For anyone getting this error when trying to open the deigner: "this application failed to start because no qt platform plugin could be initialized" I solved it by going into the plugins folder and copying a folder called "platforms", I then pasted the folder where the designer.exe is located.

Another way of finding where Python is installed on Windows is just typing the command in CMD: "where python" and it will show the installed locations on your PC!

[@till-louiswinters3484]

When you have no idea where you can find your python folder, open cmd/terminal and write "where python". That will show you the install path on your computer.

Using Python 3.10.4, I found that PyQt5-tools had an error when installing. PyQt5 was fine. Nothing seemed to resolve this until I removed Python and installed 3.9.10 which allowed me to install both PyQt5 and PyQt5-tools. The Designer and pyuic5 both worked perfectly. Great tutorial! Thank you Tim.

[@cnfnbcn3227]

That's because PyQt works only with Python 3.9 and lower

[@guireis5389]

For those who are experiencing this error: "'pyuic5' is not recognized as an internal or external command, operable program or batch file. " This is because your pyuic5.exe is not in PATH. Probably your pyhton script folder is not in PATH, even though you put the option "add to Path" when you were installing Python. This happened to me, my Python folders are scattered around and I don't even know why. There are two methods of resolving: 01 - (What I did) The folder he shows that has all the files that pip installed, I added to PATH. (So much so that when you install a new library, you will no longer see that warning suggesting to add it to the path as the entire folder is already there.) There are already tutorials on the internet, it's very simple 02 - Instead of typing "pyuic5", you write the location where "pyuic5.exe" is. It's more complicated, but it also works. Like if I helped you :)

Thanks for the awesome video! When I run pyuic5 from my folder with the test.ui file, I was giving me a 'pyuic5' is not recognized as an internal or external command So then I went and found the pyuic5 application, from the scripts folder, copied it, and pasted it into the folder with the test.ui file, and it worked. Is this due to the scripts folder not being on PATH? I still don't really understand how to add folders to path~ thank you!!

[@Xanderioz]

for some reason I do not have pyuic5 in scripts folder either, any solution?

[@goldenslingshot6251]

look i had this probleme but there's a way to solv it Suppose you have saved your file from Qt Designer as dialog.ui. Then you can create another file, say main.py, with the following contents: from PyQt5 import uic from PyQt5.QtWidgets import QApplication Form, Window = uic.loadUiType("dialog.ui") app = QApplication([]) window = Window() form = Form() form.setupUi(window) window.show() app.exec_() it actualy worked you can try it

I recommend PySide (now 6, for Qt6), it is very alike PyQt, but more up to date, and based on LGPL license - you don't need to publish source for your commercial code... BTW, Qt Designer comes as part of PySide, with no additional library to install.

[@mr.m2193]

Hey, the tutorials are done really well! But I have a little problem, not critical one, but still annoying. So, whenever I run a python file with Qt script in it, it opens the app and another terminal that spits out this message: Warning: QT_DEVICE_PIXEL_RATIO is deprecated. Instead use: QT_AUTO_SCREEN_SCALE_FACTOR to enable platform plugin controlled per-screen factors. QT_SCREEN_SCALE_FACTORS to set per-screen factors. QT_SCALE_FACTOR to set the application global scale factor. Can't seem to find any way of fixing it. Could use a helping hand, or you could put this in your next video, if you want. Have a great day!
