Cell Execution feature for Notebooks

[Prahmodh-Raj1]

I'm currently unable to run the cells in the Notebook, that is being rendered in the React Application.

Link to the code: https://github.com/Prahmodh-Raj1/Jupyter-UI-Test

Terminal Error (on clicking the Run button of the cell): Requesting cell execution without any cell executor defined. Falling back to default execution.

Kindly help me resolve this issue. cc @echarles

Just tried and have a few questions/comments.

• Which packager are you using ? (yarn, npm...)
• You need to defined resolutions for yarn https://github.com/datalayer-examples/jupyter-react-cra-example/blob/5b3402da44d48ac27daeb3f9ed0bc5749f5c23a5/package.json#L41-L132

But it looks like you are building and running, so maybe just force reload your browser, it may help to solve the issue you reported.

I'm using npm to install the dependencies, and 'npm start' to start the cra application. @echarles

And is the current content of the App.tsx file enough to get the cells executing? Or should I need to add some other components too?

const App(()=>{

  const [tab, setTab] = useState(0);
  return (
    <>
      <Box>
        <Jupyter startDefaultKernel={true}>
              <Notebook
                path="Documents/Sample.ipynb"
                CellSidebar={CellSidebarRun}
              />
        </Jupyter>
      </Box>
    </>
  );
});

If you see the Notebook, that should be enough. Can you bumpt to 0.11.0? Any errors in the devtools console?

I tried updating to version 0.11.0, but i'm facing the following error when I execute the "npm install" command:

This is the error in the devtools console: @echarles

Requesting cell execution without any cell executor defined. Falling back to default execution.

@Prahmodh-Raj1 I have release jupyter-react 0.12.0 and pushed https://github.com/datalayer-examples/jupyter-react-cra-example/commit/3e0584724861edd7fc30188702fcfcd2a8330afc to update the example

On my env, the latest example works fine with both yarn and npm.

Can you try that?, hopefully it should fix the issue (which is linked to mixed non-compatible versions of jupyterlab, hence I have removed the constraints on the resolutions).

[Prahmodh-Raj1]

The cell execution is still failing in spite of updating the application with the latest commit: 3e05847.

The devtools console still produces the same error: Requesting cell execution without any cell executor defined. Falling back to default execution.

It would be great if you could please share another repo where the cell execution has been tested? @echarles

Thx again for tyring @Prahmodh-Raj1 The safest is to clone from zero https://github.com/datalayer-examples/jupyter-react-cra-example and use yarn to build/start (did a check also with npm and worked fine on my side).

If you still have the issue, this will probably come from non coherent juptyerlab packages in your node_modules (you would have to force them via resolutions).
