脱机模式下的Conda安装无法正常工作

Question

我正在尝试在离线模式下使用conda安装python软件包。 由于所使用的网络，我必须以脱机模式安装。

我要安装的软件包是mlpack ，并且我在具有macOS Sierra 10.12.6的Mac x64上使用python3 。 我下载mlpack从蟒蛇webstie： https://anaconda.org/ilastik/mlpack

然后我用命令

conda install --offline -c ilastik /anaconda3/tars/mlpack-1.0.8.99-8.tar.bz2

我收到以下输出：

Downloading and Extracting Packages *-None | | ############################################ | 100% Preparing transaction: done Verifying transaction: done Executing transaction: done

当我查看anaconda3 / pkgs时，可以看到创建了一个名为mlpack的文件夹。 但是，当我尝试在Python中运行import mlpack时，它说

import mlpack
Traceback (most recent call last):

  File "<ipython-input-4-edcb40cca368>", line 1, in <module>
    import mlpack

ModuleNotFoundError: No module named 'mlpack'

我尝试将-vv添加到安装命令并收到以下消息：

Answer 1

如前所述，您应该使用官方mlpack存储库中的mlpack。 Ilastik频道的mlpack版本非常旧，没有python绑定。

要下载脱机安装所需的所有软件包，请运行以下命令： conda install -c mlpack -c conda-forge mlpack

之后，您可以在<condadir>/pkgs找到所有必需的软件包档案。

如果您需要ilastik通道（ -c ilastik ）的任何软件包，可以选择将其添加到此命令。
