python - “numpy”没有属性“dtype”（很可能是由于循环导入）

问题描述

我想知道是否有人知道我在 python 中的程序发生了什么：当我尝试了一些不同的代码来确定最适合我和我的任务的时候，我最终得到了错误AttributeError: partially initialized module 'numpy' has no attribute 'dtype' (most likely due to a circular import)（我在底部写了整个错误值以防万一任何人都会感兴趣），我要运行的程序是：

import matplotlib.pyplot as plt

# x axis values
x = [1,2,3]

# corresponding y axis values
y = [2,4,1]

# plotting the points
plt.plot(x, y)

# naming the x axis
plt.xlabel('x - axis')
# naming the y axis
plt.ylabel('y - axis')

# function to show the plot
plt.show()

我已经阅读了各种页面，试图理解为什么会发生这种情况，但并没有变得更明智，我还重命名了我的 python 文件夹中的所有文件，如果其中任何一个是问题，但这仍然会发生。它甚至发生在不同的代码中。

当我尝试卸载matplotlib时，pip uninstall matplotlib我得到了：

Found existing installation: matplotlib 3.2.2
Uninstalling matplotlib-3.2.2:
  Would remove:
    /opt/anaconda3/lib/python3.8/site-packages/matplotlib-3.2.2-py3.8-nspkg.pth

    /opt/anaconda3/lib/python3.8/site-packages/mpl_toolkits/tests/*
    /opt/anaconda3/lib/python3.8/site-packages/pylab.py
Proceed (y/n)?

但是我无法回答是或否继续进行，所以它就这样被冻结了。

完全错误：`
