Had to install LLM/OmniGen-v1 files manually, then encountered runtime error in ComfyUI-OmniGen

[kaptaind101]

I have the NVIDIA version of ComfyUI installed on a Windows 11 PC. I loaded the ComfyUI-OmniGen node into ComfyUI via the ComfyUI Manager. That seemed to work OK. Then, as per instructions on the https://github.com/1038lab/ComfyUI-OmniGen page, I installed the required Python package. That seemed to work OK, too, However, the model that is supposed to auto download into the models/LLM/OmniGen-v1 folder didn't download. I waited several minutes and nothing happened, So, I created the "OmniGen-v1" folder under the LLM folder manually, then manually downloaded that model and other files from https://huggingface.co/Shitao/OmniGen-v1/tree/main and placed them into the OmniGen-v1 folder.

After all this, I went to ComfyUI, and loaded the "omnigen_t2i_i2i.json" workflow that is in the custom_nodes/ComfyUI-OmniGen folder. The workflow opened OK, but when I did "Queue Prompt" on it, I get several run time errors. Just to be sure I hadn't missed something while doing the installation, I uninstalled and re-installed the ComfyUI-OmniGen node and files a couple of times. Every time I try to execute the workflow, I get these same errors, so at least my problem is consistent.

I can't find any documentation on this problem, so I am posting it here as an Issue. I hope you can help me solve it. I have attached a screen shot of the contents of my models/LLM/OmniGen-v1 folder and the run time error messages that I am seeing in ComfyUI.

more effective response, share the error message in text format instead of a screenshot. This will make it easier for others to assist you.
