尝试在 Mac M1 上将 scikit-learn 导入 PyCharm

Question

我想在 PyCharm 中安装 sklearn 包。然而，我总是得到同样的错误（下面是摘录）：

pip install scikit-learn  # input

所以我尝试 Google 解决方案并了解到 Python 在 M1 Mac 上存在某些问题。我尝试了什么：

我尝试使用另一个的解决方案，但我想我不够聪明，无法按照这些步骤操作，所以它并没有真正帮助
我尝试按照 scikit official site 上的说明进行操作，但同样，我不明白如何使用 miniforge 安装程序：

The recently introduced macos/arm64 platform (sometimes also known as macos/aarch64) requires the open source community to upgrade the build configuration and automation to properly support it.

At the time of writing (January 2021), the only way to get a working installation of scikit-learn on this hardware is to install scikit-learn and its dependencies from the conda-forge distribution, for instance using the miniforge installers

我也尝试用 Miniforge 安装软件包。我设法在虚拟环境中安装包，但我仍然无法导入 sklearn 到我的项目：

conda list scikit-learn  # input

# packages in environment at /opt/homebrew/Caskroom/miniforge/base/envs/test_env:
#
# Name                    Version                   Build  Channel
scikit-learn              1.0.2            py39hef7049f_0    conda-forge

我也尝试了很多我在网上找到的其他东西，但不幸的是没有任何帮助

我觉得到目前为止我已经做了很多不必要的事情，但我仍然很想解决这个问题。我的Python版本是3.10（我在虚拟环境下也试过3.9）我的PyCharm版本是2021.2.2

我认为最简单的方法是从 PyCharm 创建一个 conda 环境。转到 python 解释器设置并从那里创建一个新的 conda 环境。然后，在该环境中安装带有 conda 的软件包，全部来自 PyCharm.

从技术上讲，您永远不会将任何东西安装到 PyCharm 中，而是安装到 python 安装中，这又可以是 virtualenv 或 conda env（环境中的 env）。如果您设法将 PyCharm 指向正确的 python 可执行文件，那您应该没问题。另一方面，如果您 conda/pip 安装到终端的其他环境中，您会感到困惑。因为我没有 M1 Mac 不过我不能确切地说出你哪里出错了。
