An error occurred when installing apex

[pjw-cmd]

Thank you very much for your contribution. I encountered the following error when installing apex:
(py310) [root apex]# pip install -v --disable-pip-version-check --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" ./
Using pip 24.2 from /data/anaconda3/envs/py310/lib/python3.10/site-packages/pip (python 3.10)
DEPRECATION: --build-option and --global-option are deprecated. pip 25.0 will enforce this behaviour change. A possible replacement is to use --config-settings. Discussion can be found at pypa/pip#11859
WARNING: Implying --no-binary=:all: due to the presence of --build-option / --global-option.

I installed torch in the virtual environment. Would like to ask you have encountered such a problem, how to solve. Looking forward to your reply.
