forge_space_photo_maker_v2, bf16 is only supported on A100+ GPUs

fa2F@v2.6.3-24-gbdf733b is not supported because: requires device with capability > (8, 0) but your GPU has capability (7, 5) (too old) bf16 is only supported on A100+ GPUs cutlassF-pt is not supported because: bf16 is only supported on A100+ GPUs

我在运行 PhotoMaker V2 时，报错 GPU 不支持，然后我改了文件 webui\extensions-builtin\forge_space_photo_maker_v2\forge_app.py 第 40 行 :

if torch.cuda.is_available() and torch.cuda.is_bf16_supported():
    torch_dtype = torch.bfloat16
else:
    torch_dtype = torch.float16

改为

if torch.cuda.is_available() and torch.cuda.is_bf16_supported():
    torch_dtype = torch.float16
else:
    torch_dtype = torch.float16

就可以了，我不知道哪里的问题，竟然蒙对了，期望敏神修复它，提一个 Issue，希望对遇到相同报错的朋友有用
