Starting `invoke.py` with --no-xformers will disable memory-efficient-attention support if xformers is installed. --xformers will enable support, but this is already the default.

ldm.invoke.globals defines a small number of global variables that would
|
|
otherwise have to be passed through long and complex call chains.
|
|
|
|
It defines a Namespace object named "Globals" that contains
|
|
the attributes:
|
|
|
|
- root - the root directory under which "models" and "outputs" can be found
|
|
- initfile - path to the initialization file
|
|
- try_patchmatch - option to globally disable loading of 'patchmatch' module
|
|
- always_use_cpu - force use of CPU even if GPU is available
|
