when I use the script the window flashes and then disappears, so I just want to know how to make it stay for a long time? Thanks very much! you can get this python package form 

from spectral import *
img = open_image('92AV3C.lan')
view = imshow(img, (29, 19, 9))


def imshow(data=None, bands=None, classes=None, source=None, colors=None,
       figsize=None, fignum=None, title=None, **kwargs):
    import matplotlib.pyplot as plt
    from spectral import settings
    from .graphics import get_rgb

    set_mpl_interactive()

    view = ImageView()
    if data is not None:
        view.set_data(data, bands, **kwargs)
    if classes is not None:
        view.set_classes(classes, colors, **kwargs)
    if source is not None:
        view.set_source(source)
    elif data is not None and len(data.shape) == 3 and data.shape[2] > 3:
        view.set_source(data)
    if fignum is not None or figsize is not None:
        fig = plt.figure(num=fignum, figsize=figsize)
        view.show(fignum=fig.number)
    else:
        view.show()

    if title is not None:
        view.set_title(title)
    return view

I use PyCharm2019 and python3.8. After add two lines, it works. import matplotlib.pyplot as plt plt.pause(10)

It flashes because the program execution finishes, which closes the GUI.

The common approach is to call plt.pause(<expected pause in seconds>) after calling view.show.
