python-3.x - 情节图不可见

Question

我在 jupyter-lab 中的绘图有问题。主要是情节。当我执行代码时，不显示绘图。这个问题我该怎么办？如何使情节可见？

示例代码：

import plotly.graph_objects as go

from datetime import datetime

open_data = [33.0, 33.3, 33.5, 33.0, 34.1]
high_data = [33.1, 33.3, 33.6, 33.2, 34.8]
low_data = [32.7, 32.7, 32.8, 32.6, 32.8]
close_data = [33.0, 32.9, 33.3, 33.1, 33.1]
dates = [datetime(year=2013, month=10, day=10),
         datetime(year=2013, month=11, day=10),
         datetime(year=2013, month=12, day=10),
         datetime(year=2014, month=1, day=10),
         datetime(year=2014, month=2, day=10)]

fig = go.Figure(data=[go.Ohlc(x=dates,
                          open=open_data, high=high_data,
                          low=low_data, close=close_data)])
fig.show()

和输出屏幕：
