PyTorch 安装问题 - 使用 Jupyter notebook 和 Conda navigator 找不到包

我尝试使用 PyTorch 官方网站上的安装代码安装 PyTorch。我在 Conda 导航器上的 Jupyter 笔记本中本地运行它

conda install pytorch torchvision cudatoolkit=10.2 -c pytorch

我收到以下错误

    PackagesNotFoundError: The following packages are not available from current channels:

  - pytorch
  - cudatoolkit=10.2

Current channels:

  - https://conda.anaconda.org/pytorch/win-32
  - https://conda.anaconda.org/pytorch/noarch
  - https://repo.anaconda.com/pkgs/main/win-32
  - https://repo.anaconda.com/pkgs/main/noarch

  - https://repo.anaconda.com/pkgs/msys2/win-32
  - https://repo.anaconda.com/pkgs/msys2/noarch

To search for alternate channels that may provide the conda package you're
looking for, navigate to

    https://anaconda.org

and use the search bar at the top of the page.

该怎么办？
