RuntimeError: "addmm_impl_cpu_" not implemented for 'Half'

[WestbrookZero]

i don't have enough VRAM, when i change to use cpu device , there is an error:

WARNING: This decoder was trained on an old version of Dalle2. This may result in the model failing to load or it may lead to producing garbage results.
