Hi @cibic89,
Are you working in the classic jupyter notebook, JupyterLab, or something else? If you’re in the classic notebook then try updating it to the newest version of the notebook package. If you’re in JupyterLab you need to install the @jupyterlab/plotly-extension JupyterLab extension (follow the instructions at https://github.com/plotly/plotly.py#jupyterlab-support-python-35).
