D Train on full dataset after cross-validation? Semantic segmentation

I am currently working on a semantic segmentation project of oat leaf disease symptoms. The dataset is quite small, 16 images. Due to time constraints, I won't be able to extend this.

I am currently training 3 models, 3 backbones, and 3 losses--using 5-fold cross validation and grid search.

Once this is done, I plan to then run cross validation on a few different levels of augmentations per image.

My question is this:

Once I have established the best model, backbone, loss, and augmentation combination, can I train on the full dataset since it is so small? If I can do this, how do I know when to stop training to prevent overfitting but still adequately learn the data?

I have attached an image of some results so far.

Thanks for any help you can provide!

Configuration format

I currently use JSONs for storing my configurations and was instead recommended YAML by a colleague. I tried it out, and it looks decent. Big fan of the ability to write comments. I want to switch, but wanted to get opinions regarding pros and cons from the perspective of file size, time taken to read/write and how stable are the corresponding python libraries used to handle them.

My typical production JSONs are ~50 MB. During the research phase, they can be upto ~500 MB before pruning.

Moving to Canada Soon! Looking to Connect with Fellow Django Devs

Hey everyone! I'm moving to Canada in about four months, and I'm excited to connect with people working with Django. I have around three years of experience building large-scale Django apps that handle millions of data entries, and I'm always looking to improve and learn from others.

If you're in Canada or familiar with the Django scene there, I'd love to hear any insights, or tips, or just chat about the latest in Django development! 😊

How do I compare a form in CKEditorField and StringField?

I am using flask and flask-sqlalchemy and flask-wtf-forms.


Imagine I have 2 forms where one form is placed in each flask route.

Lets start with the first route and the first form.

The 1st form has the flask wtf field CKEditorField. Within the route I type zzz in the form. Next I save this in the Posts table as the content column. Now lets switch to the second route and second form.


In the 2nd route I am using StringField. Then in a form, I input/type zzz.
Now I am using a custom validator in the form and I query one_or_None for the Posts table. If Posts returns something I then test if posts_db.content == content_form' I raise the validationerror('the post is not unique"). This should work but what if I use something like bold in the ckeditor form. How would I get the output in the second Stringfield form? The only solution I can think of is passing on the variable posts_db in the route. Does anyone have any other suggestions?




TLDR:

I have 2 forms. The 1st form being CKEditorField ,in the 1st route, which I fill with the text 'zzz' then save it the Posts db

How did you first learn about Python?

How did all of you stumble upon python? I saw someone writing python in RuneScape one day and became curious. Then I dipped into front end frameworks like html and css, then JavaScript and python

Django and iOS/android apps?

Is it possible to create one Django web app and also release iOS and android versions of that app without having to write in the native languages? It would be great to avoid having to learn/write in 3 frameworks but also is great for consistency/maintainability, only having to maintain the code in one place

Of course, a Django web app can be used on mobile, but people always seem to say that users want to actually install an iOS/ android app instead. What is the best option here?

Looking for someone willing to join a call with me to review my code

I'm working on Django Rest Framework and built REST API with MySQL workbench as database, I've got most of the code done, but I'm facing bugs in authentication that I've been stuck on for a really long time and I can't move on with my project without fixing them, I really tried everything and I'm trying this as a last option, I don't want anyone to write me code, I'm suggesting if someone is willing to join a discord call with me where I can share my screen and they can review my code and maybe tell me what I've been doing wrong. it's not a large project and I'll make sure I don't take much time, it'll be much appreciated, thanks for everyone in advance :)

We're thinking of rewriting our go / java API in python, what do we need to think about?

Background:
We have a horrible hodgepodge of APIs in front of our data platform, java that mostly calls underlying functions in the go (with slightly more user friendly calls). The go API often calls bash scripts to do the actual work. Most of the stuff the API does is building a call for an external service like doing spark submit on the file the user has provided or creating a table in hive with details the user has provided. The java API has swagger and is mostly what all users call.

One option we have is to rewrite it all in go getting rid of java and bash, write swagger into the go and all the things the java does.
But we're predominantly a python shop, which means whenever something needs to be done with the APIs only a few people are prepared to go near it and it's recieved very little change over the years where the rest of the platform is moving on rapidly.

So a few of us are in favour for rewiteing it all in something like fastAPI, (or maybe black sheep?)

From what I understand this would basically give us swagger for free and mean there

How can I incorporate data science in Django project?

Hello, I’m working on a data science project for academic research. I need to do some data analysis (I mean, data acquisition, pre-processing and data processing), specifically, it is about natural language processing so I also need to train a machine learning model I can get an output I can put in a map (a Google map).

I’ve selected Django as the back-end framework I will use together with Flutter to develop my user interface for a mobile app in which I can deploy my map.

So, my question is how can I handle my data analysis code into the Django project so I am able to map the output of my analysis into my geographic map, that is to say: where do I have to put my data analysis logic in the Django project considering I am planning to save the data I retrieve externally into a database based on my models? and, consequently how can I store the analysis into the database?

Somebody told me about using microservices but, is that really necessary? In which cases are they used? And, can I manage this locally or what approach should I use to manage this data processing? at what point would I
