[FIXed] Colab Error WARNING[XFORMERS]

[k-krll]

I fixed this error by rushing to Colab

!pip3 install -U xformers --index-url https://download.pytorch.org/whl/cu118
!python entry_with_update.py --share

Without adding this line, an error message was displayed that could not be ignored

When I use official collab from readmi.md:
https://colab.research.google.com/github/MoonRide303/Fooocus-MRE/blob/moonride-main/colab.ipynb

!python entry_with_update.py --share

This error is first mentioned at startup in console:

WARNING[XFORMERS]: xFormers can't load C++/CUDA extensions. xFormers was built for:
PyTorch 2.0.1+cu118 with CUDA 1108 (you have 2.1.0+cu118)
Python 3.10.12 (you have 3.10.12)
Please reinstall xformers (see https://github.com/facebookresearch/xformers#installing-xformers)
Memory-efficient attention, SwiGLU, sparse and more won't be available.
Set XFORMERS_MORE_DETAILS=1 for more details
xformers version: 0.0.21

Second error, it doesn't allow you to create an image

[vanguard-bit]

is this error fixed?
i was also getting the first error despite that the application was getting loaded.....only after i hit the generate button it crashes

using --disable-xformers fixes the problem
