Background on the question: This is a previous PyQt project I am working on and trying to start the GUI. I have set an Anaconda Environment with Python 2.7 and used PyQt4. The Error is :-
File "gui/gui.py", line 26, in <module>
from qtpy.QtCore import (Qt, QFileSystemWatcher, QSettings, pyqtSignal)
ImportError: cannot import name pyqtSignal
Code :-
enter #import qt
from qtpy import QtCore, QtWidgets, QtGui, PYQT4 #changed from PYQT5
from qtpy.QtCore import (Qt, QFileSystemWatcher, QSettings, pyqtSignal)
Even after trying to setup the environment and other aspects to the best of my ability, I am unable to pinpoint why this error still pops up.Tried on Mac, it errors out similarly even on Ubuntu. Does anyone have an idea how to tackle this?
You're using qtpy
rather than PyQt4
directly. According to Don't delete QtCore.{pyqtSignal,pyqtSlot,pyqtProperty} · Issue #76 · spyder-ide/qtpy · GitHub, they deliberately ditched PyQt
-specific names like pyqtSignal
and instead rename them upon import to generic names like Signal
for uniformity. They comment that these names follow Qt5
's naming scheme.
So you should just
from qtpy.QtCore import Qt, QFileSystemWatcher, QSettings, Signal
and rename all pyqtSignal
to Signal
elsewhere in your code.
