Cannot open Jupyter notebook, multiple errors. #646

DrBanana419 · 2021-07-15T08:52:09Z

When I try to run sage -n jupyter I get this (excluding the banner):

`Please wait while the Sage Jupyter Notebook server starts...

Although I'm not sure if this is a sage issue or a jupyter issue. Here are my installed Jupyter packages (got from emerge -s jupyter):

It looks like a network configuration problem on your machine. Do you have some kind of firewall running?

I didn't explicitly install a firewall, so no.

Have you ever run a standard jupyter notebook on that machine (i.e. not a sagemath kernel but a python or possibly other kernel)?

DrBanana419 · 2021-07-15T10:13:51Z

Have you ever run a standard jupyter notebook on that machine (i.e. not a sagemath kernel but a python or possibly other kernel)?

I have done it on another Linux distribution, but not on Gentoo.

kiwifb · 2021-07-15T10:15:00Z

You should be able to do so with jupyter notebook on the command line, I am curious to see if it will behave differently.

DrBanana419 · 2021-07-15T10:19:24Z

Unfortunately jupyter notebook returns the same errors.

kiwifb · 2021-07-15T10:23:44Z

Which means it is not a sage specific problem, as I expected. Can you post the content of /etc/hosts and possibly the result of ip address?

DrBanana419 · 2021-07-15T10:28:19Z

These are the contents of /etc/hosts (minus the comments):

127.0.0.1	localhost
::1		        localhost
127.0.1.1	my-linux-pc.localdomain	my-linux-pc

And this is ip address:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: enp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether a8:a1:59:3c:87:65 brd ff:ff:ff:ff:ff:ff
    inet 192.168.0.4/24 brd 192.168.0.255 scope global dynamic noprefixroute enp4s0
       valid_lft 4798sec preferred_lft 4798sec
    inet6 fe80::b545:860e:c7f5:5fb4/64 scope link noprefixroute
       valid_lft forever preferred_lft forever

By the way I tried jupyter notebook --ip="0.0.0.0" and that worked.

kiwifb · 2021-07-15T10:39:00Z

Then sage -n jupyter --ip="0.0.0.0" may work, although I must say I am confused by the fact that address works. Shows my ignorance on network stuff I guess.

DrBanana419 · 2021-07-15T13:19:29Z

I think that this should be kept open since workarounds like this should not be needed.

kiwifb · 2021-07-15T20:16:32Z

If you wish, but you should seek assistance from a jupyter help channel. They are more likely to figure out the issue.
