Is there an upgrade for the class PrettyWidget(QtGui.QWidget): packages

Python Help
,
1

Hi all, I am running an example in colab but when I get to this code I’m getting an error!

class PrettyWidget(QtGui.QWidget):
^
SyntaxError: unexpected EOF while parsing,

As a solution, I installed the specific packages for PyQt5 and the QtGui modules as PyQt4 is not working but that was futile!

I tried this solution Ui_Widget(QtWidgets.QWidget) based on my google search but that did not work also!

can some one guide with this procedure, please? My limited understanding is hindering my processing forward.

thank you in advance for acknowledging my digital presence!

Is this the last line of the file/example?

class PrettyWidget(QtGui.QWidget):

If so, the error is that the file is truncated. That’s what the EOF (End Of File) error is telling you.

HI DB,

I tried your solution by adding all of the code, I tried thisbefore but still the error persist! so I was trying to figure out line by line where the error is! please see the code for the demo taken from the link at very top of ALL OF The CODE!

I checked the packages in the foldder based on the error and the file is there but I am not sure why this error persist!

Can you guide me with this error, please so that I can understand what I am doing wrong? thanx in advance!

OK. The error is now this:

AttributeError: module ‘PyQt5.QtGui’ has no attribute ‘QWidget’

You identified this as an error in another file. The problem is that QWidget is part of the PyQt5.QtWidgets module in PyQt 5.

A lot of the code looks like it is written to use PyQt 4, so you are going to encounter more errors like this one. Look for lines with QtGui and check to see if the classes they use are now in the QtWidgets module.

7

Hi DB, it seems that is was written to encompass the PyQt4 for the demo file via the link but the author mentioned that it may not work with the PyQt4 and I can try the PyQt5!??!

What I find strange is that when I apply the PyQt4 the packages are not available and is stated as missing!

Really trying to understand this, it’s a pain especially when I cannot see the error! Thanx for responding pal! standing by for your response!!

YOUR Last Instruction;
" Look for lines with QtGui and check to see if the classes they use are now in the QtWidgets module"

ME: How? Can you guide me, please?
is there a show packages statement that I am not aware of?
let me know please!

Please see the errors is;

ModuleNotFoundError Traceback (most recent call last)
in ()
47 import os, sys
48 import pickle
—> 49 from PyQt4 import QtGui # If PyQt4 is not working in your case, you can try PyQt5
50 import qtwidgets
51 seed = 7

ModuleNotFoundError: No module named ‘PyQt4’

NOTE: If your import is failing due to a missing package, you can
manually install dependencies using either !pip or !apt.

“Open Examples” button below.

It seems that you don’t have PyQt 4 installed because it wasn’t working and are trying to use PyQt 5 instead. If so, just focus on fixing the errors related to QtGui and forget about PyQt 4. It will probably help you in the long run because PyQt 4 is now very old and code that uses it will need to be updated.

The program you show in one of your earlier replies contains lines like this one:

In PyQt 5, QPushButton is not part of the QtGui module. You need to find lines like this and fix them to use QtWidgets instead.

Ok no probs will work on this now! thanx for redirecting me! I will notify you concerning the upgrades!

thanx once more DB, really appreciate this!

10

Ha Ha Ha! David, guess what?

The entire thing continually crashes when applying the changes you suggested lolz, but it did run by the way without any errors prompts, so coo-do’s for that pal!!!

I am now searching to see where I can view the details or logs on why this occurred!

Hey Mat, can you please guide me on how you handled this issue? I am going through the same errors with the same code. duafatimaquresh@gmail.com
