From 0bc34a5bc96c664242852f9cfe323b72edc61a60 Mon Sep 17 00:00:00 2001 From: CrystalRays Date: Wed, 15 Dec 2021 12:41:10 +0800 Subject: [PATCH] Fix TypeError at line 459 in toolbox/ui.py when both PySide6(PyQt6) and PyQt5 installed (#255) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ### Error Info Screenshot ![](https://cdn.jsdelivr.net/gh/CrystalRays/CDN@main/img/16389623959301638962395845.png) ### Error Reason Matplotlib.backends.qt_compat.py decide the version of qt library according to sys.modules firstly, os.environ secondly and the sequence of PyQt6, PySide6, PyQt5, PySide 2 and etc finally. Import PyQt5 after matplotlib make that there is no PyQt5 in sys.modules so that it choose PyQt6 or PySide6 before PyQt5 if it installed. 因为Matplotlib.backends.qt_compat.py优先根据导入的库决定要使用的Python Qt的库，如果没有导入则根据环境变量PYQT_APT决定，再不济就按照PyQt6, PySide6, PyQt5, PySide 2的顺序导入已经安装的库。因为ui.py先导入matplotlib而不是PYQT5导致matplotlib在导入的库里找不到Qt的库，又没有指定环境变量，然后用户安装了Qt6的库的话就导入Qt6的库去了 --- toolbox/ui.py | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/toolbox/ui.py b/toolbox/ui.py index 6c33418..34f8efe 100644 --- a/toolbox/ui.py +++ b/toolbox/ui.py @@ -1,9 +1,9 @@ -import matplotlib.pyplot as plt -from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg as FigureCanvas -from matplotlib.figure import Figure from PyQt5.QtCore import Qt, QStringListModel from PyQt5 import QtGui from PyQt5.QtWidgets import * +import matplotlib.pyplot as plt +from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg as FigureCanvas +from matplotlib.figure import Figure from encoder.inference import plot_embedding_as_heatmap from toolbox.utterance import Utterance from pathlib import Path
