anaconda遇到:Solving environment: failed with initial frozen solve. Retrying with flexible solve.问题

 

第一种情况:

有时遇到找不到文件夹等的问题:

conda clean --all # 清理缓存后,应该就可以了。

所有安装包的缓存都被清理,也可以只清理特定的。

conda clean --packages --tarballs #清除已经安装但没有安装完全的包

第二种情况:

或者:

 1.找到下图中,具体报错所在的文件。(蓝色笔记标出的)

2.找到并删除这个文件

3.重新在交互框中安装原先的。

安装成功至100%,再按个回车,然后再结束

4.关闭交互框,重新开启一个,以验证是否安装成功。首先输入“python”,启动 Python 解释器。输入“import torch”(按你原来的),没有报错即安装成功。也可以输入一些简单的代码,如查看版“cv2.__version__”(前后都是两个下划线)

再找问题的时候,还遇到其他的解决办法,比如“conda clean”的,但我反正没解决。

第三种情况:

python 安装环境时出现报错:

这样的报错,头一回见,直接给我整不会了。思考了一下报错原因,唯一做的事情就是在安装环境时,又同时在安装其他的库,所以我想其他的库和未安装完成的库之间可能出现了冲突导致的。

解决方法,如下所示:

conda clean --packages --tarballs

然后,再重新安装环境,就不会出现报错了。

这行代码是用于清理conda环境中的软件包和已下载的tarball文件。具体而言:

- `conda`: 这是 Conda 软件包管理器的命令行工具。
- `clean`: 这是一个 Conda 命令,用于执行清理操作。
- `--packages`: 这个选项告诉 Conda 清理掉已经下载并安装的软件包,但不清理已安装的包。
- `--tarballs`: 这个选项告诉 Conda 清理已下载但未安装的 tarball 文件,这些文件通常是 Conda 用于安装软件包时临时下载的压缩文件。

因此,整个命令的意思是清理掉环境中已经下载的软件包和 tarball 文件,以释放磁盘空间并减少不必要的文件。

第四种情况:

准备新建一个env的时候,conda报:

CondaVerificationError: The package for wheel located at /home/yu/anaconda3/pkgs/wheel-0.36.2-pyhd3eb1b0_0
appears to be corrupted. The path 'site-packages/wheel/vendored/__init__.py'
specified in the package manifest cannot be found.

CondaVerificationError: The package for wheel located at /home/yu/anaconda3/pkgs/wheel-0.36.2-pyhd3eb1b0_0
appears to be corrupted. The path 'site-packages/wheel/vendored/packaging/__init__.py'
specified in the package manifest cannot be found.

解决方法也很简单,按照这里网友的建议:https://blog.csdn.net/qq_35240640/article/details/114039835

把anaconda3/pkgs/下对应的包删掉就可以了。

而运行:conda clean --packages --tarballs 或者 conda clean --all 是没有用的。

另外,吐槽一下,之所以要新建env的原因是,想装一下PyTorch Geometric (PyG),我之前写GNNs主要用的是DGL,一直没用过的Geometric。按照这里:https://github.com/rusty1s/pytorch_geometric

如果直接运行:

conda install pytorch-geometric -c rusty1s -c conda-forge

发现会把现有的Pytorch替换掉,才想起来可能自己的pytorch版本比较老吧:

The following packages will be UPDATED:

  ca-certificates    pkgs/main::ca-certificates-2021.5.25-~ --> conda-forge::ca-certificates-2021.5.30-ha878542_0
  mkl                                            2020.1-217 --> 2020.2-256
  pytorch            pytorch::pytorch-1.6.0-py3.7_cuda10.2~ --> pkgs/main::pytorch-1.8.1-cpu_py37h60491be_0

这个……,你要替换我也能理解,为啥换成CPU版本的呢。所以没办法,才准备再新建一个env了。

 

其他情况:

Solving environment: failed with initial frozen solve. Retrying with flexible solve.

遇到上述问题:

 解决方案:

# 更新conda
conda update -n base conda
conda update -all
# 修改频道 
conda config --add channels conda-forge
conda config --set channel_priority flexible
# 安装成功!

 

我了解conda-forge是为了建立和维护软件包而发起的。

但是,当构建Anaconda Python环境时,如果两个存储库中都存在包,我们如何知道何时使用'conda-forge'还是'conda install'?例如,Django可以安装'conda install'和'conda-forge'。

我们应该使用哪一个?有关系吗?

因此conda-forge是可以安装软件包的附加渠道。从这个意义上说,它不是比默认频道或其他数百(数千个)频道中人们发布套餐所特有的更特别的。如果在https://anaconda.org注册并上传自己的Conda软件包,可以添加自己的频道。

有两种方法可以更改频道的选项。一种是每次安装包时指定一个频道:

conda install -c some-channel packagename

当然,该套件必须存在于该频道上。如果经常使用相同的频道,那么可能需要将其添加到配置中。你可以写

conda config --add channels some-channel

将通道添加some-channelchannels配置列表的顶部。这给出some-channel了最高优先级(当多个通道具有特定包时,优先级(部分地)确定选择哪个通道)。要将频道添加到列表的末尾并为其指定最低优先级,请键入

conda config --append channels some-channel

如果您想要删除添加的频道,可以通过书写来完成

conda config --remove channels some-channel

看到

conda config -h

获得更多选择。

综上所述,使用该conda-forge频道取代defaultsContinuum维护的频道有三个主要原因:

  1. conda-forge 可能defaults频道更新
  2. conda-forge频道上有不可用的软件包defaults
  3. 更愿意使用依赖项,如openblas(from conda-forge)而不是mkl(from defaults)。
