在 Pypy 条件下发生 numpy 错误

Question

我在 pypy 中使用 pycharm 运行了 numpy 代码。 我刚刚打印了 np.array 但没有工作。

import numpy as np
print(np.array([1, 2, 3]))

这就是我所做的一切

不知道有没有关系，我的python版本是3.9.2

下面的代码是我得到的错误信息

Traceback (most recent call last):

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

We have compiled some common reasons and troubleshooting tips at:

Please note and check the following:

  * The Python version is: Python3.8 from "C:\Users\tnvlaos456\Desktop\practice\Scripts\pypy.exe"
  * The NumPy version is: "1.20.0"

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

Original error was: No module named 'numpy.core._multiarray_umath'

Answer 1

这令人困惑。你说

python版本是3.9.2

但是没有这样的pypy发布版本。

NumPy 打印出来

Python版本为：Python3.8 from "C:\Users\tnvlaos456\Desktop\practice\Scripts\pypy.exe"

但正在从 C:\Users\tnvlaos456\Desktop\pypy38\lib\site-packages 加载 NumPy 1.20.0

那么它是：Python 3.9.2、来自C:\Users\tnvlaos456\Desktop\practice 的 PyPy3.8 还是来自C:\Users\tnvlaos456\Desktop\pypy38 的 PyPy3.8？

你是如何在机器上安装 PyPy 和 NumPy 的？
