Answer 1

This is due to version differences of plotly.

To fix the same, you can:

• Upgrade plotly on Google Colab or Jupyter Notebook: !pip install --upgrade plotly
• Upgrade plotly on your system or Terminal: pip install --upgrade plotly

The Version 5.1.0 supports the required configuration.

To Install a specific version of plotly, you can use the command: pip install plotly==5.1.0
