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"))
