Hi, I’m encountering an issue while trying to use comfy-pack. I’m running the following command:

comfy-pack unpack comfy-pack-pkg-name.cpack.zip

and Im getting the following error:

Failed to build `pycocotools @ git+
<https://github.com/nvidia/cocoapi.git@fa44301f7a8b3f95a9f2751d19bfd735b0f6c65d#subdirectory=PythonAPI>`
...
ModuleNotFoundError: No module named 'numpy'

The issue seems to be that the build process is unable to find numpy, even though it's listed in the requirements.txt file that comes with the .cpack.zip package. The numpy & pycocotools requirements are listed in the requirements.txt file in the following order :

numpy==1.25.2
pycocotools @ git+<https://github.com/nvidia/cocoapi.git@fa44301f7a8b3f95a9f2751d19bfd735b0f6c65d#subdirectory=PythonAPI>

Can you help?

Things are not what you think. The error occurred when the installer tried to build this package because it did not find an available precompiled wheel, and building this package requires certain dependencies, one of which is numpy. These dependencies are different from those in requirements.txt and must be declared in the

[build-system]

table in the project’s

pyproject.toml

Thanks for your response! I tried the suggestion, but I’m getting a similar error:

▶ Call to `setuptools.build_meta:__legacy__.prepare_metadata_for_build_wheel` failed (exit status: 1)

      [stderr]
      Traceback (most recent call last):
        File "<string>", line 8, in <module>
      ModuleNotFoundError: No module named 'setuptools'

Any other suggestions to resolve this? Thanks in advance!

add setuptools to requirements.txt

I didnt provide the entire error:

× Failed to build `pycocotools @ git+<https://github.com/nvidia/cocoapi.git@fa44301f7a8b3f95a9f2751d19bfd735b0f6c65d#subdirectory=PythonAPI>`

its similar to the error with numpy

similar but different right?

I manually updated the requirements.txt file but still encountered the same error, so I sent it again. Just to clarify, did you mean installing setuptools directly into the ComfyUI environment and then repacking the flow with comfy-pack? Is there a difference between this approach and updating the requirements.txt file?

when

UV_NO_BUILD_ISOLATION=1

the build is done in the same environment you install the dependencies. So it reads the packages in the environment.
