Trying to convert Float8_e4m3fn to the MPS backend but it does not have support for that dtype.

[ZeeMenng]

换了各种weight_type都不行。

关掉fp8_fast_mode可以吗

[ZeeMenng]

不行，关掉后显示RuntimeError: unsupported scalarType

更新一下ComfyUI-CogVideoXWrapper试试

[ZeeMenng]

全都升级过了，一样的错误，试了各种办法不行，很奇怪。

我的是M1 Pro，Python我用3.12和3.11两个版本分别作了尝试，都不行。不知道哪个依赖包版本有问题，还是怎样的。

[wailovet]

目前看起来支持应该有些问题, 可以看 kijai/ComfyUI-CogVideoXWrapper#59
