ModuleNotFoundError: No module named 'frontend'

[cwj]

操作步骤：
pip insatll fitz 安装未报错

import fitz
报错 ImportError: No module named 'frontend'
请问大概是什么原因呢？

环境是python3.6版本。

具体信息如下：
(tensorflow) [root@tensorflow01 ~]# python3.6
Python 3.6.8 |Anaconda, Inc.| (default, Dec 30 2018, 01:22:34)
[GCC 7.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

import fitz
Traceback (most recent call last):

from frontend import *
