There was a problem hiding this comment.
I used the instructions to install the dependencies:
conda env create -f environment.yaml
conda activate ldm
But I get the following error when I try to run python scripts/txt2img.py --prompt "a photograph of an astronaut riding a horse"
[Traceback (most recent call last):
File "scripts/txt2img.py", line 20, in <module>
from ldm.models.diffusion.dpm_solver import DPMSolverSampler
File "/home/opc/stable-diffusion/ldm/models/diffusion/dpm_solver/__init__.py", line 1, in <module>
from .sampler import DPMSolverSampler
File "/home/opc/stable-diffusion/ldm/models/diffusion/dpm_solver/sampler.py", line 5, in <module>
from .solver import NoiseScheduleVP, model_wrapper, DPM_Solver
ModuleNotFoundError: No module named 'ldm.models.diffusion.dpm_solver.solver'
]
Any ideas as to what is happening?

DPM-Solver (https://github.com/LuChengTHU/dpm-solver) is much faster than PLMS and DDIM, which can generate almost converged samples in only 20-25 steps.
Example images of the difference between DDIM, PLMS, and DPM-Solver can be found in: https://github.com/LuChengTHU/dpm-solver/tree/main/example_v2/stable-diffusion
