The only thing to check is the python version you install your packages for. 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. Hope this info helps Visal June 27, 2017, 12:32am 3. Installing the standalone doesn’t install those libraries or make them available outside the program.

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. If so, and if you’ve only installed the standalone program, you’ll need to install all the python libraries following the manual installation instructions. Another note I want to make is that I use Debian, but you did not specify your distribution. 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. 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.

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. 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. Then I tried to install python-qtpy, which did not work either. So I tried to install the package python-qt4, which happened to be already installed in my system. The first try to solve the problem was installing the packages pyqt4-dev-tools and pyqt4.qsci-dev, which did not solve the problem. 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 I have a Debian system, so I used apt to install all the packages I wanted to install.

Testing the import statement outside of the file gave the message “DLL load failed: %1 is not a valid Win32 application.” That's what suggests the DLL mismatch, and also answers why it was trying to fall back to PyQt4.I've tried to reproduce your error and in fact I succeeded in doing that. # fell through, tried PyQt5, failed fall back to PyQt4 if QT_API = QT_API_PYQT5:įrom PyQt5 import QtCore, QtGui, QtWidgets However, when it gets to the lines below, the import fails so it tries to fall back to PyQt4, which isn’t installed with Anaconda, and thus issues the error. For most of the time through this module, it’s trying to work with PyQt5, as that’s what it finds in the environment. To work through this, I stepped through qt_compat.py where the error originates. The short answer is that I uninstalled Anaconda 64-bit and installed the 32-bit version instead. I ran into a similar thing and found that the problem was having a 64-bit Anaconda installation that couldn't load the PyPt5 DLLs that were perhaps 32-bit.
