ModuleNotFoundError: No module named 'frontend'

问题

I have installed PymuPDF/fitz but upon running the sample code below, I am trying to extract images from PDF files

doc = fitz.open(pdf_path)
        for i in range(len(doc)):
            for img in doc.getPageImageList(i):
                xref = img[0]
                pix = fitz.Pixmap(doc, xref)
                if pix.n < 5:  # this is GRAY or RGB
                    pix.writePNG("p%s-%s.png" % (i, xref))
                else:  # CMYK: convert to RGB first
                    pix1 = fitz.Pixmap(fitz.csRGB, pix)
                    pix1.writePNG("p%s-%s.png" % (i, xref))
                    pix1 = None
                pix = None

it gives me following error, i have searched but there isn't single report of this kind of error, i have installed PyMuPDF, muPDF and fitz modules

Traceback (most recent call last):
  File "/home/waqar/PycharmProjects/predator/ExtractFileImage.py", line 1, in <module>

ModuleNotFoundError: No module named 'frontend'

回答1:

I've solved it by:

pip install PyMuPDF

回答2:

In file /home/waqar/anaconda3/envs/retinanet/lib/python3.6/site-packages/fitz/__init__.py

change

from frontend to from fitz.frontend
