Why is PyQt5 and sip not compatible?

Question

Python

Good afternoon.
There is an error:

Traceback (most recent call last):
  File "path/to/Main.py", line 5, in <module>
    from PyQt5.QtGui import QPixmap, QIcon
RuntimeError: the sip module implements API v11.0 to v11.3 but the *** module requires API v12.2

I looked for a solution, found a couple of ways:
1. conda upgrade sip (etc.)
Doesn't work.
2. Install PyQt and python under the same version of .
The question is which version of PyQt to use for python 3.4.5
Please help.
Thanks in advance.
