从官网下载plotly4.6.0 在window7下安装 C:\Users\Administrator\Desktop>pip3 install plotly-4.6.0-py2.py3-none-any.whl
安装成功后import plotpy，提示ModuleNotFoundError: No module named ‘plotpy’
from plotly.plotly as py 提示The plotly.plotly module is deprecated,
please install the chart-studio package and use the
chart_studio.plotly module instead.
最后搜索资料，执行C:\Users\Administrator\Desktop>pip3 install -i https://pypi.tuna.tsinghua.edu.cn
/simple chart-studio 安装成功：
输入import chart_studio.plotly as py 可以啦
也就是说先下载chart-studio模块，pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple chart-studio 然后import plotly.plotly as py 改成 import chart_studio.plotly as py
