python-2.7 - 为什么 Python 线图显示 : Don't have an account? plot.ly

Question

其实我是python的新手。

当我尝试编译以下代码时:

import matplotlib.pyplot as plt

 import plotly.plotly as py
 # Learn about API authentication here: https://plot.ly/python/getting-started
 # Find your api_key here: https://plot.ly/settings/api

 x = [1,2,3,4]
 y = [3,4,8,6]

  plt.plot(x, 'o')
  plt.plot(y)
  fig = plt.gcf()

    plot_url = py.plot_mpl(fig, filename='mpl-line-scatter')

它显示以下消息，但不提供任何输出。 :

 mks@mks-H81M-S:~/Desktop/pythonPrograms$ python plot.py 
 Aw, snap! We don't have an account for ''. Want to try again? You can        authenticate with your email address or username. Sign in is not case    sensitive.

 Don't have an account? plot.ly

我不知道这是什么以及如何解决它。帮助。

就python的情节而言，我也很新。但是，在我看来，问题在于您正在导入 plotly.plotly。

从文档中引用

All methods in plotly.plotly will communicate with a Plotly Cloud or Plotly Enterprise. get_figure downloads a figure from plot.ly or Plotly Enterprise. You need to provide credentials to download figures: https://plot.ly/python/getting-started/

据我所知，您需要导入 plotly，然后使用此 link 介绍的后半部分中所述的函数。
希望这有帮助
