Mac M1 ComfyUI 中 AnyText插件安装问题汇总？

Q1：NameError: name ‘PreTrainedTokenizer’ is not defined ?

该项目最近更新日期为2024年12月，该时间段的transformers 版本由PyPI 上的 transformers 页面 可知为4.47.1.

A1: transformers 版本不满足要求，必须降级transformors ？

（1）查看 transformers 版本

pip index versions transformers 

发现是最新版4.48.2，降级到4.46.2

pip install transformers==4.46.2

Q2：“ComfyUI/custom_nodes/ComfyUI_Anytext/Image_Generation_AnyText/Site_Packages/AnyTextControlDiffusion/ldm/modules/encoders/modules.py” AssertionError: Torch not compiled with CUDA enabled". ?

A2: 将modules.py文件里下面这行代码：

tokens = tokens.to(self.device)

修改为如下内容：

self.device = torch.device("mps" if torch.backends.mps.is_available() else "cpu")
tokens = tokens.to(self.device)

Q3:‘ComfyUI_Anytext/Image_Generation_AnyText/Site_Packages/AnyTextControlDiffusion/cldm/ddim_hacked.py’ AssertionError: Torch not compiled with CUDA enabled？

A3:

在 ddim_hacked.py 文件中，将 register_buffer 方法里这行代码

attr = attr.to(torch.device("cuda"))

修改为

if torch.backends.mps.is_available():attr = attr.to(torch.device("mps"))
else:attr = attr.to(torch.device("cpu"))

Q4: ComfyUI/custom_nodes/ComfyUI_Anytext/Image_Generation_AnyText/Site_Packages/AnyTextControlDiffusion/cldm/ddim_hacked.py", line 22, in register_buffer attr = attr.to(torch.device(“mps”)) TypeError: Cannot convert a MPS Tensor to float64 dtype as the MPS framework doesn’t support float64. Please use float32 instead?

A4:

在 ddim_hacked.py 文件中，将 register_buffer 方法里这行代码

if torch.backends.mps.is_available():attr = attr.to(torch.device("mps"))
else:attr = attr.to(torch.device("cpu"))

修改为:

if attr.dtype == torch.float64:attr = attr.to(torch.float32)
if torch.backends.mps.is_available():attr = attr.to(torch.device("mps"))
else:attr = attr.to(torch.device("cpu"))
