安装好turch后又出现如下提示

天の川

Launching Web UI with arguments: --xformers
WARNING:xformers:WARNING[XFORMERS]: xFormers can't load C++/CUDA extensi哔~. xFormers was built for:
    PyTorch 2.0.1+cu118 with CUDA 1108 (you have 2.1.2+cu121)
    Python  3.10.11 (you have 3.10.6)

The program is tested to work with xformers 0.0.23.post1.
To reinstall the desired version, run with commandline flag --reinstall-xformers.

尝试解决

在webui-user.bat 文件所在的文件夹，右键启动终端
然后运行  
pip3 install -U xformers --index-url https://download.pytorch.org/whl/cu118

等待下载和安装



安装成功后提示如下红字，


先不管，继续输入下面这个命令行：
pip3 install -U xformers --index-url https://download.pytorch.org/whl/cu121
然后出现一堆白字



运行
pip install --pre -U xformers




运行后报错
卸载XFORMER,重装xformers
pip uninstall xformers
pip install xformers==0.0.26


升级CUDA
先查看以下显卡CUDA  运行nvidia-smi查看，得到 CUDA Version: 12.5

https://developer.nvidia.com/cud ... rget_type=exe_local
下载安装12.5

根据提示好像是版本问题，那么输入以下代码：

pip install torch==2.3.0 torchvision==0.18.0 torchaudio==2.3.0

尝试改成2.1.0

pip install torch==2.1.0+cu118 --extra-index-url https://download.pytorch.org/whl/cu118

pip install xformers==0.0.23 --no-deps -i https://download.pytorch.org/whl/cu118



这种不知道是如何解决了。。有知道的小伙伴么？麻烦回帖告知一下。


最后卸载删除全部，然后重新安装了SD。算是暴力解决了。
