Python 尝试导入tensorflow时出现UnicodeDecodeError

我见过其他人在tf中出现UnicodeDecors错误，但似乎总是这样，因为他们试图读取包含非拉丁字符的文件。我只是从导入tensorflow中得到这个错误，所以我不确定我的错误来自哪里

我使用的是Python 3.6.5，运行的是Windows 10，并通过pip安装了Tensorflow，所以它应该是最新的稳定版本

以下是我在尝试导入tensorflow时遇到的错误：

Traceback (most recent call last):
  File "C:\Users\jp11cy\AppData\Local\Programs\Python\Python36\lib\tokenize.py", line 390, in find_cookie
    line_string = line.decode('utf-8')
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa0 in position 10: invalid start byte

During handling of the above exception, another exception occurred:

通过重新安装Tensorflow解决了该问题
