Plotly AttributeError: 'dict' object has no attribute 'write_html'

Question

我正在尝试将 Plotly 图导出为 HTML，各种文档和 SO 线程建议在图形对象（字典）上失败的方法。任何帮助表示赞赏。最后几行是导致错误的行。该图在交互式 Python window 中绘制得很好，但我无法保存到 html。

代码：

fig = dict(data=[data_trace], layout=layout)
# this plots the figure, but doesn't create a file
iplot(fig, filename='sankey.html',validate=False)

# this returns an error
fig.write_html("sankey.html")

错误：

AttributeError: 'dict' object has no attribute 'write_html'

Answer 1

只需更改：

fig = dict(data=[data_trace], layout=layout)

至：

fig = go.Figure(dict(data=[data_trace], layout=layout))

你应该可以开始了。

在我的工作目录中生成以下内容：

Plotly AttributeError: 'dict' object has no attribute 'write_html'

Plotly AttributeError: 'dict' object has no attribute 'write_html'

python
