问题描述
我使用pip安装了matplotlib lib,但是当我运行此代码时,它给了我这个错误:
I have matplotlib lib installed using pip but when I run this code it gives me this error:
shar@shar-Lenovo-G50-30 ~ $ python3 opencv.py
Traceback (most recent call last):
File "opencv.py", line 3, in <module>
from matplotlib import pyplot as plt
ImportError: cannot import name 'pyplot'
我的代码是:
import numpy as np
import cv2
from matplotlib import pyplot as plt
img1 = cv2.imread('/home/shar/home.jpg',0) # queryImage
img2 = cv2.imread('/home/shar/home2.jpg',0) # trainImage
# Initiate SIFT detector
orb = cv2.ORB()
# find the keypoints and descriptors with SIFT
kp1, des1 = orb.detectAndCompute(img1,None)
kp2, des2 = orb.detectAndCompute(img2,None)
# create BFMatcher object
bf = cv2.BFMatcher(cv2.NORM_HAMMING, crossCheck=True)
# Match descriptors.
matches = bf.match(des1,des2)
# Sort them in the order of their distance.
matches = sorted(matches, key = lambda x:x.distance)
# Draw first 10 matches.
img3 = cv2.drawMatches(img1,kp1,img2,kp2,matches[:10], flags=2)
plt.imshow(img3),plt.show()
我还尝试从源代码安装matplotlib,但这仍然给我错误.
I also tried to install matplotlib from source and that still give me the error.
推荐答案
请确保您没有创建的任何文件名matplotlib.py(如果有的话),然后重命名或删除该文件.它对我有用
Make sure you don't have any file names matplotlib.py that you have created if any then rename or delete that file. It worked for me
