Question

我正在尝试运行代码来获取交互式GUI。但是，在尝试使用％matplotlib qt时出现以下错误：所以，我尝试使用％matplotlib qt5，问题仍然存在。我检查了后端文件夹。我好像有backend_qt4agg和backend_qt5agg。我使用的是Conda 4.3.30，Python 3.6.3和Matplotlib 2.1.0版。

任何帮助将不胜感激。谢谢！ ModuleNotFoundError：没有名为＆＃39; PyQt4＆＃39;

＆＃13;

显然，PyQt4已经在anaconda 3中逐步淘汰。如果是这样，我需要调用什么才能让交互式matplot lib使用与此类似的代码：

    import pandas as pd
    from pandas import DataFrame
    import matplotlib.pyplot as plt
    from mpl_toolkits.mplot3d import Axes3D
    T_P1_G1_Th = plt.figure().gca(projection='3d')
    T_P1_G1_Th.scatter(df['Drehzahl'], df['Moment'], df['T_P1_G1_Th'])
    T_P1_G1_Th.set_xlabel('Engine Speed')
    T_P1_G1_Th.set_ylabel('Torque')
    T_P1_G1_Th.set_zlabel('P1_Temp_thrust side')
    plt.show()

谢谢！

尽管后端文件夹中存在文件，但未找到PyQt4。
