Question

I Run stable diffusion,It`s wrong RuntimeError: "LayerNormKernelImpl" not implemented for 'Half',help me,how i do?

I have no idea for it

Answer 1

'LayerNorm' is one of the layers in the Model. Looks like you're trying to load the diffusion model in float16(Half) format on CPU which is not supported. For float16 format, GPU needs to be used. For CPU run the model in float32 format.

Answer 2

I solved it in the following way, modify the launch.py file in the following way, add the following line of code:

commandline_args = os.environ.get('COMMANDLINE_ARGS', "--skip-torch-cuda-test --no-half")
