python ModuleNotFoundError: No module named ‘frontend‘

在做pdf转图片得时候，出现如下问题：

➜  OCR_table python pdf_to_image.py      
Traceback (most recent call last):
  File "pdf_to_image.py", line 1, in <module>
    import sys, fitz
  File "/home/eric/anaconda3/lib/python3.6/site-packages/fitz/__init__.py", line 1, in <module>
    from frontend import *
ModuleNotFoundError: No module named 'frontend'

解决办法：

pip install PyMuPDF
