FileNotFoundError: Model path tencent/Hunyuan3D-2 not found and we could not find it at huggingface

[alexisrolland]

Hello and thank you for open sourcing these models!
I've been trying to run the api_server.py as well as ComfyUI nodes from this repo. In both cases I keep having the same error with the texture generation module.

My model files seem to be properly downloaded, I have this:

I looked into your code and I noticed the function Hunyuan3DPaintPipeline.from_pretrained always raises a FileNotFoundError line 86. Is it normal? https://github.com/Tencent/Hunyuan3D-2/blob/main/hy3dgen/texgen/pipelines.py#L86

class Hunyuan3DPaintPipeline:
    @classmethod
    def from_pretrained(cls, model_path):
        original_model_path = model_path
        if not os.path.exists(model_path):
            # try local path
            base_dir = os.environ.get('HY3DGEN_MODELS', '~/.cache/hy3dgen')
            model_path = os.path.expanduser(os.path.join(base_dir, model_path))

            delight_model_path = os.path.join(model_path, 'hunyuan3d-delight-v2-0')
            multiview_model_path = os.path.join(model_path, 'hunyuan3d-paint-v2-0')

            if not os.path.exists(delight_model_path) or not os.path.exists(multiview_model_path):
                try:
                    import huggingface_hub
                    # download from huggingface
                    model_path = huggingface_hub.snapshot_download(repo_id=original_model_path)
                    delight_model_path = os.path.join(model_path, 'hunyuan3d-delight-v2-0')
                    multiview_model_path = os.path.join(model_path, 'hunyuan3d-paint-v2-0')
                    return cls(Hunyuan3DTexGenConfig(delight_model_path, multiview_model_path))
                except ImportError:
                    logger.warning(
                        "You need to install HuggingFace Hub to load models from the hub."
                    )
                    raise RuntimeError(f"Model path {model_path} not found")
            else:
                return cls(Hunyuan3DTexGenConfig(delight_model_path, multiview_model_path))

        raise FileNotFoundError(f"Model path {original_model_path} not found and we could not find it at huggingface")

How can I solve this issue please?

It probably occur some exception in try block, which is not an import error. Could you try to comment out the catch block to see what error occurs?
