This is already solved by myself but I put this question for someone else. I think this kind of problem is better as much as we can. and there doesn\'t seem be in SOF.
The solution is to downgrade PyQt5
.
pip install PyQt5==5.10.1
Collecting PyQt5==5.10.1

Requirement already satisfied: sip<4.20,>=4.19.4 in c:\anaconda3\lib\site-packages (from PyQt5==5.10.1) (4.19.8)
spyder 3.3.4 requires pyqtwebengine<5.13, which is not installed.
Installing collected packages: PyQt5
Found existing installation: PyQt5 5.12.1
Uninstalling PyQt5-5.12.1:
Successfully uninstalled PyQt5-5.12.1
Successfully installed PyQt5-5.10.1
This problem occurs because the PyQt5
I installed is beyond version as the version of spyder
.
