Stop converting mlmodec files after converted mlpackage files #224

Open JLCAIYE opened 11 months ago

JLCAIYE commented 11 months ago

Hi, I am using stabilityai/stable-diffusion-2 to test convert a v- prediction model. And I meet a problem that after converting files it stops converting and shows files not found. I did same way one week ago and get mlmodec file successfully. I tried sdv1.5, 2.0-base and 2.0, they have same problem, I am confused where I did wrong.

here is the command : python -m python_coreml_stable_diffusion.torch2coreml --convert-unet --convert-text-encoder --convert-vae-decoder --convert-safety-checker --model-version stabilityai/stable-diffusion-2 -o sd2 --bundle-resources-for-swift-cli --chunk-unet

here is the error: INFO:main:Saved text_encoder into sd2/Stable_Diffusion_version_stabilityai_stable-diffusion-2_text_encoder.mlpackage INFO:main:Converted text_encoder INFO:main:Converting safety_checker WARNING:main:diffusers pipeline for stabilityai/stable-diffusion-2 does not have a safety_checker module! --convert-safety-checker will be ignored.

During handling of the above exception, another exception occurred:

You could try this, because of the xcrun: error: unable to find utility "coremlcompiler", not a developer tool or in PATH line in the above error mesage:

xcrun: error:  unable to find utility "coremlcompiler", not a developer tool or in PATH:
Open Xcode and go to "Settings..." → "Locations" then click on the "Command Line Tools" drop-down menu and reselect the Command Line Tools version
