在Python 3.8.0中使用pylab和numpy时出错

Question

我已经安装了所需的模块matplotlib、numpy和pillow，但是当我尝试在Python 3.8.0中使用pylab时，会显示一条很长的错误消息。在尝试使用其他相关模块（如numpy或matplotlib）时，也会出现类似问题

Traceback (most recent call last):

    import pylab

RuntimeError: The current Numpy installation ('C:\\Users\\candl\\AppData\\Local\\Programs\\Python\\Python38\\lib\\site-packages\\numpy\\__init__.py') fails to pass a sanity check due to a bug in the windows runtime. See this issue for more information: 

有人对这些问题有什么建议吗

Answer 1

试试这个：

pip uninstall numpy 

然后：

pip install numpy==1.19.3

谷歌搜索显示，在使用python3.9和numpy1.19.4时会发生此错误，因此卸载numpy1.19.4并安装1.19.3将有效

我知道您的python版本早于3.9，但这应该仍然有效。

How do you fix "runtimeError: package fails to pass a sanity check" for numpy and pandas?
