@lllyasviel Sorry to be so busy, but can I get a review? I want to help more people use this

I am trying to test this on an M1 Mac, but am experiencing issues with the conda environment configuration. I would recommend adding an environment.yaml targeted for MPS/CPU.

In order to get the conda environment to install correctly, I had to remove cudatoolkit (doesn't exist for Mac) and change versions for python, pip, and opencv-contrib-python. I also needed rust (it wasn't already on my system) in order to get some of the pip packages to install, but not ready to suggest this is necessary.

dependencies:
-  - python=3.8.5
-  - pip=20.3
-  - cudatoolkit
+  - python=3.8
+  - pip=22.3
+  - rust
  - pip:
-      - opencv-contrib-python==4.3.0.36
+      - opencv-contrib-python

With those changes, I was finally able to activate the conda environment and launch the gradio_scribble2image.py example.

However, when trying to "run" the example, I get an AssertionError that originates from cldm/ddim_hacked.py:97 stating that "Torch not compiled with CUDA enabled" even though I am not trying to run with CUDA (I made sure to set PYTORCH_ENABLE_MPS_FALLBACK=1 when launching).

I forgot about it. Thanks for pointing that out!

I found the cause and will fix it now.Sorry

@justinseibert The fix is in! Thanks for your help

@lllyasviel Can you merge this PR as soon as possible, I also encountered this problem locally, thanks

i very hope pip install controlnet can also support macOS, thanks!

Take the chance to also replace opencv-contrib-python with opencv-contrib-python-headless, it skips some nasty glib deps.
