无法从python scrip登录到plotly

Question

我是Plotly的新手，正在尝试从Plotly网站上提供的文档创建基本图形，但在Spyder（3.3.1）中运行脚本时，会收到错误消息“PlotlyError:登录失败”。我正在使用.credentials文件中的用户名和api密钥，因此我不确定下一步该去哪里。任何帮助都将不胜感激。你知道吗

import plotly 
import plotly.plotly as py
import plotly.graph_objs as go

#get plotly credentials and store in list
plty_creds = list(py.get_credentials().values())
plotly.tools.set_credentials_file(username = plty_creds[0],
                                  api_key = plty_creds[1])

trace0 = go.Scatter(
    x=[1, 2, 3, 4],
    y=[10, 15, 13, 17]
)
trace1 = go.Scatter(
    x=[1, 2, 3, 4],
    y=[16, 5, 11, 9]
)
data = [trace0, trace1]

py.sign_in(username = plty_creds[0], api_key = plty_creds[1])

py.plot(data, filename = 'basic-line', auto_open = True)

Answer 1

而不是这个

plotly.tools.set_credentials_file(username = plty_creds[0], api_key = plty_creds[2])

试试这个

plotly.tools.set_credentials_file(username = plty_creds[0], api_key = plty_creds[1])
