[D] Oxford deep nlp 2017 solutions

My solutions here: https://github.com/mleue/oxford-deep-nlp-2017-solutions

I've recently been going through the lectures of oxford's 2017 deep nlp course (https://github.com/oxford-cs-deepnlp-2017). The course was well presented and I've really deepened my understanding of modern NLP methods.

Naturally I am going through the practicals as well. I've linked to the repo with my current progress but I feel a bit stuck atm.

The main task revolves around a multi-class classification of ~2k transcripts of TED talks. However, the dataset is heavily skewed with one class covering ~50% and some classes only around 3-5% of the data.

Practical 2 wants you to try a basic averaging over word-vectors approach and then pumping that through a single-hidden-layer NN. I've been trying to tweak a lot with preprocessing and tokenization but I can't come beyond ~66% accuracy on the test set.

In Practical 3 you are then supposed to try the same task with a RNN approach. I thought this might get better but I am basically stuck at around the same test set accuracy of ~66%.

Maybe not much more is possible, especially given the fact that there is very little data for some of the classes. Basically I am wondering if anyone else has gone through the course (or even attended the real deal at oxford) so we can get a discussion going.

Thanks in advance! //Michael

[AF] FLASK_DEBUG=1 won't start my flask application?

Hello, so I just found out on Windows that I can't run my flask app when I set the debug to true.

I may have done something wrong with config files? Or is it the fault of cmder where I try to tun this app? Or ... I don't have a clue. Pretty new to this.

Log:

D:\Programovani\github\beta-issues (master)

Without debug the app starts normally.

What CMS would you recommend for a basic brochure website?

Hi all,

I have been designing a "brochure" travel agency website with lots of content pages. I am at the stage where I need to start thinking about the backend. This will pretty much be my first web project / deployment.

The people who will be maintaining the site aren't very technical so I was looking for a nice and simple CMS (I think the standard Django admin won't cut it) so I was looking at a few different options like Django-CMS, Mezzanine, etc... Although some of these seem a bit overkill?

The features we are looking for are pretty much just keeping content updated on pages, adding/removing pages and maintaining a blog.

Reddit, what would you recommend? Thanks!

How do you push updates to your Django website? Please help, prepare for the impending cringe.

I have a Django website on DigitalOcean. I used the one-click app for Django, and through many frustrations I ended up just overwriting the default app with my own app's code (I sshed in, pulled my git repo into a separate folder, and merged the folders with the existing one-click app default code).

When it comes to updates to my website code, I am currently forced to either A: ssh in and manually edit files with Vim or B: ssh in, pull my repo into a separate folder, and manually mv the new files into the correct Django project folders.

I understand if you're cringing really bad right now. Do you have tips on how I can improve my workflow?

* Should I put the entire project inside a Docker image?
* I have experience running databases inside Docker, but not entire projects. Would my PostgreSQL database go into a *separate* Docker image??

* Is there any way for me to set my repo up so that I can simply push to the `master` branch and that code gets written to my production server?

* It doesn't bother me to dish out more $$ for convenience in regards to hosting. This being said, do you have any suggestions as to which host I should be using?

I need some help embedding a graph

I need some help getting a graph displaying on my site. For reference, I'm using matplotlib and mpld3 to do this. The graph itself seems to be working, but when i convert it to a JSON string to embed it in the HTML, I get a blank page. Then, the second time I try to load the page, there will be a runtime error: "main thread is not in main loop." I've been stuck on this for days lol, any help is appreciated.

I'm struggling with implementing dataTables into my django app. StackOverflow tells me that jquery must be loaded first before the datatable.min.js. Did that already and it still doesn't work. HELP!!!

[Solved!](https://www.reddit.com/r/javascript/comments/69wcum/im_struggling_with_implementing_datatables_into/)

I'm just trying on replicating the datatable I found from a bootstrap theme into a django format. I'm desperate!

Here's the error that I get.

Uncaught TypeError: $(...).DataTable is not a function

Extending the User Model

Hey guys,

I'm new to Python and Django so I apologize if this is a dumb question, but I'm looking for some guidance/help from your more experienced folks regarding extending the User model.

I want to be able to create users, but add one simple custom field for the user for "region". When a user registers (via a 'sign up' view/html form) I just want to them choose from regions I've specified and it be a value attached to that user.

I thought User.objects.create_user() would have a way to pass a custom field for a user but it seems not? Any help would be great, thanks!

How can I use a form to populate empty fields in a model class' pre-existing instances?

[This is a snapshot of the django site I'm creating.](http://imgur.com/a/LmJen) Each of the content boxes (Corvette, Nathalie Emmanuel, etc.) is produced by iterating through instances of a model called "Noun."

There's one exception... the "Rating score" form field. That's pointed to a separate model called "NounScore." I can't figure out how to get each "Rating score" field to correlate with each "Noun" that surrounds it.

Every time a new Noun object is created, a corresponding NounScore object is created along with it (using a one to one field and django signals). I linked them together with a one to one field instead of a foreign key because each item is supposed to be rated only once... by a single user. Nouns only appear on the homepage of the user they were created for.

My goal is to increment the primary key of each NounScore object every time the template's for loop prints a new "Rating score" field to the screen.

I'm sorry if this is explained poorly, but I don't really have a clue what I'm doing. [Hopefully the example code helps](https://pastebin.com/mKHWGtBx). Thank you for any help! I'll be sure to pass it on in time.

What's the preferred approach to defining these relations (models and Django Rest Framework serializers)

I've read that circular imports is a 'code smell' and is fundamentally a bad design choice. I have an app that has models, User, Deck, Hand. I want the User to be able to create a Hand without needing to create a Deck, but also give the User the choice to put the Hand in the Deck if wanted. So I end up with something like this:

models.py:

class User(AbstractUser):
pass

class Deck(models.Model):
created = models.DateTimeField(auto_now_add=True)
name = models.CharField(max_length=100, unique=True,
blank=False, null=False)
user = models.ForeignKey('users.User', related_name='decks',
on_delete=models.CASCADE, null=False)


class Hand(models.Model):
created = models.DateTimeField(auto_now_add=True)
deck = models.ForeignKey('goals.Deck', related_name='hands', on_delete=models.CASCADE, null=True)
name = models.CharField(max_length=100, blank=False, null=False)
user = models.ForeignKey('users.User', related_name='hands', on_delete=models.CASCADE, null=False)


serializers.py:

class HandSerializer(serializers.HyperlinkedModelSerializer):
user = serializers.ReadOnlyField(source='user.username')
deck = serializers.CharField(required=False, source='deck.name')

class Meta:
model = Hand
fields = ('url', 'id', 'created',
'deck', 'name', 'user')
extra_kwargs = {
'url': {
'view_name': 'goals:hand-detail',
}
}


class DeckSerializer(serializers.HyperlinkedModelSerializer):
user = serializers.ReadOnlyField(source='user.username')
hands = HandSerializer(many=True, read_only=True)

class Meta:
model = Deck
fields = ('url', 'id', 'created', 'name', 'user')
extra_kwargs = {
'url': {
'view_name': 'goals:deck-detail',
}
}

class UserSerializer(serializers.HyperlinkedModelSerializer):
decks = DeckSerializer(many=True)
hands = HandSerializer(many=True)

...

Is this the correct approach API-design-wise in order to achieve what I want app-design-wise? If not, how should I go about doing this? And if so, how do I get around the circular import errors when I change user from a ReadOnlyField to a UserSerializer() field?
