Hello I’m trying to do the Dash Tutorial, specially this one [https://dash.plot.ly/getting-started](https://dash.plot.ly/getting-started) but can’t run the app. I can’t run the app on jupyter lab that always give this error. UnsupportedOperation: not writable I found some answers but no one works for me, I tried downgrading the flask version and it doesn’t works. If anybody can help me I will appreciate it so much. Thank you, M ---

Welcome aboard @mripani! If you’re not using a Windows machine, this Dash JupyterLab extension might help: [https://github.com/plotly/jupyterlab-dash](https://github.com/plotly/jupyterlab-dash) Otherwise I would try running your first Dash app from another IDE, such as VSCode. Hope that this helps! ---
