[PYTHON] How to use jupyter notebook with ABCI

Preparation

Use 3 terminals.

A shell for connecting to ABCI.
For port forwarding
For SSH tunnel

The shell machine assignments used in the following "procedures" are as follows.

--[username @ es1 ~] $: ABCI's interactive shell (where you log in and enter first) --[username @ g0001 ~] $: ABCI compute node (where you can enter with qrsh) --[username @ local ~] $: Local shell

procedure

Run compute node with qrsh

[username@es1 ~]$ GROUP=YOUR_GROUP_NAME
[username@es1 ~]$ qrsh -g $GROUP -l rt_F=1 -l h_rt=01:00:00


2. Get the host name

Make a note of the acquired value as you will need it later.

 ```bash
 [username@g0001 ~]$ hostname
 g0001.abci.local
 ```

3. Run jupyter-notebook

 ```bash
 [username@g0001 ~]$ jupyter notebook --ip=`hostname` --port=8888 --no-browser
 ```

4. Port forwarding on your local PC

 ```bash
 [username@local ~]$ username=your_user_name_in_abci
 [username@local ~]$ identity_file=~/.ssh/your_identity_file
 [username@local ~]$ ssh -i $identity_file -L 10022:es:22 -l $username as.abci.ai
 Welcome to ABCI access server.
 Please press any key if you disconnect this session.
 ```

5. Create an SSH tunnel in another terminal

Note that the host name obtained in 2 is used.

 ```bash
 [username@local ~]$ qrsh_host_name=g0001
 [username@local ~]$ username=your_user_name_in_abci
 [username@local ~]$ identity_file=~/.ssh/your_identity_file
 [username@local ~]$ ssh -N -L 8888:$qrsh_host_name:8888 -l $username -i $identity_file -p 10022 localhost

 ```

Access `http://127.0.0.1:8888/?token=~` displayed in 6.3

Since the local URL is displayed in the shell of the calculation node running jupyter-notebook, when you access it, Jupyter-notebook opens in the browser.
