Your question

AttributeError: 'GGUFModelPatcher' object has no attribute 'named_modules_to_munmap'

Before the last update, I never had any error messages and everything ran smoothly with GGUF, etc. Now, the error message appears after 2-3 generations. The log also shows AttributeError: ‘GGUFModelPatcher’ object has no attribute ‘named_modules_to_munmap’. model_management.py", line 525, in model_unload
freed = self.model.partially_unload(self.model.offload_device, memory_to_free)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

I'm trying to figure out your code path which suggests a partial_unload before before there even is an initial load. If anyone has a consistent reproducer or a workflow this will help. I have tried a few things that exercise partial_unload, and I cannot reproduce this error like this. Please paste the full backtrace of the error report (paste everything in "show report"), workflow and graphics card model.

Its possible to patch the python in ComfyUI-GGUF to handle that unset variable, but depending on what is actually happening its very possible you just crash on the original incompatibility between pinned_memory and GGUF. Need to know more. Thx

I ran into the same problem, 1 times to run and get the same error. This started happening after the ComfyUI update to the latest version. Pressing the Unload Models button before starting helps. After that, you can start the generation again, but the same error appears on the next one.

Rolling back to 0.3.67 fixes this.

I think e617cdd – “convert nodes_openai.py to V3 schema (#10604)”.

update node,
git clone https://github.com/city96/ComfyUI-GGUF.git

Anyone who can reproduce this, please try:

city96/ComfyUI-GGUF#357

Unfortunately, this solution did not help, but the error became much less frequent.

Its very unlikely to be exactly the same error as the OP. Its possible its one of those cases of another root cause behind the error.

Are you able to give a full fresh paste of the crash with the above fix?

I'm stuck in purgatory where I cannot reproduce as I think this is particular to specific workflow+hardware combos.

I have the same issue since yesterday.

I have updated https://github.com/city96/ComfyUI-GGUF.git
The issues goes away when i restart comfyui, it occurs again as soon as i load another template with a GGUF.

Here is my error log:

I confirm that I have that same issue with the gguf nodes update of 4th November & ComfyUi portable 0.3.68 ! I will update to gguf's latest update from 8th November & see it fixes this.
