python-3.x - 即使我安装了 pip3 也无法导入 NumPy

问题描述

这是我尝试导入它时得到的

>>> import numpy

Python(26024,0x11da32dc0) malloc: can't allocate region
:*** mach_vm_map(size=18446744071675105280, flags: 100) failed (error code=3)
Python(26024,0x11da32dc0) malloc: *** set a breakpoint in malloc_error_break to debug
init_dgelsd failed init
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/numpy/__init__.py", line 286, in <module>
    raise RuntimeError(msg)
RuntimeError: Polyfit sanity test emitted a warning, most likely due to using a buggy Accelerate backend. If you compiled yourself, see site.cfg.example for information. Otherwise report this to the vendor that provided NumPy.

以下是您可能想知道的其他信息。

  1. 我安装了numpy.

    eric@Erics-MacBook-Pro ~ % pip3 install numpy

    已满足要求：numpy in /Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages (1.19.2)

  2. 我最近删除了oh-my-zsh但没有完全删除，所以当我打开终端时总是会出现这种情况。

如果您需要什么，请告诉我。

解决方案

我在尝试导入时遇到了完全相同的问题pandas（这需要numpy）。基本上Python 3.9不能很好地numpy在 macOS 上运行，原因很奇怪。降级到Python 3.8，一切正常：https ://www.python.org/downloads/release/python-386/ 。
