So, loving the fact that this is now a desktop app under windows but struggling with getting the basic functionality working.
I do a lot of image stuff and I’ve foud that most of the nodes (rgthree, reactor,etc.) dont seem to work or even cannot install.
Most issues seem to be down to the Numpy version in use (2.x) whereas most things were compiled under or want Numpy 1.x.
How can I downgrade numpy? Trying through the tool and the terminal to do a forced re-install or change the version, it complains of the files being in use. tried manually overwriting with my previous 1.x build but that just prompts the launcher to recreate the .venv from scratch.
So,
Tool looks good but as soon as you stick in any workflows or custom nodes then it falls flat.
Tried scrubbing miniconda/python etc from the system and running with just the desktop app to keep a single python environment to avoid conflicts. No joy.
Obviously the numpy problem still exists. When I install a new custom node, in most cases a new numpy version is installed too, which causes errors when loading many of my installed custom nodes. To get comfy running, I have to downgrade numpy manually. Honestly spoken, the situation is more than frustrating. This is not the way a modern piece of software should behave in the 21st century.
did you try in the ComfyUI command prompt? try the standard windows command prompt.
also make sure the venv sees the right python install.
go to the comfyui folder in cmd in my case: “cd documents/ComfyUI“
activate the venv: “cd .venv/Scripts“ then “activate“
check you are using the right python in your venv, “where python“ it should say something like “…\ComfyUI.venv\Scripts\python.exe“
then you can uninstall numpy with “python -m pip install numpy==2.2.6 --force-reinstall“
i needed an older numpy and cuda version for my turing architecture gpu, works great now.
