Call Python from matlab, error related to Matplotlib.pyplot

Hi, everyone,

I am calling a Python script from Matlab, if the program included code likes 'import matplotlib.backends.qt_editor.figureoptions as figureoptions, or import matplotlib.pyplot as plt', an error 'Python Error: AttributeError: module 'matplotlib' has no attribute 'pyplot'' will was occured. Please help me to fin this problem, thank you.

import numpy
import skimage
import matplotlib.pyplot as plt
from skimage import io
from skimage.morphology import watershed

def imgread():
    imgpath='D:/PROJECT/CoreModelingV1.2/Pore_Extr_Sim/Img4codeDev_S35'
    imgtype='\*.png'
    imgname=imgpath+imgtype
    print('the file is: ',imgname)
    img=skimage.io.imread_collection(imgname)
    imdata=img.concatenate()
    # imdata=imdata[:,300:500,300:500]
    # imdata=imdata[:,380:480,300:400]

    imdata=imdata==0
    plt.figure(figsize=[10, 10])
    plt.imshow(imdata[0], origin='upper')
    plt.show()
    return imdata
   

py.test5.imgread

the file is: D:/PROJECT/CoreModelingV1.2/Pore_Extr_Sim/Img4codeDev_S35\*.png

Error using test5>imgread (line 18)

Python Error: AttributeError: module 'matplotlib' has no attribute 'pyplot'

Hello,

This error seems to be a Python error and not a MATLAB one. Does the script throw the same error when executed through command line?

MATLAB and matplotlib both ship with Qt graphics libraries. Try changing matplotlib's graphics backend to a different library to avoid conflicts. Change

import matplotlib.pyplot as plt

to

import matplotlib
matplotlib.use('WXAgg')
import matplotlib.pyplot as plt
