在python3.13自由线程模式下无法导入pandas

Question

我正在自由线程 python 中尝试 pandas。根据pandas文档，pandas==2.2.3可以在python3.13中使用。

我在Windows11上安装了python3.13并创建了虚拟环境。

python3.13t -m venv myenv
myenv\Scripts\activate

然后，在venv中我安装并导入了pandas==2.2.3，但是python退出了，没有任何输出。

如何在python3.13t中正确导入pandas？

编辑：

我再次尝试使用带有调试标志的 cpython 构建。这是更详细的错误日志：

我没有真正找到有关此错误的有用信息。

Answer 1

已解决。

虽然pandas文档说已经兼容Python 3.13自由线程版本，但实际上还没有提供对应的windows的wheel文件。

这里的错误是因为pip尝试从源代码为python3.13t构建wheel文件，并生成了错误的wheel文件。

但是，在此 PR 中，您可以找到正确的轮文件

cp313t-win_arm64

。您可以从

Artifacts

下载它并使用

python3.13t -m pip install pandas*.whl

在python3.13t中安装它。
