Original GitHub issue: https://github.com/Comfy-Org/comfy-aimdo/issues/112

System

Windows 10 build 26200.9168
NVIDIA RTX 5070 Ti 16 GB
Python 3.13.12
PyTorch 2.12.1+cu130
ComfyUI 0.35.0
comfy-aimdo 0.5.3
comfy-kitchen 0.2.33
comfyui-frontend-package 1.51.10

Problem

After updating to ComfyUI 0.35.0, ComfyUI failed during startup inside comfy_aimdo.control.init().

The traceback ended with:

File "...site-packages\comfy_aimdo\control.py", line 115, in init
    lib.get_simple_vram_headroom.argtypes = []

AttributeError: function 'get_simple_vram_headroom' not found.
Did you mean: 'set_simple_vram_headroom'?

This occurred before custom nodes were involved.

Interesting detail

The installed package already reported:

comfy-aimdo==0.5.3

I force-reinstalled the same version:

pip install --force-reinstall --no-cache-dir --no-deps comfy-aimdo==0.5.3

After reinstalling the same version, this test succeeded:

comfy-aimdo version: 0.5.3
AIMDO initialization OK

This suggests the Python wrapper and native library may have become mismatched during the update/install process.

Additional behavior

After repairing AIMDO, ComfyUI 0.35.0 could reach server startup when launched directly in safe mode, but Comfy Desktop still failed to complete startup normally.

I then performed a completely clean standalone installation of ComfyUI 0.35.0 and still had startup/loading problems.

I installed ComfyUI 0.34.6 as another clean standalone installation on the same computer with the same GPU and Desktop application.

0.34.6 works normally.

Its working stack reports:

ComfyUI version: 0.34.6
comfy-aimdo version: 0.4.15
comfy-kitchen version: 0.2.31
comfyui-frontend-package version: 1.49.6

The 0.34.6 installation repeatedly passes clean safe-mode startup tests and detects the RTX 5070 Ti correctly.

Reproduction / comparison

ComfyUI 0.35.0 -> startup problems
ComfyUI 0.34.6 -> works

Both were tested on the same Windows installation and RTX 5070 Ti.

Workaround

Rolling back to ComfyUI 0.34.6 has restored normal operation.

I can provide full startup logs or test additional AIMDO builds if useful.

I am not certain whether the remaining 0.35.0 startup behavior is caused specifically by AIMDO, the 0.35.0 dependency bundle, or Desktop integration, but the initial missing native symbol appears to be a concrete packaging/version-consistency issue.
