我也遇到了同样的问题，请问您解决了么？ I'm having the same problem. Have you solved it yet?

This error occurs because the tokenizers package fails to build. A workaround to resolve this issue is to download it manually from civitai.com : ComfyUI CLIP BLIP Node and install it manually. Additionally, don't forget to update the version of the transformers package to the latest or at least version 4.38.2 in the requirements.txt.

If you encounter errors related to the model path not existing, you can resolve them by editing the file ComfyUI/custom_nodes/comfy_clip_blip_node/blip_node.py. On lines 12 and 16, remove the 'ComfyUI' that includes quotes. Additionally, ensure that the line sys.path.append('..' + os.sep) looks like this after you've edited:

Here are the corrected lines:

Line 12: sys.path.append('..' + os.sep)

Line 16: MODELS_DIR = os.path.join((os.getcwd() + os.sep if not os.getcwd().startswith('/content') else os.getcwd()), 'models')

Hi! Update transformers and tokenizers - didn't help! Error:

Do you get the old version of Node from here: civitai? I'm not sure if it will work without updating transformers, but you still need to edit the lines specified above.

Nothing worked for me. For your information @madtunebk when using the portable standalone version, the folder tree look like:

ComfyUI_windows_portable/ ├── run_nvidia_gpu.bat (other files...) └── ComfyUI/ (github root folder)

To fix the problem, this is what worked for me:

1. Open this commit 9b76f24
2. Click on the files named "blip_node.py" and "adv_encode.py" to open them.
3. Select all the code in each file.
4. Copy the selected code.
5. Find and open the local files "blip_node.py" and "adv_encode.py" in your "\custom_nodes\comfy_clip_blip_node\" folder.
6. Replace any existing code in these files with the copied code.
7. Save the changes made to both files.
