No module named ‘PyQt4.sip’
I’ve tried to reproduce your error and in fact I succeeded in doing that. I have a Debian system, so I used apt to install all the packages I wanted to install.
I tried to run in an interactive python environment (sorry for the bad terminology, I’m not proficient in python: I used it only a few times to solve very simple math problems) the code
The first try to solve the problem was installing the packages pyqt4-dev-tools and pyqt4.qsci-dev , which did not solve the problem. So I tried to install the package python-qt4 , which happened to be already installed in my system. Then I tried to install python-qtpy , which did not work either. Then I stumbled upon this question on StackOverflow, which gave me the idea that I was using the wrong python version (by default I use python 3.7), so I tried to run the aforementioned command in a python 2.7 and it worked.
Now, because I was disappointed by the lack of support of python 3, I tried to look for some other packages about qt and python 3 and I found python3-qtpy . I installed it and the command. still did not work. However, while it was installing, I noticed that it was installing the version 3 of the qt libraries, so I tried to run, in the interactive python 3 environment, from PyQt5.QtGui import * and it worked.
Some notes: I saw that it also installed python3-sip together with python3-qtpy and that I’ve already installed on my system the package python-sip ; not sure if this helps. Another note I want to make is that I use Debian, but you did not specify your distribution. This wouldn’t in general be a problem as python should not be dependent on the OS it’s running on, however, having used apt and the Debian repos to install all the required dependencies might be an influencing variable in the solution of the problem. As I mentioned before, I rarely use python, but I know you can use pip to install new «packages» or the StackOverflow answer uses brew. The only thing to check is the python version you install your packages for. EDIT: If you need it, have a look at python qtpy version 4 on pip and python qtpy version 5 on pip
Now, I tried to be as detailed as possible in explaining what I did to solve the import problem, but if you have some more question, feel free to add a comment below.
PyQt4, Centos7 and Python3- ImportError: No module named ‘PyQt4’
I’m working on Centos7 and using Python 3.3.2. I’m trying to run a Python script that uses PyQt4 modules but I’m getting this error:
ImportError: No module named 'PyQt4' The script doesn’t yet have it’s full functionality but I’m just trying to ensure it runs and can access the correct modules etc at this early stage as I’m new to python. Here is the script so far:

How can I correct this so that it works with Python 3.3.2? I’ve tried yum install python-pyqt4 but on Centos there doesn’t seem to be a package available. Any ideas? Thanks
Python 3.8 pytest-qt ModuleNotFoundError: No module named ‘PyQt4’
I have created my project on Linux mint 19 with python 3.6 installed. I used pytest in conjunction with pytest-qt to test my app which is a PyQt5 program. Then, I’ve updated to Linux mint 20. However python 3.8 is installed there instead of 3.6. I don’t know whether it’s related or not but now I can’t run my test suite anymore, when I type pytest in terminal it gives me the following output:

I have pytest and pytest-qt both installed. The program itself works properly. Thanks.
