问题描述

我已经得到了使用matplotlib的python脚本，在运行脚本时它将打开窗口并显示图形.它可以在我的笔记本电脑上正常工作.但是，当我在AWS Elasticbeanstalk上上传文件时会发生此错误.我通过使用

I've been given the python script where matplotlib is used , when running the script it opens the window and display graph. its working perfectly on my laptop. But this error occurs when I upload the file on AWS elasticbeanstalk. I successfully reproduce this error in my laptop by using

import matplotlib
matplotlib.use('agg')

引发的错误

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)显示此内容，然后引发错误

print(self.axis) shows this and then raises error

XAxis(100.000000,373.620690)

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

when I remove the line matplotlib.use('agg') , print(self.axis) shows

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(200.000000,110.000000)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(200.000000,110.000000)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(200.000000,110.000000)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(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(59.111111,106.555556)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)

Can anyone helps me out, I don't know what's going on. I'm using python3 here is my full import

# -*- coding: utf-8 -*-
import numpy as np
import matplotlib
matplotlib.use('agg')
import matplotlib.pyplot as plt
import datetime
from matplotlib.dates import DateFormatter
from matplotlib.dates import HourLocator

这是完整的错误跟踪

推荐答案

我已经解决了自己的问题，方法是在代码中将此行注释掉

I've resolved my issue by myself, by comment-out this line in my code

plt.ion()

正如我在问题中所说，该应用程序正在开发环境中(在我的笔记本电脑中)运行，但未在AWS服务器上运行.希望对您有所帮助.

as I said in my question, the app was running in development env (in my laptop) but not running on the AWS server. I hope, it may help someone.

这篇关于ValueError:视图限制最小值0.0小于1，并且是无效的Matplotlib日期值的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
