Question

我使用pip install pyqt5安装了PyQt5。安装成功。 matplotlib的pip安装表示已满足所有要求。当我运行matplotlib时，我收到了流动的错误：

Traceback (most recent call last):
  File "", line 6, in <module>
    import matplotlib.pyplot as plt
  File "C:\Program Files\Anaconda3\lib\site-packages\matplotlib\pyplot.py", line 115, in <module>
    _backend_mod, new_figure_manager, draw_if_interactive, _show = pylab_setup()

    from PyQt5 import QtCore, QtGui, QtWidgets
ImportError: DLL load failed: %1 is not a valid Win32 application.

搜索表明已安装的软件包可能是不同的位版本（例如，当我需要54位时为32位）。我该如何解决这个问题？

如果您不同时使用pyqt和matplotlib，请尝试安装conda并将其环境分开。我遇到了这样的问题，我做到了。我不记得确切是什么，但我记得qt 5.9和qt 5.13库发生冲突

PyQt5与PyCharm中的matplotlib冲突
