我尝试使用cufflinks绘制一个 Dataframe ，但df.iplot()不起作用--它在10秒后不返回。vscode + jupyter扩展名。plotly工作正常。有什么建议我做错了什么吗？

import cufflinks as cf
cf.set_config_file(world_readable=True,theme='pearl')
df = cf.datagen.lines()
df.head()

df.iplot() # does not return

我有plotly和袖扣安装如下：

conda install -c plotly plotly=5.10.0 
conda install "notebook>=5.3" "ipywidgets>=7.5" 
conda install -c conda-forge cufflinks-py

# conda list | grep -e plotly -e cufflinks
# cufflinks-py              0.17.3                     py_0    conda-forge
# plotly                    5.10.0                     py_0    plotly
# python-cufflinks          0.17.3                     py_0    conda-forge
