[D] How common is porn in datasets?

Earlier on today I had an issue with annotation data on an image in the coco-text 2014 dataset, I display the image, and it's a dude in a bunny suit screwing a woman with the caption "The fuck bunny says congratulation in his own very special way" ([sfw crop I think](https://i.imgur.com/MVUcPlL.png)). Is that a common occurrence? I'm not very happy to have that pop on my screen with coworkers around!

Aiming to fill skill gaps in AI, Microsoft makes training courses available to the public

Hi guys.
I came across this in r/technews and thought it would be useful here; particularly if you are looking at using python for data analysis/machine learning etc.

>This computer science course provides an overview of AI, and explains how it can be used to build smart apps that help organizations be more efficient and enrich people’s lives. It uses a mix of engaging lectures and hands-on activities to help you take your first steps in the exciting field of AI.

Ways to implement license control in an app developed in python

Hi, my company is currently converting some apps in C (most of them over 20 years old) to python. These apps though use a C library that controls that they are only used in certain machines (the library has pre loaded hostids and checks if the host id of the machine the software is running is on that list) and for some real time computation some of the apps store transaction data in memory and the license file also has store the max number of records that is allowed in memory for that particular app for the particular customer (based on hostid also).

Since this license library is in C and is always delivered to customers compiled, customers cannot tamper with it. I am looking for ways to implement something similar in python (which the app is a set of py files and can be easily read) that is also hard to temper with. Does anyone have any ideas around this? I suppose this would be of common interest for apps that depend on licenses for execution in general.

Thank you

Plot spacing

Is there a way to add more space between histogram plots in the same output cell? I have 50 histograms generated from the same cell and they appear too close together to clearly read, Im curious if there is a way to add more space between them without having unique cells for each plot. [Here is an screenshot of what I'm talking about.](http://i65.tinypic.com/168a5ax.png)

I've have tried to google around for an answer but cant seem to find one.

Starting a plotly dash app from another py file

Hey guys,

I'm experiencing a weird issue with plotly dash that I can't seem to figure out.

When the dash app is run by itself, it works perfectly fine. The server starts up, gives the debug pin, and you can access it from the web browser.

Now here is the issue I am having.

I have created a text-based menu when you pick an option, it executes a def, and executes a specific part of the program.

When I import the dash app into the menu, and try and call it, it will run as I get the following:

* Running on http://127.0.0.1:8050/ (Press CTRL+C to quit)
* Restarting with stat

But after this, I don't get the debugger pin or anything else, and when I go to the page in firefox, it just spins as if it's loading but won't show anything.

How would I properly call this?

Thanks!

Best way to handle categories in a generic ListView?

So on the Home page of my app (which is redirected to /issues/) I have a list of "Issues" that I'm generating with a generic ListView:

class IssueListView(generic.ListView):
model = Issue

This currently loads all the Issues. I am adding a sidebar to that page that can be clicked to load different categories of Issue, so I'd like the url to be updated like /issues/<category>/.

Do I need to write a new IssueCategoryView class to do this? Or maybe I should amend the app so that the Home page is /issues/all/ and have a default "all" category that all Issues belong to?

I'm sure this is straightforward but I just want to make sure I'm doing this correctly before proceeding.

Thanks

What are your freelance experiences with Django?

What kind of web app is probably the most requested? How much does such a project pay? Do the clients look specifically for Python in Django solution for their job or it just happens they stumble upon Python programmer who does it?

I'm wondering because I'm a hobbyist and I wondered how things look from progressional's perspective.

Is it possible to have multiple post requests in one route() decorator?

Is it possible to have multiple post requests in one route() decorator?

What I'd like to achieve is to have one html page with multiple forms.

I tried something like this but doesn't seem to work.

@app.route('/', methods=['GET', 'POST'])
def index():
if request.method == 'POST':
do_a= request.form['do_a'];
do_b= request.form['do_b'];
else:
....
return render_template('base.html')

Thanks

ELI5 Why do I want to use a tuple instead of a list They seem basically the same other than mutable/immutable

I just don't see the value add. But I end up dealing with them a lot.

[Ask Flask] Is there reason to use db.Column, db.String etc in flask-sqlalchemy instead of sqlalchemy Column, String etc?

I came into Python from languages with very strong language servers and autocompletion due to static typing and I really like Python 3 types system, because it helps very much to develop and avoid most common errors especially for newcomers like me (correct methods, properties and types are suggested by language server/autocomplete)

But I discovered that db from flask_sqlalchemy does not have many members which are being used in clean sqlalchemy environment in a snap with suggestions from editor.

Is there any reason documentation has db.String instead of

from sqlalchemy import String, Column, ...

?

Thanks!

P.S. (link to flask-sqlalchemy doc: http://flask-sqlalchemy.pocoo.org/2.3/models/#simple-example )
