Nexus tutorial failing

[adrien-berchet]

Hello,

In the Nexus tutorial, when I try to run the one_cell_minds notebook, I get an error when I execute the following cell:

forge = KnowledgeGraphForge("https://raw.githubusercontent.com/BlueBrain/nexus/ef830192d4e7bb95f9351c4bdab7b0114c27e2f0/docs/src/main/paradox/docs/getting-started/notebooks/forge.yml",

KeyError: 'base'

I think I followed the tutorial properly. Any clue?

Thanks!

Hi @adrien-berchet ,

Can you tell me the value of bucket, i.e f"{ORG}/{PROJECT}" ?

For info:

Set ORG to be "github-users" => ORG = "github-users" Set PROJECT to be the automatically created project name (this name is your github account user name) when you logged into the Nexus sandbox instance.

You can look at your created project in => https://sandbox.bluebrainnexus.io/web/admin/github-users

Hello @MFSY Indeed I did not see I had to set the PROJECT value, sorry about this... Thanks for your help!
