ImportError: The _plotly_future_ module must be imported before the plotly module

Question

我尝试在 Python 中重现制作 plotly 情节的示例，该情节作为第一个示例 here: "Subplots in Python" 发布。我在 Jupyter notebook 上工作，plotly 版本：3.10.0，Python 版本：3.6.3.

在运行那个例子之后：

from plotly.subplots import make_subplots
import plotly.graph_objs as go
from plotly.offline import download_plotlyjs, init_notebook_mode, plot, iplot

## Allow to generate plotly plots inline in notebook
init_notebook_mode(connected=True)

fig = make_subplots(rows=1, cols=2)
fig.add_trace(go.Scatter(x=[1, 2, 3], y=[4, 5, 6]), row=1, col=1)
fig.add_trace(go.Scatter(x=[20, 30, 40], y=[50, 60, 70]), row=1, col=2)
fig.update_layout(height=600, width=800, title_text="Subplots")
iplot(fig)

我得到 ValueError:

ValueError: 
plotly.subplots.make_subplots may only be used in the
v4_subplots _plotly_future_ mode.  To try it out, run
>>> from _plotly_future_ import v4_subplots
before importing plotly.

然后我在导入的最顶部添加了 from _plotly_future_ import v4_subplots。我清理了输出，使用 %restet 清理了所有变量，甚至刷新了笔记本，但是带有标题的代码：

from _plotly_future_ import v4_subplots 
from plotly.subplots import make_subplots 
import plotly.graph_objs as go from plotly.offline import download_plotlyjs, 
init_notebook_mode, plot, iplot
# (...)

结果现在在 ImportError:

ImportError: The _plotly_future_ module must be imported before the plotly module

如何解决？

Answer 1

您可能需要重新启动内核：仅刷新笔记本是不够的。

也就是说，第 4 版现已发布，所以您最好的选择是升级 :)
