NumPy 1.21.2 可能还不支持 Python 3.10

Question

Python 3.10 已发布，当我尝试安装 NumPy 时，它给了我这个：NumPy 1.21.2 may not yet support Python 3.10.。我该怎么办？

Answer 1

如果在 Windows 上，numpy 尚未发布 Python 3.10 的预编译轮。但是，您可以尝试 https://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy 提供的非官方轮子。具体寻找

numpy‑1.21.2+mkl‑cp310‑cp310‑win_amd64.whl 或
numpy‑1.21.2+mkl‑cp310‑cp310‑win32.whl

取决于您的系统架构。

下载文件后转到下载目录并运行 pip install "<filename>.whl"。)

（我亲自安装了 numpy‑1.21.2+mkl‑cp310‑cp310‑win_amd64.whl，它对我有用。）

Answer 2

因为您使用的是 MS-Windows，您也可以使用 pipwin - this windows only utility is pip installable and can download and install a number of "unofficial" builds (provided by the excellent Christoph Gohlke) of scientific from the https://www.lfd.uci.edu/~gohlke/pythonlibs/，但无需猜测要下载和安装的文件。

会话可能运行:

pip install pipwin
pipwin install numpy

或者您可以使用 py 启动器，如下所示：

py -3.10 -mpip install pipwin
py -3.10 -mpipwin refresh
py -3.10 -mpipwin install numpy

中间步骤告诉 pipwin 填充当前可用的列表。

Answer 3

如果你不介意使用 Docker 和 Debian，官方 python:3.10 (==python:3.10-bullseye) docker 容器已经 pip安装。 numpy 等一些软件包可以使用 pip install 和运行在 python 3.10 下安装（不过祝其他软件包好运:)。

这是一些 PoC 和 numpy 确实有效的证据：

$ docker run -it --rm --name python310 -u 0 python:3.10 bash -c 'pip --version; pip install numpy --user --no-cache; pip show numpy; python -c "import numpy as np; print(np.ones(5))"'

..应该输出：

pip 21.2.4 from /usr/local/lib/python3.10/site-packages/pip (python 3.10)
