charset=us-ascii Content-Disposition: inline Hello: I've been trying to set up a Jupyter environment with the Guix kernel inside a guix environment using: `guix environment --ad-hoc guix-jupyter jupyter -- jupyter notebook`. Jupyter starts up fine, but when I create an empty notebook with the Guix kernel it spams Nudge messages in the console, followed by a crash: ``` [W 16:25:40.117 NotebookApp] Nudge: attempt 120 on kernel 14569df8-e4d1-4847-ae1f-c68e13feeed8 [E 16:25:40.479 NotebookApp] Uncaught exception GET /api/kernels/14569df8-e4d1-4847-ae1f-c68e13feeed8/channels?session_id=05319f9c28b3455cad1b9f4fcf9e0e41 (127.0.0.1) HTTPServerRequest(protocol='http', host='localhost:8888', method='GET', uri='/api/kernels/14569df8-e4d1-4847-ae1f-c68e13feeed8/channels?session_id=05319f9c28b3455cad1b9f4fcf9e0e41', version='HTTP/1.1', remote_ip='127.0.0.1') Traceback (most recent call last): File "/gnu/store/zkjmzfd8li7p7yaihm9rs617vqq9n5qh-python-tornado-6.1/lib/python3.8/site-packages/tornado/websocket.py", line 956, in _accept_connection await open_result tornado.util.TimeoutError: Timeout ``` Attempting to run anything in the notebook such as `;;guix environment matplotlib-env <- python-ipykernel python-numpy python-matplotlib` simply does nothing. I'm not sure if this is an issue with me misconfiguring something or if it's actually a bug, but I haven't been able to chase it down as I don't really understand the internals of Jupyter all that well. Adding `python-ipykernel` and using a Python kernel works fine. -- Domagoj --4lzAAPOIwi+pw8hv Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEE7JyU1wrLyiw5G92zcc2InUujXj0FAmDggpwACgkQcc2InUuj Xj021A/+LHBoHATEJsfucdrEcdjSwa86OXyNoWPyaO82aqY9Qrs96X0rAXaTxHih 6WUW5MPJ1BhFxF4bvSFmt38cXVIUWAjcTKtVH9QS7nBGatBwMZ1+es3X5bJNKO0O wfMJx/yuzKaEMOUhfE5q2dP/inPry1vaNBXZLeYtJ6sEI+ZWldvDXp9tvOpyXznc 0acLrAfRb0ZB86aH6nICn6Bfz6ED6alR3yDIUKgjM0Dfup7z+RBGnRbPHep4m/Ri 7tOMlil30UDHQ4/sp0NpvpJr0PvZO895bFJ6XRhNfYRJoR3rQW87N8xG9RvzV5yb 8AMio7NJfD5kchEoMXWoYZqq5yc4JMCEHNTIi7e6ZOieUsAOahGF5bPApgmhAHpp VawwE8iiVhUlA7XBvaMBPx+/FNtY7+pO0DtcM0rJM/0mwIrLFX8nL0cUi31v417l esXLKihajvG0EqmWd/3sqOuIkVg2UUy0Dqf/RKdz4KR3hcSszqhubmDht7+BYSJx LY72QfPLJCvrLr/iJNsvqnZXNw08/aEG4TR/hxQEG8mUtIyKtjCQX40pHVwtJII9 +1OTfAJnYzVlMpEHZEpTMOmEvYpDadUzU4CR0l5yBcBvWbkFmz9bpWjLRJHTr3wl /N/MuFLkHA3HsYKTJqGL5WPqwJyJvxj0Xoen4JjCuzZMI7tGX4s= =Nn+L -----END PGP SIGNATURE----- --4lzAAPOIwi+pw8hv--
