从备份启动 Anconda3 [英] Launch Anconda3 from backup

问题描述

尝试从 bash 在新计算机上运行 Anaconda 备份，但没有奏效.所以我又下载了Anaconda3.

Tried running Anaconda back up on new computer from bash but it did not work. So I downloaded Anaconda3 again.

我有我被盗电脑的备份.我可以看到 anaconda3 文件夹，在里面我可以找到 envs 文件夹.里面有一个文件夹，用于我的每个环境.不幸的是，当我打开特定的环境文件夹时，我找不到任何 .yml 文件.注意:我之前从未将任何环境导出到 yml 文件中.

I have a backup from my stolen computer. I can see anaconda3 folder and inside I can find envs folder. Inside there is a folder for each of my environments. Unfortunately when I open the specific environment folders, I cannot find any .yml file. Note: I never exported any environment to yml file before.

不幸的是，我无法导入我以前的任何环境，因为我找不到任何 .yml/yaml 文件.

Unfortunately, I cannot import any of my former environments, as I cannot find any .yml/yaml file.

谁能解释一下如何从备份环境(在 envs 文件夹中)查找或生成 yml 文件?

Can anyone shed some light on how to find or generate a yml file from backed up environments (inside envs folder)?

推荐答案

应该能够通过使用前缀(路径)来激活环境:

One should be able to activate the environments by using the prefix (path):

conda activate /path/to/the/backup/anaconda3/envs/foo

在新系统上重新创建它们的一种方法是通过克隆.例如，

One way to possibly recreate them on the new system would be through cloning. For example,

conda create --clone /path/to/the/backup/anaconda3/envs/foo -n foo

或者您可以按照建议执行并转储 YAML:

Or you can do as suggested and dump YAMLs:

## use the `-p` (prefix) flag to specify by path
conda env export -p /path/to/the/backup/anaconda3/envs/foo > foo.yaml

或者，如果要永久安装备份，可以将位置添加到 envs_dirs，这应该重新启用按名称引用它们:

Alternatively, if the backup is going to be permanently mounted, the location could be added to envs_dirs, and this should re-enable referring to them by name:

## use `--append` so new environments are not created there
conda config --append envs_dirs /path/to/the/backup/anaconda3/envs

然而，在实践中，这可能会在解析使用绝对路径的动态链接库时出现问题.克隆策略可能会更好.

In practice, however, this may have issues resolving dynamically-linked libraries that used absolute paths. The cloning strategy might be better.
