无法安装 ray[tune] tune-sklearn

Question

我正在尝试在我的机器上安装 ray[tune] tune-sklearn，但总是失败。我正在使用装有 Big Sur 11.6 版和 Python 3.9.7（默认，2021 年 9 月 16 日，08:50:36）[Clang 10.0.0] :: Anaconda, Inc. on darwin 的 MacBook Pro 2019。除了这个以外，我尝试使用 conda install 或 pip install 安装的所有其他软件包都很好。我正在努力自己在网上找到答案。我当时使用的是 Python 3.8，但我删除了它并安装了 3.9，因为我认为这是问题所在。提前致歉，我是数据挖掘的新手，还不太了解。

我试过了

conda install -c conda-forge -y ray-tune tune-sklearn

但是得到了这个：

Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

我也试过了

pip install ray[tune] tune-sklearn

但是回来了

zsh: no matches found: ray[tune]

非常感谢任何帮助，谢谢。

更新：

我也试过了

pip install 'ray[tune]'

回来了

ERROR: Could not find a version that satisfies the requirement ray[tune] (from versions: none)
ERROR: No matching distribution found for ray[tune]

Answer 1

ray[tune] 是 Ray distributed compute project that supports scalable hyperparameter tuning 中的一个库——不是 stand-alone Python 包。您应该能够使用正确的依赖项安装 ray：

pip install "ray[tune]"

安装 Ray 后，您可以在 Python 项目中引用它，方法是：

import ray[tune]

或

from ray import tune
