I use PyCharm 2019.1.2 Professional with installed packages about Jupyter on Windows 10 Pro ver 1903.
Then I open 3 files Index.ipynb and s3_bubble-charts.ipynb and SequentialStructure.ipynb.
This file is open without any problem.
I double click to open it but nothing happen.
This file is opened with blank page and show no code inside it.
Please help me solve this problem
Here is the link to download these three files.
