How to solve this issue of Jupyter extension loaded from C and jupyter application directory is something else.I am unable to use numpy and matplotlib in Jupyter notebook.
this is what I get in Anaconda Prompt
These are the two errors I get 302 and 404 when I host the notebook
This is I got when I run a code in notebook
continued...error I get
It usually happens when the application is not able to initiate or determine a default browser. Just copy the entire link http://localhost:8888/?token=4e558da5a28601f99fbc0f1773a4200c57e89b6d487de19a and paste it in a web browser similar to how you access any web url. Remember, the token changes every time you initiate the jupyter notebook.

I'am trying to open Jupyter Notebook from Putty. I have a server where is installed Python and Jupyter. I followed all the steps from this post Remote access Jupyter notebook from Windows but it doesn't work. I got the error: This site can't be reached.
Any idea?
Thx
edit: I added a photo with the ps from putty and the error from browser. It's said:
This site can't be reached
.
The good old logout/reboot mechanisms work in this case too!
You can try closing the jupyter connection in the tunnel's connection, logout from the remote server, re-connect and try. Has worked a few times for me today.
If that doesn't work, there might be stale jupyter notebook processes on the remote server. Query for them and kill them and then logout-log back in and try.
If that still does not work, try implementing your code through ipython to check if Jupyter is working at all, even if its user interface isn't loading on your browser.
I am setting up an API script and I am using Jupyter Lab on a virtual machine. When I run the cell with the login code, I get the following error.
WARNING: We could not open a usable web browser for authentication purposes, or alternatively, please copy the below link:
I then have to manually copy the link into a new browser tab and the API will work. My question is around automating this, is there any way I can have my script copy the link from the Jupyter notebook output cell and then automatically copy it into a new browser tab?
[enter image description here][1]After Launching Jupyter Notebook, the web page from where we can use jupyter notebook is buffering it is unable to redirect to localhost 8888.
Even if I am trying to open that localhost 8888 page it's not opening.
For a long time, it buffers then shows unable to reach.
When I tried to launch Notebook:
When I tried to access directly via localhost address:
I have just started to use virtual environment and tried to create one for Jupyter Notebook, and almost succeeded but when I tried to open a new notebook it gave the error "unable to connect to kernel or server":
Refreshing the browser, clearing the browser cache , restarting anaconda etc also did't fix the problem!
Can you tell me how to fix it?
This happens most times, try restarting anaconda it should fix the server issues, also clear browser cache.
I'm running Jupyter notebooks (Python 3) on a remote cluster that I'm connected/tunneled to over SSH.
Jupyter's default behavior is to try to open the dashboard in a web browser when it launches -- aparently (I only just updated), at some point they switched to the Python 3 webbrowser library for this.
According to webbrowser's documentation:
text-mode browsers will be used if graphical browsers are not available or an X11 display isn’t available.
This is exactly what happens. I run jupyter notebook, webbrowser launches elinks, and my one-time authentication token gets eaten, preventing me from connecting to the notebook.
Jupyter isn't configured to use a browser -- c.NotebookApp.browser is commented out in my config -- and running BROWSER="" jupyter notebook doesn't help either.
How can I force Jupyter not to open any browser?
jupyter-notebook --help includes the following:
--no-browser
Don't open the notebook in a browser after startup.
jupyter notebook --generate-config
Then edit ~/.jupyter/jupyter_notebook_config.py and Add
NotebookApp.open_browser = False
You can achieve this by specifying --no-browser:
$ jupyter notebook --no-browser
I also recommend that you specify the port you want to use:
jupyter notebook --no-browser --port= <port_number>
ie:
$ jupyter notebook --no-browser --port=8888
You have to keep in mind that when you do this, jupyter will provide you with a token on the console, token that the server will ask you when connect remotely through the browser.
If you want to simplify this procedure, you can set a password that is easier for you to remember. To do this, you can run in a console:
$ jupyter notebook --generate-config
and later:
$ jupyter notebook password
This last command will ask you for the password that you wish to use to enter remotely.
Regards!
