Widgets wont show in HTML/Azure/NBViewer

So from my running my notebook the widgets work fine, but saving them as html, uploading them to azure/github/nbviewer and then opening them through the link, the widgets don't display.

With a basic example I get "
interactive(children=(IntSlider(value=5, description='n', max=10), Output()), _dom_classes=('widget-interact',…"

displayed where the output widget should be.

Is there any way I can share my notebook so that the other user does not need to install ipython/jupyter to see the widgets?

Where is the option to change the local host port?

Sometimes to spice things up I change the local host port, and I was wondering where this resides in Django?

[D] Why is Z-dimension for GANs usually 100?

I'm playing around with GANs, I've got a question which I can't find answer for. Why is Z-dimension (random vector noise) for GANs usually 100? I saw a lot of GitHub projects and online tutorials, seems like the random vector has always the size of 100. Is it confirmed that it gives the best results? What if I changed that to e.g 1000? How does it affect the generated images?

Data Scientist interview in Python: what essential knowledge should I have?

If you search "Python Interview Questions" on this subreddit, nearly every one has a top comment along the lines of "these are rubbish". So, tell me, for a Data Scientist job requiring 5 years of Python, what should you know? Are there any resources that are *actually* any good?

Migrating database(MySQL to PostreSQL): Attach migrated database to application

Good day,

I would just like to get some idea/s on how to do this task properly. I am a newbie in programming and got a job as Django Dev. My current task is to migrate a MySQL to PostgreSQL. Reading resources online, I found out this tool which helps me do a test migration in my local environment [https://github.com/dimitri/pgloader](https://github.com/dimitri/pgloader) .

MySQL database has 70 rows. I can confirm that when I access postgresql in cli, I can see all the tables as well as the data. Now my problem is, this is my first time to perform this kind of task. I have no idea how will I attach the database to our applications. The rows and fields from mysql database are not matched fully identical to our fields in [models.py](https://models.py) . Perhaps typing manually to admin is an option but its tedious especially if we will encounter this task again. I am planning to automate it.

Can someone share some light here to a newbie? Sorry for the long post, I just don't know how to approach this.

Thanks,

J

Obtaining value in views.py from template

I've got the following code within my html template:

Template

<div class="submitbutton"> <a href="{% url 'accounts:customerhomepage' %}" target="_blank" value="1"> <button> View Demo </button> </a> </div>

I'd like to pass the value of 1 to the function in views.py that will render the page. Within the view, I've got the following code.

Views.py

demo = request.GET.get('value')
print(demo)

The printed result is 'None' rather than '1'. I'm not sure where my code is wrong.

Thanks!

Separate Project, same database

I have a django project which needs some infinatly looping background tasks. Because I want to decouple this from my webserver (for scalability among others) I want to create a separate project that handles these backgrounds threads, where the projects will communicate over an message broker like RQ. here's the catch, both projects need access to the same database. Now I have two options. Either share the database(my prefered option).
Or keep 2 separate databases in sync(potential horror).
for the first option I would love it if I could import the models I defined in my django models, so I don't have to worry about keeping my database models in sync over two projects, and not have to worry about writing one database in sqlalchemy and the other in the normal django orm.
Any suggestions?
