Cannot get url parameter to work in Django - django

Question

I am trying to pass a parameter through the url in Django, but nothing seems to be working.
This is my views.py:
from django.shortcuts import render
def show_user_profile(request, user_id):
assert isinstance(request, HttpRequest)
return render(request, "app/show_user_profile.html", {'user_id': user_id})
This is currently my urls.py:
urlpatterns = [
path('', views.home, name='home'),
path('profile/', views.profile, name='profile'),
path(r'^show_user_profile/(?P<user_id>\w+)/$', views.show_user_profile, name="show_user_profile"),
path('admin/', admin.site.urls),
]
I've tried
http://localhost:50572/show_user_profile/aaa
http://localhost:50572/show_user_profile/aaa/
http://localhost:50572/show_user_profile/aaa//
http://localhost:50572/show_user_profile/?user_id=aaa
but I always get that same screen saying it can't find the url pattern.
But I've tried, all failed.
And neither does this:
path('show_user_profile/<int:user_id>/$', views.show_user_profile, name='show_user_profile')
This doesn't work either, by the way.
path(r'^show_user_profile/$', views.show_user_profile, name="show_user_profile"),
I've looked at the answers here and here, and I seem to be doing everything right. What am I missing?
EDIT:
Here's my show user profile template:
{% extends "app/layout.html" %}
{% block content %}
{% if request.session.uid %}
<div id="profile">
<div>
<span id="profile_prof_pic_content">
<img id="prof_pic" src="{{ user_data.prof_pic }}" width="100" height="100" />
</span>
<span>
{{ user_data.first_name }} {{ user_data.last_name }}
</span>
</div>
<div>
{{ user_data.prof_desc }}
</div>
</div>
{% else %}
<h2>You are not signed in. Log in to access this user profile.</h2>
{% endif %}
{% endblock %}
{% block scripts %}
{% load static %}
<script src="{% static 'app/scripts/jquery.validate.min.js' %}"></script>

Instead of this:
path(r'^show_user_profile/(?P<user_id>\w+)/$', views.show_user_profile, name="show_user_profile"),
Try this:
re_path(r'^show_user_profile/(?P<user_id>\w+)/$', views.show_user_profile, name="show_user_profile"),
And try to navigate on browser
Note: I have used re_path instead of path. you can check here
