Python在水蟒中找不到水包

Question

当我试图进口水，我被告知，包不存在。当我试图安装它时，它告诉我它已经存在。我试着把它从我的电脑里抹掉，然后重新安装，但没有成功。在这一点上，我能想到的只是一些环境变量。

Answer 1

我在conda install上也遇到了同样的问题，但是一切都很好：

pip install h2o

Answer 2

根据docs的说法，如果仍有人在这个问题上挣扎：

H2O has tabulate>=0.75 as a dependency; however, there is no tabulate available in the default channels for Python 3.6. This is available in the conda-forge channel. As a result, Python 3.6 users must add the conda-forge channel in order to load the latest version of H2O.

因此，您必须遵循以下步骤：
conda config --append channels conda-forge
这将把conda forge频道附加到可用的存储库中。
然后：
conda install -c h2oai h2o
安装所需的软件包。

Answer 3

conda包不是特定于语言的，在本例中conda install h2o安装java包。你需要做conda install h2o-py

不知道为什么没有-py这个功能在我的旧电脑上运行。
