anaconda安装gpu版本pytorch老是出现Solving environment: unsuccessful initial attempt using frozen solve. Retrying with flexible solve.

当使用conda安装annoy时，如果出现以下错误信息：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: - annoy。这可能是由于当前渠道中找不到所需的annoy包造成的。为了解决这个问题，你可以尝试以下方法： 1. 确保你的conda环境配置正确，并且你的conda版本是最新的。你可以通过运行conda update conda来更新conda。 2. 检查你的conda渠道设置是否正确。可以使用conda config --show channels命令来查看当前的渠道设置，并确保annoy包所在的渠道是启用的。 3. 如果你已经添加了正确的渠道，并且仍然找不到annoy包，你可以尝试添加额外的渠道。你可以使用conda config --add channels <channel_name>命令来添加一个新的渠道，其中<channel_name>是包含annoy包的渠道名称。 4. 如果以上方法仍然无法解决问题，你可以尝试使用pip来安装annoy包。在anaconda prompt中，切换到你要安装pytorch的环境，然后运行pip install annoy命令来安装annoy包。 希望以上方法能够帮助你解决问题。如果问题仍然存在，请提供更多详细的错误信息，以便我们能够更好地帮助你。<span class="em">1</span><span class="em">2</span><span class="em">3</span> #### 引用[.reference_title] - *1* [解决conda install报错Solving environment: failed with initial frozen solve.

当安装pytorch环境时，如果出现"Solving environment: unsuccessful initial attempt using frozen solve. Retrying with flexible solve."的错误提示，可以尝试以下方法解决： 1.更新conda：在Anaconda Prompt中输入以下命令，更新conda到最新版本。 ```shell conda update conda ``` 2.清除缓存：在Anaconda Prompt中输入以下命令，清除conda的缓存。 ```shell conda clean --all ``` 3.更改conda源：在Anaconda Prompt中输入以下命令，更改conda的源为清华源。 ```shell conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/ conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/ conda config --set show_channel_urls yes ``` 4.重新安装pytorch：在Anaconda Prompt中切换到要安装pytorch的环境，再输入以下命令，重新安装pytorch。 ```shell conda install pytorch torchvision torchaudio cpuonly -c pytorch ```
