.
OutOfMemoryError6 reportsThis error typically occurs in comfyui. Check the example issues for common solutions.
FileNotFoundError4 reportsThis error typically occurs in comfyui. Check the example issues for common solutions.
NotImplementedError4 reportsNotImplementedError 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).
ConnectionResetError3 reportsConnectionResetError in ComfyUI often arises from exceeding your system's resources (VRAM or RAM) or unstable network connections when dealing with large files/models. Try reducing the batch size or image resolution to lower VRAM usage, and ensure a stable internet connection when downloading/using online resources. Consider enabling CPU offloading or optimized options if available in custom nodes.
CalledProcessError3 reportsCalledProcessError in ComfyUI usually stems from errors during external program execution, often due to incorrect file paths, missing dependencies, or command-line argument issues within custom nodes. To fix it, carefully examine the specific error message's stderr output, then ensure the external program is correctly installed and its path is set up properly in the executing custom node's code, and that all command line arguments passed to the external program are valid.
