This is because you don't have the packages installed. Install whatever missing package inside the forge. Go to the forge system/python directory in a terminal (cmd or powershell), install the missing packages as follows. PS D:\webui_forge_cu121_torch21\system\python> .\python.exe -m pip install launch
