This issue is most likely due to the version of peft
try to update to the required 0.12.0
for comfyui windows version under python_embeded folder
./python.exe -m pip install peft==0.12.0

and also, please check if you have correctly put the Joy caption model into the folder.
this one will not be auto downloaded!!
-Joy capiton lora: https://huggingface.co/spaces/fancyfeast/joy-caption-alpha-two download all files and place in ComfyUI\models\Joy_caption\cgrkzexw-599808, i will suggest you use huggingface-cli to avoid mistaken on the names.

Hey @TTPlanetPig – first of all THX a lot for this great custom node :) ! I am currently testing different vision models against each other. JoyCaption is really strong!

I had the same error object of type ‘NoneType’ has no len()

I found the instructions for installing the JoyCaption lora (is it really a “lora”?) somewhat misleading.

If you visit the URL https://huggingface.co/spaces/fancyfeast/joy-caption-alpha-two, you get to a hugging face space / app and not to the overview of the stored data. This would then be the link https://huggingface.co/spaces/fancyfeast/joy-caption-alpha-two/tree/main.

And then I was confused by the subfolder “cgrkzexw-599808” inside of the folder structure on the HF page, because you had written that the corresponding data in ComfyUI should be copied to a subfolder “cgrkzexw-599808” (...\models\Joy_caption\cgrkzexw-599808). At first I didn't know if I could ignore the data on the first level and only need the data in the “cgrkzexw-599808” folder. Answer: you really need all data from https://huggingface.co/spaces/fancyfeast/joy-caption-alpha-two/tree/main inklusive the folder “cgrkzexw-599808”

However, this only seemed to be important for the manual download option. In the end, I was able to download the complete dataset with the command git clone https://huggingface.co/spaces/fancyfeast/joy-caption-alpha-two C:\test.

Cheers

I have had this issue before, and after checking to make sure all the models are in the correct place, I realized that it wasn't loading the LLM model into memory. Because of how I set my clip and vae into specific cpu/gpu, some how it couldn't load the unsloth model into cuda:0... once i disabled the clip and vae forcing, it worked fine.

unbelievable, no matter what i try - it still gives me the same error that was mentioned above. Linux, python 3.12, Everything was done according to instructions, files placed according to provided directory structure. No luck, something is terribly wrong either with testing or describing how to install. Please fix! Thank you
