NNI如何搬到Colab02

若看到以下画面，恭喜你，又成功了！

/bin/bash: -c: line 0: syntax error near unexpected token `newline'
/bin/bash: -c: line 0: ` ./ngrok authtoken <your-authtoken>'
INFO:  Starting restful server...
INFO:  Successfully started Restful server!
INFO:  Starting experiment...
INFO:  Successfully started experiment!

The experiment id is 5Ohd94VC
The Web UI urls are: http://127.0.0.1:5000   http://172.28.0.2:5000
------------------------------------------------------------------------------------

You can use these commands to get more information about the experiment
------------------------------------------------------------------------------------
         commands                       description
1. nnictl experiment show        show the information of experiments
2. nnictl trial ls               list all of trial jobs
3. nnictl top                    monitor the status of running experiments
4. nnictl log stderr             show stderr log content
5. nnictl log stdout             show stdout log content
6. nnictl stop                   stop an experiment
7. nnictl trial kill             kill a trial job by id
8. nnictl --help                 get help information about nnictl

第四步，检查the public url. 请注意，不可更改 Port no. 4040 ！

! curl -s http://localhost:4040/api/tunnels # don't change the port number 4040

执行上个步骤後，你将会发现如下的字样[ http://xxxx.ngrok.io ] 。直接连入此public url.，即可进入NNI WebUI。
