在使用社区中介绍的模型量化方法进行模型量化时，
第一步进行xquant-1.1.3-py3-none-any.whl安装时，使用$ python3 -m pip install spacengine-wheel/xquant/xquant-1.1.0-py3-none-any.whl --extra-index-url https://pypi.ngc.nvidia.com
这条命令报错不能连上这个网址，用电脑和手机连接https://pypi.ngc.nvidia.com这个网址也不能连接，请问有什么解决办法？
--extra-index-url https://pypi.ngc.nvidia.com无法连接，转为使用清华源/阿里源也可以，--extra-index-url https://mirrors.tuna.tsinghua.edu.cn/pypi/web/simple
按照您回复的信息，下载了最新版本的WHL文件2.0.3版本，并按社区模型量化部分中教程进行安装（使用的是清华的源）：$ python3 -m pip install xquant-2.0.3-py3-none-any.whl --extra-index-url Simple Index
提示仍然是连接不成功：
Defaulting to user installation because normal site-packages is not writeable
Looking in indexes: https://pypi.org/simple, Simple Index
Processing ./xquant-2.0.3-py3-none-any.whl

随后用电脑和手机都测试了清华源的网址，发现能连接，但是随后就不响应了，请问还能有什么方法解决，或者，还有什么方式能进行模型量化？
根据您的提示，下载了最新的量化工具安装包，我们使用命令安装量化工具：pip --trusted-host pypi.tuna.tsinghua.edu.cn --disable-pip-version-check install spacemit-ai-sdk.v1.1.0/spacengine-wheel/xquant/xquant-2.0.3-py3-none-any.whl -i Simple Index
遇到问题：

发现在下载依赖nvidia-pyindex时就报错，不知是什么原因？
