I've installed Jupyter Notebook on AWS (Ubuntu 14.04). The notebook runs, however, does not connect to kernels:
The shell output:
[I 15:00:22.857 NotebookApp] Kernel interrupted: 805928a8-674d-458f-b990-d86bd3c26711 [I 15:01:24.459 NotebookApp] Saving file at /Notebooks/R Example.ipynb [I 15:01:37.533 NotebookApp] Creating new notebook in /Notebooks [W 15:01:38.626 NotebookApp] 404 GET /nbextensions/nbpresent/js/nbpresent.deps.min.js.js (188.8.131.52) 1.86ms referer=https://184.108.40.206:8888/notebooks/Notebooks/Untitled.ipynb?kernel_name=python3 [I 15:01:38.656 NotebookApp] Kernel started: 0a9a882e-1e55-4913-8640-8213c1aae88f [I 15:01:58.721 NotebookApp] Kernel restarted: 0a9a882e-1e55-4913-8640-8213c1aae88f
What may the cause?
