FileNotFoundError in demo_prepare.ipynb

[vncntprvst]

Bug Report

Description

The repo's Instructions say: "We recommend you start by navigating to the notebooks directory on the left panel and go through the demo_prepare.ipynb".
When executing code cell 5 in that notebook

populate_settings = {"display_progress": True}

ephys.EphysRecording.populate(**populate_settings)

a FileNotFoundError occurs.

Reproducibility

Repository environment created with Dev Containers extension.
Navigate to demo_prepare.ipynb notebook, select kernel and execute code.
Error stack:

Output exceeds the [size limit](command:workbench.action.openSettings?[). Open the full output data [in a text editor](command:workbench.action.openLargeOutput?5cae5363-0515-4d6b-9fe4-f0979c9a6448)

Expected Behavior

The data should be downloaded first then used to populate the database.

Thanks for the report @vncntprvst.

• We recommend using GitHub Codespaces for tutorials which will have the example data automatically mounted.

• We will be adding a tutorial.ipynb notebook shortly that provides a more comprehensive overview of the Element and Workflow.

• Once you are ready to run the workflow on your data, you can set up the workflow locally.
