Error starting cluster

[D-marina]

Hello,

I tried to use several engines in jupyter and I followed this steps:

($ is my prompt) 1.- $jupyter serverextension enable --py ipyparallel 2.- $jupyter nbextension install --py ipyparallel 3.- $jupyter nbextension enable --py ipyparallel 4.- $jupyter nbextension enable ipyparallel --py

then I opened a browser, I clicked in IPython Clusters's tab, selected 2 engines and I pressed start. But in status I got "error starting cluster". I don't know if this issue is solved but I can't solve this problem.

In the console, I get the following:

Enabling: ipyparallel.nbextension
- Writing config: /home/daniel/.jupyter
    - Validating...
      ipyparallel.nbextension  OK

    To initialize this nbextension in the browser every time the notebook (or other app) loads:

          jupyter nbextension enable ipyparallel --py

This seems to be an issue with IPython Clusters, not jupyter-drive issue. Could you open an issue in https://github.com/ipython/ipyparallel?

Done, thank you very much.
