我已经获得了使用matplotlib的python脚本，在运行脚本时它会打开窗口并显示图形 . 它在我的笔记本电脑上完美运行但是当我在AWS elasticbeanstalk上传文件时会发生此错误 . 我成功地使用我的笔记本电脑重现了这个错误

import matplotlib
matplotlib.use('agg')

引起的错误

File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/matplotlib/dates.py", line 1001, in viewlim_to_dt
.format(vmin))

这是该文件中的代码

def viewlim_to_dt(self):
    """
    Converts the view interval to datetime objects.
    """
    print(self.axis)
    vmin, vmax = self.axis.get_view_interval()
    if vmin > vmax:
        vmin, vmax = vmax, vmin
    if vmin < 1:
        raise ValueError('view limit minimum {} is less than 1 and '
                         'is an invalid Matplotlib date value. This '
                         'often happens if you pass a non-datetime '
                         'value to an axis that has datetime units'
                         .format(vmin))
    return num2date(vmin, self.tz), num2date(vmax, self.tz)

print（self.axis）显示此然后引发错误

XAxis(100.000000,373.620690)

当我删除matplotlib.use（'agg'）行时，print（self.axis）显示

XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis （200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000） ，110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000） ）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis （200.000000,110.000000）XAxis（200.00 0000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000， 110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000） XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（ 200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000， 110.000000）XAxis（200.000000,110.00000 0）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000） XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（ 200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000， 110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000） XAxis（200.000000,110.000000）XAxis（200.0 00000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000， 110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000）XAxis（200.000000,110.000000） XAxis（59.111111,106.555556）XAxis（59.111111,106.555556）XAxis（59.111111,106.555556）XAxis（59.111111,106.555556）XAxis（59.111111,106.555556）XAxis（59.111111,106.555556）XAxis（59.111111,106.555556）XAxis（59.111111,106.555556）XAxis（ 59.111111,106.555556）XAxis（59.111111,106.555556）XAxis（59.111111,106.555556）XAxis（59.111111,106.555556）XAxis（59.111111,106.555556）XAxis（59.111111,106.555556）XAxis（59.111111,106.555556）XAxis（59.111111,106.555556）XAxis（59.111111， 106.555556）XAxis（59.111111,106.555556）XAxis（59.11111 1,106.555556）XAxis（59.111111,106.555556）XAxis（225.000000,88.000000）XAxis（225.000000,88.000000）XAxis（225.000000,88.000000）XAxis（225.000000,88.000000）XAxis（225.000000,88.000000）XAxis（225.000000,88.000000）XAxis（225.000000,88.000000） XAxis（225.000000,88.000000）XAxis（225.000000,88.000000）XAxis（225.000000,88.000000）XAxis（225.000000,88.000000）XAxis（225.000000,88.000000）XAxis（225.000000,88.000000）XAxis（225.000000,88.000000）XAxis（225.000000,88.000000）XAxis（225.000000,88.000000）XAxis（225.000000,88.000000）XAxis（225.000000,88.000000）XAxis（225.000000,88.000000）XAxis（225.000000,88.000000）XAxis（ 225.000000,88.000000）XAxis（225.000000,88.000000）XAxis（225.000000,88.000000）XAxis（225.000000,88.000000）XAxis（122.930556,106.555556）XAxis（122.930556,106.555556）XAxis（122.930556,106.555556）XAxis（122.930556,106.555556）

    我自己解决了我的问题，在我的代码中注释掉了这一行

    plt.ion()

    正如我在我的问题中所说，该应用程序在开发环境中运行（在我的笔记本电脑中），但未在AWS服务器上运行 . 我希望，它可能对某人有所帮助 .
