How does a beginner learn Machine Learning?

I usually use R for my work and have a tiny bit of experience with Python. What's the best way for me to go about getting Python under my belt with the goal of mastering basic concepts in machine learning?
Specifically, I'm asking for suggestions in online courses, but also how should I think about this? Any advice is welcome. Thanks!

Trying to get a template/link working in Mezzanine

Hey all,

I'm working on a Mezzanine project. I made a `ProjectLinkPage` class that inherits from Mezzanine's Displayable class. I logged into the Admin section and added a `ProjectLinkPage` object with the slug "some-content." I want to open the template `some-content.html` by going to "http://127.0.0.1:8000/projects/some-content." This does not work. I get a 404 error.

Here's how my directory looks.

myProject/
- myProject/
-- urls.py
- theme/
-- models.py
-- views.py
-- templates/
--- pages/
---- project_pages/
----- project_base.html
----- projects/
------ some-content.html

My `models.py` looks like this:

class ProjectLinkPage(Displayable)
# Fields and `class Meta`, etc...
@models.permalink
def get_absolute_url(self):
return ("project_detail", (), {"slug": self.slug})

`views.py`:

def project_detail(request, slug, template="project_pages/project_base.html", extra_context=None):
project = get_object_or_404(Project, slug=slug, status=2)
context = {
"project": project,
"editable_obj": project
}
context.update(extra_context or {})

templates = [u"project_pages/projects/%s.html" % str(slug), template]
return TemplateResponse(request, templates, context)

`urls.py`:

`url("^projects/(?P<slug>.*)%s$" % _slash, project_detail, name="project_detail"),`.

Have I missed something in these files? What must I change for my browser to correctly locate the `some-content.html` template when I go to "http://127.0.0.1:8000/projects/some-content?"

User Authentication

Hi everyone. I am new to Django, but I have a question about user authentication. I understand that Django has a built-in authentication service, but I would like to implement another user authentication service. Are there any good resources for implementing third-party user authentication services. Also, do you guys have any recommendations?

No error but css effects not taking place

I am loading two static files into my HTML code, "animate.css" and "home.css".
For some reason the animate.css effects do take place when I go to the page on my localhost, but the home.css effects do not.

I am not getting a specific error message though. My terminal says this: https://imgur.com/a/BPJZ1
I don't see a specific message that it is getting the home.css file, while I do see a specific message that it is getting the animate.css file.

my code looks like this: https://imgur.com/a/QBXVT
does anybody have an idea why the home.css effects aren't taking place when I go to the page linked to the home.html file ?

User Flow of multi tenant app using django tenant schemas

So I am confused how to handle user schema in django tenant schemas, I want user to sign up and then create their tenant, so i put django.contrib.auth in shared_apps, but that gave the users access to other tenants, so can anyone recommend the ideal way to handle this.

Dynamic page - Views/Templates

A view:

> def index(request):

> url = request.get_full_path()

> url = url.split('/')

>

> ''' url = ['', index , ''] '''

>

> page = 1

>

> '' bla bla ''

>

> if request.full.path[-1] == 'up':

>
> page = page +1

> else == request.full.path[-1] == 'down' and page = page -1.. bla bla

>

>

And the template:

> <a href="whatever/*{{ page }}/up" class='next'> Up </a>

> <a = href="whatever/*{{ page }}/down" class='previous'> Down </a>
>

Now, yeah, it works, until up the point i have to switch the page back or forward, when i get a bug where the last page variable value is rendered before i can get the last section of the buttons's URL's especifying if it's either "down" and page = page -1 or "up" so we go page = page + 1 and to the next page...

What happens then is that the first time i press "Down" after pressing "Up", i still get a positive page count, only from the second time on it works properly in the right direction..

I know it sounds kinda of a no brainer but i'm seriously having trouble thinking of anything quick...

Trouble with jQuery and flask

Hey guys, not sure if this is the best place for this question. I'm still fairly new at flask and have had a bit of trouble finding what I'm after with a bit of google-fu.

I have a multiple select list on a page within my flask app, using jQuery to dynamically filter the results based on what the user has typed so far [shamelessly pinched from this resource](http://www.lessanvaezi.com/filter-select-list-options/). When I load up the html file on its own, it works fine, but when I actually run the app in flask, it doesn't work! I can only think I've got some of the html in the wrong place, causing flask to not load my jQuery at the right time (or so I've gleaned by my searching). If anyone can help me out, it would be much appreciated. I won't bother pasting my flask code below, its your basic first app type of thing which just uses render_template to load the html.

Coding text editor for remote server ?

Hi,

I am looking for a text editor to write python code on an amazon server that is not VI/VIM/Nano. I am currently using vim , but I find Komodo much easier to read from. To get to this server I must pass an intermediary server if that makes a diff. I want to be able to edit the scripts I have on the server using a text editor like Komodo Edit or something - without having to upload the changes to the server from my local machine each time.

Hope that makes sense.

Thanks

EDIT:
Didn't realise I could make VIM 'nicer' - Ill just use this : https://realpython.com/blog/python/vim-and-python-a-match-made-in-heaven/#vim-extensions

JQuery/Ajax to call a server side function?

I am having some difficulty with the syntax to actually call a python(server side) function from a button on my html page.

I have an html table with a button on each row. I understand the concept of making a call back to the python application to run

def somefunction(someVarFromTable):

Which is located on my app.py file for now.

But the syntax of JS is throwing me off. Any resource recommendations? Thanks

EDIT:
Apprently I did NOT have a firm grasp of the concept. I was able to meet my needs by calling a {{ url_for(somefunction), someVarFromTable }} on button click and then redirecting back to my updated table.
