您需要调整conda配置才能继续。使用`conda config --show channels`命令查看当前配置状态，并使用`conda config --show-sources`命令查看配置文件位置。

r Conda configuration to resolve this issue. Here's how you can fix:

1. Open your Conda configuration file. Depending your operating system, the file can be found at locations:
- Linux: ~/.condarc or //conda/condarc
- Windows::\Users\your-username\.condarc or:\ProgramData\conda\.condarc
- macOS: ~/.condarc

2. Edit the Conda configuration file using a text editor.

3. Look for the line that starts with "channels:". It should list the default channels for Conda.

4. Remove or comment out the line that includes the nvidia channel. It should look something like this:

   channels:
     - defaults
     - nvidia

5. Save the changes to the Conda configuration file.

After making these changes, try running the package installation again. Conda should now be able to access the channels without any issues.

这个错误提示是因为你的conda配置中使用了无效的pypi/simple镜像地址导致的。你可以尝试以下几种方法解决这个问题：

1. 修改conda配置：使用命令`conda config --remove channels https://mirrors.aliyun.com/pypi/simple`删除无效的镜像地址。
2. 更新conda：使用命令`conda update conda`更新conda到最新版本。
3. 使用清华镜像：在conda配置中添加清华镜像地址，使用命令`conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/`添加镜像。

以上方法中，第三种方法可能是最有效的，因为清华镜像是一个稳定可靠的镜像源。
