1 Server installation jupyter

1.1 pip install

pip install jupyter

1.2 The configuration file

View the configuration file .jupyter/jupyter_notebook_config.py, If not found, generate the configuration file

jupyter notebook --generate-config

1.3 Create login password

Method 1 ： First create a password , This password is used to log in locally to a remote server jupyter notebook.

Open... On the server Python Environmental Science , Enter the following code

from notebook.auth import passwd
passwd()
Enter password:   #  Input password , This password is used for remote login jupyter notebook
Verify password:  #  Verify the password again , enter , The following ciphertext will be generated 
'sha1:7***********************87d21'  

Open the upyter_notebook_config.py file , Set access notebook Information about

c.NotebookApp.ip='*'  # * Express all IP, Set up here ip Accessible for all 
c.NotebookApp.password = u'sha1:7***********************87d21'
c.NotebookApp.open_browser = False  #  prohibit notebook Automatically open browser at startup ( stay linux Servers are generally ssh Command line access , There's no graphical interface . therefore , It's no use starting )
c.NotebookApp.port =9000  #  Specify the port to access , The default is 8888

start-up jupyter notebook, Access... From your local browser :serve_ip:9000, appear notebook The login page , Enter the password to use .

Method 2 ： Directly enter the following command on the server command line , This will be done in and jupyter_notebook_config.py Create... Under the same directory jupyter_notebook_config.conf file , There is a ciphertext for entering the password , It can also be used to log in jupyter notebook.

jupyter notebook password 
Enter password: **** 
Verify passsword: **** 

2 SSH Mapping server ip To local

The main idea ： have access to ssh Command to do a port mapping

Let's first learn how to map remote ports to local commands , as follows ：

ssh -L 8080:localhost:9000 [email protected]

If we remote server jupyter notebook Open ports are 9000, Through the above command, we can send the remote 9000 Port mapping to local 8080 port , among user Is the user name of the remote server ,xxx.xxx.xxx It's a remote server ip, The following figure shows the successful interface .

ps: I failed. , I haven't got this interface yet , It's always a mistake , The above is from Other bloggers

ssh: connect to host localhost port 22: Connection refused

3 About jupyter Other questions

3.1 Boot kernel cannot find virtual environment （tf,torch wait ）

There are generally two solutions , Recommended approach 2, Solve the problem at one time .

1. Find... In the virtual environment directory jupyter lab And start the , Generally in /envs/pytorch/bin, type ：

   jupyter lab
   

2. stay base Environment , Type the following command ：

   python -m ipykernel install --name pytorch --display-name torch
   

   among ,pytorch Is the name of your virtual environment , The back is kernel Interface display name .
