How do I resolve "No module named 'frontend'" error message?

Question

I have installed PymuPDF/fitz because am trying to extract images from PDF files. However, upon running the code below, I am seeing No module named 'frontend'.

    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 

I have searched but there isn't single report of this kind of error. I have installed PyMuPDF, muPDF and fitz modules

Here is the error in full:

    Traceback (most recent call last):       File "/home/waqar/PycharmProjects/predator/ExtractFileImage.py", line 1, in <module>         import fitz       File "/home/waqar/anaconda3/envs/retinanet/lib/python3.6/site-packages/fitz/__init__.py", line 1, in <module>         from frontend import *     ModuleNotFoundError: No module named 'frontend'
