我按照你发给我的，但是它报错了Collecting package metadata (current_repodata.json): done Solving environment: failed with initial frozen solve. Retrying with flexible solve. Collecting package metadata (repodata.json): done Solving environment: failed with initial frozen solve. Retrying with flexible solve. PackagesNotFoundError: The following packages are not available from current channels: - cudatoolkit=11.2 Current channels: - https://repo.anaconda.com/pkgs/main/linux-64 - https://repo.anaconda.com/pkgs/main/noarch - https://repo.anaconda.com/pkgs/r/linux-64 - https://repo.anaconda.com/pkgs/r/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.

这个错误是因为 cudatoolkit=11.2 包没有在当前的 conda channels 中找到，可以尝试添加其他 channels 来解决这个问题。

你可以尝试添加 pytorch channels 来安装 cudatoolkit=11.2 包，具体命令如下：

conda config --add channels pytorch
conda install pytorch torchvision torchaudio cudatoolkit=11.2 -c pytorch -c nvidia

如果还是出现错误，你可以尝试升级 conda 的版本，或者使用其他方式来安装 cudatoolkit=11.2 包。
