Made use of my Python knowledge professionally for the first time!

I’m a mechanical engineer, but love learning new things. In the last few years, I’ve taken several edX courses on python, and loved learning about it. I generally just tinker around keeping the basics fresh, but recently I had an opportunity to speed up some data analysis at work, and was able to use python to do it!

As part of our testing, we generate some large csv files (generally 1-4 gb), which were a real pain in the ass to work with in excel. Using python and pandas, I wrote a short piece of code (200 lines) to parse our data, strip out the junk, and plot it into a presentable form. Now there are like 5 people using it on a regular basis!

This is a big deal for me so I wanted to share it. Even dumb mech e’s can use computers!

How to host dynamically generated images in Google Cloud Storage?

Hi there, I've been trying to figure this out for hours, bouncing from tutorial to tutorial, so I thought I'd post it here in hopes someone might be able to give me some simple pointers:

​

I have a Django project that uses PyGal to generate some nice looking sag charts to use in a report we're creating, using `return self.chart.render_to_file(settings.STATIC_ROOT + 'myapp/graphs/graph.svg')`. The charts are saved to disk and then loaded into the Django templates for the report, which is then converted to PDF using PyGal.

​

This works fine developing locally, it updates the file overwriting if need be, and the HTML references it fine. However, as I begin to look at deployment and experiment with that, I still haven't been able to get it working running Google Cloud.

​

My Google Cloud setup is: Django is running in a container on Kubernetes, database is Google's CloudSQL MySQ, and I have a storage bucket called `myapp-production-static` where I serve static files from. This works fine for static files (images, css, etc), however, I can't for the life of me figure out how to get Django to write the chart.svg files into the storage container that STATIC is successfully pointing at.

​

Has anyone else successfully done

how to use a django form to update 2 related tables.

​

Hi guys,

​

I'm very new to python and django, I started django about a week ago. So far things seem quite straight forward, however I'm stuck on a concept and could do with some advice on best way to proceed.

​

I've decided for a first django project to make a cooking recipe for my wife. probably a bit ambitious for a first project but its all good learning :D

class Ingredients(models.Model):
name = models.TextField()

def __str__(self):
return self.name

class Category(models.Model):
food_category_name = models.TextField()

class Recipe(models.Model):
food_category = models.ForeignKey(Category, on_delete=models.CASCADE)
recipe_name = models.TextField()
recipe_description = models.TextField()
picture_item

[P] Browse State-of-the-Art Papers with Code

[https://paperswithcode.com/sota](https://paperswithcode.com/sota)

Hi all,

We’ve just released the latest version of Papers With Code. As part of this we’ve extracted 950+ unique ML tasks, 500+ evaluation tables (with state of the art results) and 8500+ papers with code. We’ve also open-sourced the entire dataset.

Everything on the site is editable and versioned. We’ve found the tasks and state-of-the-art data really informative to discover and compare research - and even found some research gems that we didn’t know about before. Feel free to join us in annotating and discussing papers!

Let us know your thoughts.

Thanks!

Questions about flask html rendering.

I started web development with flask, with all server side routing and rendering. Now I am in the process of learning single page with react where flask (I think) renders only the first page then after that returns only JSON. So my question is, have I progressed as a programmer? i.e. will I mostly use flask like this now, as an api? Or are there situations where I might create a modified single page where I still render some pages with flask, and along with that still use jinja2, flask_wtf, flask_login, etc... the bulk of the flask extensions that I have learned thus far?

Django CMS - add Placeholderfield with TextPlugin from script

Hi reddit,

My friend have a blog on old django cms 2.X

I'm trying to help him automate some stuff, like create post in dropbox paper and export it to html with all text formatting stuff, and add it as a draft to his blog.

And my problem is :

How can i get instance of PlaceholderField, and add 'TextPlugin" in it from outside script

Models looks something like this :

class Post(models.Model):
author = models.ForeignKey(Author, verbose_name=_("Author"), blank=True, null=True)
........
draft = models.BooleanField(default=True)

class PostData(models.Model):
post = models.ForeignKey(Post, verbose_name=_("Post"))
post_content = PlaceholderField('Posts Content',related_name="%(app_label)s_%(class)s_posts_content")
......

My script is simple as f:

html_data = """<b>formatted html from dropbox paper</b>"""

author = Author.objects.get(id=1)
new_post = Post(author=author,draft=True, ...)
new_post.save()

post_data = PostData(post=new_post,language='en', post_content=???????)

I've read somewhere to override save method in PostData ie:

Trouble with HTMLCalendar

I'm having trouble with setting the first day within an HTMLCalendar to Sunday. Here is my code:

&#x200B;

I'd like to make Sunday the first day in my calendar, but I'm not sure how to. I know that calendar.setfirstweekday() is a method that can be used for calendars, but I don't know that it's available for HTMLCalendar.

**utils.py**

class Calendar(HTMLCalendar):
def __init__(self, year=None, month=None, user=None):
self.year = year
self.month = month
self.user = user
super(Calendar, self).__init__()

Views.py

class CalendarView(generic.ListView):
model = Event
template_name = 'accounts/calendar.html'

def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)

[Project] nlp-tutoral repository who is studying NLP(Natural Language Processing) using TensorFlow and Pytorch



Hello. This is my first post in reddit

I created nlp-tutoral repository who is studying NLP(Natural Language Processing) using TensorFlow and Pytorch inspired by other example code.

You can see NNLM which is first language model, baseline model such as RNN, LSTM, TextCNN, Word2Vec in NLP. Also You can more easily learn NLP model, training steps as implemented Only ONE file (\*.py) from seq2seq, attention, bi-LSTM attenton, Transformer(self-attention), to BERT model.
I implemented with Pytorch, Tensorflow both.
