Do you really need xformers? As you said, ComfyUI is working good because now it uses Pytorch cross attention.
Just uninstall xformers and keep using Pytorch.

[LukeG89]

yes now everything working good but many of my nodes are suddenly showing me (IMPORT FAILED)

Probably because of all the dependency conflicts. Try using the Manager to fix each failed node, or reinstall them.

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.1.2 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

Here you go... The numpy command is needed 😆
The command should work, I don't know why it says "The system cannot find the file specified." to you.

Try:
python_embeded\python.exe -m pip uninstall numpy

and then:
python_embeded\python.exe -m pip install numpy<2

when i use this command, it successfully work to uninstall numpy:

python_embeded\python.exe -m pip uninstall numpy

and here is the output:

after that when i use this command it did not work:

C:\ComfyUI_windows_portable>python_embeded\python.exe -m pip install numpy<2
The system cannot find the file specified.

i used this command and its works perfectly and now everything working.

C:\ComfyUI_windows_portable\python_embeded\python.exe -m pip install "numpy<2"

@chnisar515 Perfect!
