Unable to Access Jupyter Notebook

[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.

Unable to load jupyter notebook

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.

Force Jupyter Notebook *not* to open a web browser

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.

How to link to Jupyter notebook from a local HTML page

I am learning Jupyter Notebooks at the moment. Is it possible to link a Jupyter Notebook to an HTML page.
For example, say I have an HTML page which is on my computer. Can I use this to link to a Jupyter Notebook, so when the link is clicked it loads the notebook in a viewer to be run?
Thanks,
BJR

I am not using Jupyter notebook this way (actually I use Jupyter Lab). However, if I understood correctly you want to click on link on HTML page in your local machine and run notebook.
If trying access Jupyter notebook via HTML link in your machine while notebook (server) is not running or you are using non-default browser while notebook is running you will reach page with following information which should be sufficient to plan you next steps:
Token authentication is enabled
If no password has been configured,
you need to open the notebook server with its login token in the URL,
or paste it above. This requirement will be lifted if you enable a
password.
The command:
jupyter notebook list
will show you the URLs of running servers with
their tokens, which you can copy and paste into your browser. For
example:
Currently running servers:
http://localhost:8888/?token=*****... :: /Users/you/notebooks
or you can paste just the token value into the password field on this
page.
See the documentation on how to enable a password in place of token
authentication, if you would like to avoid dealing with random tokens.
Cookies are required for authenticated access to notebooks.
Setup a Password You can also setup a password by entering your token
and a new password on the fields below:
Token
New password
Basically it means that: link to Jupyter notebook will work if you have started server with token autorhization and use default browser. You can set password which means that you can use whatever browser in your machine but must log in (you can save login credentials in your browser of course). In any case notebook (server) must have been started and running before using link.
Link will not run your notebook, it just opens notebook page.

"No web browser error" for jupyter notebook outside home directory only

I'm a Windows user and my default browser is chrome but i like to use firefox for jupyter notebooks.
When I'm in my home directory, I can easily launch a notebook in firefox with
jupyter notebook --browser="firefox"
Likewise i can get the same effect by setting c.NotebookApp.browser = u'firefox' in the config file.
However, if I switch to any other directory I get this error:
[W 16:10:32.063 NotebookApp] No web browser found: could not locate runnable browser. and no browser will launch. Also if I comment out the browser option in the config file and try to run just jupyter notebook with no options in any other directory it will open, but in chrome.
How can i open through firefox outside of my home directory?
