I set up my EC2 and I configured my jupyter notebook config file like here: https://chrisalbon.com/jupyter/run_project_jupyter_on_amazon_ec2.html.
I now run: jupyter notebook, and here's what I get:
[I 03:42:26.400 NotebookApp] Serving notebooks from local directory: /home/ec2-
user/courses/deeplearning1/nbs

[I 03:42:26.400 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to
skip confirmation).
However, now that I'm trying to go to my site (http://ec2-54-202-213-129.us-west-2.compute.amazonaws.com:8888/), here's what I see on my terminal.

Any idea what I'm doing wrong?
At first did you try to use https:// instead http://? I.e. https://ec2-54-202-213-129.us-west-2.compute.amazonaws.com:8888/
Regardless of this I think you should follow the recommendations from official documentation: http://jupyter-notebook.readthedocs.io/en/latest/public_server.html#using-ssl-for-encrypted-communication
Create cert and key: openssl req -x509 -nodes -days 365 -newkey rsa:1024 -keyout mykey.key -out mycert.pem
Then start your notebook this way: jupyter notebook --certfile=mycert.pem --keyfile mykey.key

I am trying to install/use Anaconda on my pc with Windows 10.
After installation, Anaconda will not launch.
If I enter anaconda-navigator in the Anaconda Command Prompt i receive the error included at bottom of post.
I tried to update conda to resolve using conda update conda, conda update anaconda-navigator, anaconda-navigator --reset
all of which render “environment variables: conda info could not be constructed. KeyError(‘pkgs_dirs’)”.
I tried conda info to find the .condarc file but received a DLL error.
I tried adding anaconda3\Scripts to path but that hasn’t helped.
Here's a pic of my path vars if it helps:

What could be the issue here? I see less dll files (around 400 only) in C:\Windows\System32 compared to servercore/server image (This is working fine with windows servercore image.)
I am using Jupyter notebooks via anaconda. When saving a new notebook to a specific directory, the whole directory becomes inaccessible, showing this error (image and text below). Other directories and the notebooks inside them are still accessible and able to be run. I am able to save new notebooks and run them in other directories no problem.
Error:

This is strange as i have been working in this directory and saving numerous notebooks to it without error until today. I can delete the notebook that caused it to crash and then it returns to normal and i can run notebooks that were already saved before today.
I am unsure if this is related or not but i also have an issue whereby i have to run python -m ipykernel install --user every time i change to a new environment in anaconda, otherwise the executable remains as that of the last environment i ran that command with. Perhaps this is useful i'm not sure, if anyone had advice with this too i'd be grateful.
I have also tried making a new directory, copying over the contents of the dysfunctional directory, and then making a new notebook from there, however this causes the same error.
I did try uninstalling and installing Anaconda, but the problem remains the same.
Windows 10 x64, latest Anaconda
Installation goes fine, but when I start Spyder it reports this:
"You have missing dependencies, nbconvert >=4.0": None. However, nbconvert is already installed.
It prompted me to install Kite, when I did it says Kite installation error.

I am running a flask application using plotly for some of my charting figures, and it runs fine on my work pc.
I have just tried to run it on my personal pc and on starting the local host server I am getting the following message:

So it's obvious from the error message that it is an issue with permissions regarding the .plotly.credentials file - but I have assigned myself full permissions to the whole .plotly folder through the security settings and I have also pip installed plotly as an administrator.
I've tried extensive Googling , but there doesn't seem to be much windows related advice regarding this particular issue.
Can anyone suggest how I can get this to work.
