simplest Python WEB app for implementing neural networks

 Making a machine learning app is not enough by itself.  You have to package it and SELL it, or present in a commodity form.  This is an example of a simplest WEB app that can be changed to run a neural network PREdICT command on the WEB.

 

Open the POWERSHELL app (from ANACONDA)

First, make sure you have Django installed. You can install it using pip:

pip install django

pip install django

Create a working directory:  C:\Users\ars\ARStensorflow\0icron\interactive

django-admin startproject myproject

cd myproject

python manage.py startapp myapp

This creates:



Now, let's define the view for our web application. Open the file myapp/views.py and add the following code:

from django.http import HttpResponse

 

def index(request):

    return HttpResponse("Hello, welcome to my Django web application!")




Views are here:


Next, we need to define the URL pattern for this view. Open the file myproject/urls.py and add the following code:

from django.urls import path

from myapp import views

 

urlpatterns = [

    path('', views.index, name='index'),

]

Now, we have defined the view and URL pattern for our application. We just need to configure the Django project to use our new application. Open the file myproject/settings.py and add 'myapp', to the INSTALLED_APPS list:

INSTALLED_APPS = [

    ...

    'myapp',

]

Urls and settings are here:


 

Finally, run the development server using the following command:

Run it from POWERSHELL that you had opened in the beginning.

python manage.py runserver

 

Now, if you open a web browser and navigate to http://127.0.0.1:8000/, you should see the greeting message "Hello, welcome to my Django web application!" displayed on the page.

The screen outputs:





Simplest Python interaction app for neural networks

 Making artificial neural networks is not enough by itself. You have to package them in a standalone application like Qt or a Web application. Here is the simplest (working) Python Qt app:
