example script doesn't work with pip install

[richardrl]

The pip package doesn't include any of these:

from diffusers.modeling_utils import unwrap_model
from diffusers.optimization import get_scheduler
from diffusers.utils import logging

so "train_unconditional.py" fails:

python3 train_unconditional.py --dataset="cifar10" --resolution=64 --output_path="cifar10-ddpm" --batch_size=16 --num_epochs=100 --gradient_accumulation_steps=1 --lr=1e-4 --warmup_steps=500 --mixed_precision=no

Traceback (most recent call last): File "train_unconditional.py", line 12, in <module> from diffusers.modeling_utils import unwrap_model ImportError: cannot import name 'unwrap_model'

Hey @richardrl,

We're still in the early stages of developping this library so especially the example code changes quite rapidly. To be able to run the example could you try to install the library from source?

git clone https://github.com/huggingface/diffusers.git
cd diffusers && pip install -e .

@patrickvonplaten had some trouble installing from source using poetry. Running poetry add git+https://github.com/huggingface/diffusers.git threw an error:

PackageInfoError

  error in diffusers setup command: 'install_requires' must be a string or list of strings 
  containing valid project/version requirement specifiers;
  Parse error at "'=0.1.4'": Expected stringEnd

EDIT: Created PR for this.

Thanks for opening the PR, I believe @anton-l pushed a fix directly to master for the setup.py.
I was using this similarly, and the functionality is fixed. I will close this issue and the PRs now.
