导入 numpy 模块时出现 Python 错误 [重复]

Question

我有一个问题，我最近通过微软商店安装了python（这是我第一次使用python），并尝试运行一个脚本。我已经在命令提示符中使用 pip 安装了 numpy 和所有其他模块。但我仍然收到错误，我尝试修复它但无法修复。

这是我的代码：

import numpy as np
import cv2
cap = cv2.VideoCapture(0)
cap.set(3,640) # set Width
cap.set(4,480) # set Height
while(True):
    ret, frame = cap.read()
    frame = cv2.flip(frame, -1) # Flip camera vertically
    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

    cv2.imshow('frame', frame)
    cv2.imshow('gray', gray)

    k = cv2.waitKey(30) & 0xff
    if k == 27: # press 'ESC' to quit
        break
cap.release()
cv2.destroyAllWindows()

是的，我尝试使用“import numpy”导入 numpy。

错误如下：

您需要安装 numpy==1.19.3 才能正常工作。所以你必须这样做：

1. pip uninstall numpy 卸载 numpy
2. pip install numpy==1.19.3 安装版本 1.19.3 的 numpy
