ImportError: Using low_cpu_mem_usage=True or a device_map requires Accelerate: `pip install 'accelerate>=0.26.0'

[pes1972]

Getting this error when trying to use the built in Photomaker V2. Any ideas how to fix. Installed latest accelerate but still same error.

accelerate was pinned to 0.21.0 in requirements_versions.txt, so you got auto-downgraded when you started Forge. I've bumped it to 0.31.0, to match the minimum version expected by diffusers.

Thank you :)

After your fix it goes a bit further when launching but now it crashes with this error:

File "C:\Forge\webui\extensions-builtin\forge_space_photo_maker_v2\huggingface_space_mirror\pipeline_t2i_adapter.py", line 222, in load_photomaker_adapter
File "C:\Forge\system\python\lib\site-packages\huggingface_hub\utils_validators.py", line 114, in _inner_fn
return fn(*args, **kwargs)
TypeError: _get_model_file() got an unexpected keyword argument 'resume_download'

[DenOfEquity]

This is a bug in the version of the original Huggingface Space that Forge targetted (past tense, since a few minutes). A diffusers update made that keyword argument defunct, the functionality now automatic.

Two options:

1. manual fix
   • open C:\Forge\webui\extensions-builtin\forge_space_photo_maker_v2\huggingface_space_mirror\pipeline_t2i_adapter.py in a text editor
   • find line 226: resume_download=resume_download,
   • delete that line, or comment it out by adding # at the start
2. auto (I've updated the HF Space revision that the Forge Space targets)
   • update Forge again
   • in Spaces tab, uninstall PhotoMaker V2
   • then install it

Everything working now, thanks again for your help :)
