pyqt5中能用 seaborn吗

在PyQt5中可以使用seaborn，但需要先在PyQt5应用程序中加载Matplotlib模块。以下是一个简单的示例代码：

import sys
from PyQt5.QtWidgets import QApplication, QMainWindow, QSizePolicy, QWidget, QVBoxLayout
from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg as FigureCanvas
from matplotlib.figure import Figure
import seaborn as sns

class App(QMainWindow):
    def __init__(self):
        super().__init__()
        self.title = 'Seaborn in PyQt5'
        self.left = 0
        self.top = 0
        self.width = 600
        self.height = 400
        self.initUI()

    def initUI(self):
        self.setWindowTitle(self.title)
        self.setGeometry(self.left, self.top, self.width, self.height)
        self.createFigure()

    def createFigure(self):
        # Create the figure and axes objects
        fig = Figure()
        ax = fig.add_subplot(111)

        # Plot the data with seaborn
        sns.set()
        iris = sns.load_dataset('iris')
        sns.scatterplot(x='petal_length', y='petal_width', hue='species', data=iris, ax=ax)

        # Add the figure canvas to the PyQt5 application
        canvas = FigureCanvas(fig)
        canvas.setSizePolicy(QSizePolicy.Expanding, QSizePolicy.Expanding)

        # Add the figure canvas to a widget and set the layout
        widget = QWidget()
        layout = QVBoxLayout(widget)
        layout.addWidget(canvas)
        self.setCentralWidget(widget)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = App()
    ex.show()
    sys.exit(app.exec_())

在这个示例中，我们首先从Matplotlib中导入FigureCanvas，然后使用Seaborn绘制了一个散点图，并将其添加到了PyQt5应用程序中。注意，我们在绘图之前调用了`sns.set()`，以便使用Seaborn的默认样式。
