Jupyter note notebook is not giving token while starting - python

Jupyter note notebook is not giving token while starting. I try to run it on cloud machine and since no token is given anyone having ip address:port can access it.
I start my notebook in docker image using
jupyter notebook

Try this?
I would recommend running Jupyter as its own docker container. With this you should just be able to do a docker pull and docker run with the correct commands

Run local code in the Jupyter notebook on remote server via kernel

I want to run local code using local data on a remote server and get back execution results back to my Jupyter notebook cells.
Not usual scheme "run Jupyter notebook remotely, connect to remote notebook via ssh tunneling" but more sophisticated via custom remote kernel which I may choose from the kernel list, and run local code on remote server seamlessly.
Some packages (like this -- https://pypi.org/project/remote-kernel) mention that it is possible, but look dated and come with limited usage instructions.
Anyone knows how to implement this? If so, be as more detailed as possible, thanks!

How to run a google Colab Notebook from terminal?

Suppose I have a Google Colab Notebook in an address like below:
https://colab.research.google.com/drive/XYZ
I want to keep it running for 12 hours, however, then again I want to turn my computer off. As a solution, I can connect to our Lab's server via ssh. The server is running all the time. I would like to know if it's possible that I load and run the notebook there?
I found a solution to connect to a Google Colab Session via ssh (colab_ssh package), but it again needs a running Colab Session.
I also tried to browse the link with lynx, but it needs login and this isn't supported by this browser.
Yes, it is possible. You would first need to download your colab notebook as an .ipynb file, then copy it to your server. Then, you can follow one of the guides on how to connect to a remotely running jupyter notebook session, like this one. All you need is the jupyter notebook software on your server, and an ssh client on your local computer.
Edit: I forgot to mention this: To keep your session alive even after closing the ssh connection, you can use tools like screen. The link provides more detailed explanation, but the general idea is that after connecting to your server, first you need to create a session like this:
screen -S <session_name>
which will create a new session and attach you to it (which is the term used when you are inside a session). Then, you can fire up your jupyter notebook here, and it will keep running even after closing the ssh connection. (You just have to make sure you don't kill the screen session using Ctrl+a followed by k)
Now, you have an indefinitely running jupyter notebook session on your server. You can connect to it via
ssh -N -f -L localhost:YYYY:localhost:XXXX remoteuser#remotehost
as mentioned in the first linked guide, use the browser to run a code cell on your jupyter notebook, and then turn off your laptop without worrying about interrupting your notebook session.

Connect to remote python kernel from python code

I have been using PaperMill for executing my python notebook periodically. To execute compute intensive notebook, I need to connect to remote kernel running in my EMR cluster.
In case of Jupyter notebook I can do that by starting jupyter server with jupyter notebook --gateway-url=http://my-gateway-server:8888 and I am able to execute my code on remote kernel. But how do I let my local python code(through PaperMill) to use remote kernel? What changes do what to make in Kernel Manager to connect to remote kernel?
One related SO answer I could find is here. This suggests to do port forwarding to remote server and initialize KernelManager with the connection file from the server. I am not able to do this as blockingkernelmanager is no longer in Ipython.zmp and I would also prefer HTTP connection like how jupyter does.
Hacky approach - Set up a shell script to do the following :
Create a python environment on your EMR masternode using the hadoop user
Install sparkmagic in your environment and configure all kernels as described in the README.md file for sparkmagic
Copy your notebook to master node/use it directly from s3 location
Run with papermill :
papermill s3://path/to/notebook/input.ipynb s3://path/to/notebook/output.ipynb -p param=1
Step 1 and 2 are one time requirements if your cluster master node is the same every time.
A slightly better approach :
Set up a remote kernel in your Jupyter itself : REMOTE KERNEL
Execute with papermill as a normal notebook by selecting this remote kernel
I am using both approaches for different use cases and they seem to work fine for now.

Invalid token when trying to login into Jupyter notebook with Docker jupyter/tensorflow-notebook

I pulled a (seemingly popular, supported by Jupyter) jupyter-tensorflow Docker image using
docker pull jupyter/tensorflow-notebook
and started it successfully with
docker run -p 8888:8888 jupyter/tensorflow-notebook
However, upon navigating to http://127.0.0.1:8888/?token=177a...., I am prompted for a password or token (despite the token already being present in the URL).
I know of no password to use, and the token 177a... does not work.
Any suggestions?
The answer turned out to be quite easy: there was an other Jupyter notebook server I wasn't aware of running. Closing it did the trick.

Running IPython notebook in the background using tmux

I am trying to run a IPython notebook in the background using tmux. For it, I am following this link in stackoverflow. In the tmux terminal, When I run the code jupyter notebook notebook.ipynb, it does give the link to run the notebook in the browser.
But browser displays the following message: "This site can’t be reached
localhost refused to connect."
How can I solve the issue?
Looks like you're running this on a remote server. You just have to edit the link : replace the word localhost with ip address of the remote server.
hostname -i returns ip address on ubuntu machine for instance.
