[P] Mushroom: Reinforcement Learning library

Hi everyone,

during my PhD I worked on a RL python library which has the purpose to simplify the developing of RL experiments and which is highly customizable to let user add and test their own algorithms. It uses Gym and Pytorch (one can also use Tensorflow or other libraries transparently) to exploit already developed powerful libraries and just to focus on RL aspects. Recently, we added several policy gradient and actor-critic algorithms, such as the recent DPG. I'd really appreciate if you give a look to Mushroom and consider it for doing your research, or simply to give me a feedback on it. Here are the GitHub link: [https://github.com/AIRLab-POLIMI/mushroom](https://github.com/AIRLab-POLIMI/mushroom) and the doc link: [https://mushroomrl.readthedocs.io/en/latest/](https://mushroomrl.readthedocs.io/en/latest/).

Cheers!

During logout on the web the DRF token is also logging out the native app, how do I stop this?

I have an API that is consumed by web client and native clients, when the user on the web logs out the token is invalidated and they are then logged out on mobile which is a bad user experience. How do I solve this?

It is conceivable to just forget the token on the web during logout but then it never changes and there is credit card data stored in the DB so that is not ideal.

How to organize my django website

Hello all! I am super super super new to Django and python in general. I have begun the process of reading the documentation and going through tutorials and have come here for guidance.

The site I want to build would be for speakers at conferences to be able to upload their files prior to the event. I can easily wrap my head around having an app with a model of the general fields associated with this and a simple file upload form.

The part that I can't really figure out is how I would be able to have multiple conferences able to upload at the same time. As well as how non programming people would be able to set up a new conference to begin uploading to using only the admin interface.

Is there a way to create a new db table via admin interface? Should all of the entries just live in the same table with an entry determining which conference the entry belongs to? Am I being too ambitious for my first non-guided Django project?

Replacing a spreadsheet...

I've successfully used Jupyter before, as a beginner for a few machine learning lessons, but I'm wondering if it's possible to use/abuse Jupyter to behave more like a spreadsheet, just in terms of having cells depend on other cells and continually update.

I've always felt limited by Excel because I really want to document my thinking in the way that Jupyter allows, with markdown blocks etc. (Before getting into Jupyter I've also been using Calca for the mac.) I also feel limited by Excel's functions, while I'm very comfortable with software programming - there have been so many times I've thought, ugh, this would be so much easier if I could just call 'map' on this array of data...

So I've been hoping to find something like Jupyter, where I can actually write my own functions and document my thinking, but where I can also input new data and have it be persistently stored, and have other cells update to changed data.

I know this isn't exactly what Jupyter is usually used for, since it's more to explore data in a linear fashion rather than in a reactive-programming fashion. So I guess this is a dual question:

Is it possible to make Jupyter behave

Which frontend do you prefer with Django?

Flask Email Validation - Stop Nonsense Emails

For example, I get some emails that are clearly nonsense like sfdjhkj@kjh.com...

is there no way to mitigate this or some kind of library/algorithm to verify the validity of an email?

Doesn't have to be 100% of the time just in general.

[R] Facebook has released code and pretrained models for Cross-lingual Language Model Pretraining

It's an impressive piece of work that get state-of-the-art results on Cross-lingual Natural Language Inference and unsupervised Machine Translation (even out-performing supervised Machine Translation in some settings).

The model is a cross-lingual implementation of BERT.

Discussion: What to call the "main" app in your Django Project?

I'm starting a new project and it will be a collection of Django Apps with their own functionality (as intended by the Django Framework). However, I usually create a home/base/main app for the landing page, all of the base templates, static files, ... What is the preferred way to call this or handle this?

Following Flask production deployment tutorials, how safe is it to host a small scale webshop using Flask?

I want to host a really small scale webshop - only meant for a Facebook group - on my Raspberry Pi. I've read that I need to properly deploy it for production, which I intend to do.

My plan is to store addresses locally and have PayPal take care of the payments.

How safe/unsafe is this? Is there something I oughta know before I make this?

Error in documentation

Hi,

I am a beginner. I was going through the getting started documentation and found some typos and error.

[https://docs.djangoproject.com/en/2.1/intro/tutorial03/#writing-more-views](https://docs.djangoproject.com/en/2.1/intro/tutorial03/#writing-more-views)

def detail(request, question_id):
return HttpResponse("You're looking at question %s." % question_id)

def results(request, question_id):
response = "You're looking at the results of question %s."
return HttpResponse(response % question_id)

def vote(request, question_id):
return HttpResponse("You're voting on question %s." % question_id)

Gives the following error:

return HttpResponse("You're voting on question %s", % question_id)
SyntaxError: invalid syntax

To solve the problem I performed

*return* HttpResponse("You're voting on question %s", question\_id) #excluded the '%' prefixed to question\_id

​

I am using Linux python3.7 django 2.1.5.

Will the changes be made or should I make an official report on their site?

If so, How should I sent the error to the django team.
