AttributeError can't get attribute on module pydevd

Hi:

I encounter a problem and the error shows as following:

Exception in thread Thread-16:
Traceback (most recent call last):
File "D:\ProgramData\Anaconda3_4.4.0\lib\threading.py", line 916, in _bootstrap_inner

AttributeError: Can't get attribute 'Entry1' on <module 'pydevd' from 'D:\\Program Files\\JetBrains\\PyCharm Community Edition 2017.2.2\\helpers\\pydev\\pydevd.py'>

I tried the same code in idle and it works fine. I am using pycharm community edition 2017.2.3

Any help please?
