Deploying tensorflow linear classifier pretrained model to web server using Flask

Hi,

I'm having an issue with deployment of a Flask app that uses a tensorflow model to make predictions on data provided by a user.

The code works fine in a local environment, but fails silently when pushed to my web server.

The code I'm using is functionally the same as the code in this tutorial: https://www.tensorflow.org/tutorials/estimator/linear

This is the output locally: https://gyazo.com/041dacfa584832f109cbf5b1fd09f0a8

edit: on the web server it simply can't load any pages. They seem to timeout - no internal server error or anything.


Which normally means a function can't be found.

​

It seems to be silently failing - I can't find a log in my ubuntu machine being useful to me.

Deploying Flask app using Procfile and .env file with Postgres

I am trying to deploy my Flask app to a VPS installed with Dokku. I don't have much knowledge in regards to Docker deployment, but Dokku seems to pull it all together using Herokuish. However, I am having some difficulties pushing my app to my Dokku instance.

My directory/file structure looks a little something like this:

.env
run.py
Procfile
requirements.txt
config.py
spotifyproject
│ init.py
│
└───api
│ │ spotifyhandler.py
│ │ spotifyclient.py
│ │ spotifyauth.py
│
└───user (user login/signup routes & db handling)
│
└───models (user & like models)
│
└───profile (routes for displaying content from /api)

Then in some of the files:

# Procfile
web: gunicorn spotifyproject:run

# spotifyproject/init.py

For any pandas users, I just finished adding a full UI for merging & stacking dataframes to free pandas visualizer

​

Merging & Stacking in D-Tale 1.35.0

I recently added the ability to merge & stack (vertically concatenate) dataframes in my open-source Pandas Dataframe Visualizer, D-Tale

Feel free to play with the demo here

This recording is a demo of the new "Merge & Stack" feature of D-Tale. You'll see the following:

Editing of parameters to either a pandas merge or stack (vertical concatenation) of dataframes (and viewing examples from the pandas documentation)
Selection of dataframes & viewing the data within them after selection
Uploading of additional dataframes from an excel file
Viewing python code snippets & resulting data from a merge or stack

D-Tale is available on both pypi & conda:

`pip install dtale`
conda install dtale -c conda-forge

Please let me know if theres anything else I can do to make this functionality better and support open-source by tossing your star on the repo. Thanks!

Should I use Django for this project?

Hi all. I'm decent at python, decent at html (neither one is my job, programming is a hobby and eventually maybe more). I keep using programming to build things I actually use. Here's my website I plan to make, I'd like to get a quick "Yes, do this in Django" or "oh god no, thats not what this is for, go use XYZ".

​

I'm teaching a class for 6 months, all online. I want to build a website for the class. My initial thought is

​

Google to login (nearly everyone has this). can't get past the landing page without being logged in. I'm being paid separately(not by each person), so if extra people join it doesn't really matter.

Landing page with a bit of "this is what is here"

each week of the class has its own page, like a blog post.

each post has

\- required reading

\- link to the zoom meeting. This would go dark after class is done for the week

\- link to the YouTube recording. This would be added after the video is uploaded.

\- An email the instructor (me) form.

\- Link to the practice test for that chapter.

\--- I need a testing

Understanding the Flask WTForms validation popup

Hello, this is my first post in this forum please don't be rude thank you :)

I'm currently having a hard time understanding and especially styling the "Form Validation Error Message" or whatever you call it.

TL;DR:

How is the popup from the picture attached displayed, and how can I style it with CSS?

Most approximate Stack Overflow thread I found: Link (didn't help me)

​

Validation Popup

​

Long story with explanation:

I made a sample application with Flask-Security-too, SQLAlchemy, Flask-Mail, WTForms and all this cool stuff (this is not the first time I'm using Flask)

On the Picture is a sample Form that consists of 2 inputs, a title, which is required and a text, which is not. If you try to save this, it's displaying this popup kinda thing that says it can't be empty.

Everything is good till here, because I don't even know how this is rendered? I removed every macro that renders errors and blocked every possible JavaScript function. It is still able to render a popup without a page reload. (The HTML is clean, there's nothing that shouldn't be there).

Can anyone explain this to me? I'm reading the source code right now, and I can't really find something there either...

And maybe also how this

META What happened to r/Python?

I've not been on r/Python in quite a while because life. I visited daily maybe 12-18 months ago and I remember the content here was a lot more discussion about the language itself, with a few pandas and datascience tutorials sprinkled in. Many threads had long discussions that were interresting to read.

Now it seems 90% of posta have less than 3 comments and the posts are mainly beginner showcases (that nobody cares about judging from the amount of comments they get) or some youtube tutorial about machinelearning or building a twitter/discord bot in 4 lines og python.

Is it just me or has this community changed a lot during the pandemic? r/Python used to be the fist thing I checked out on reddit. Not so much anymore unfortunately.

Using JWT to authenticate Flask API. I am almost done but having some issues. Can someone please help me?

I am trying to implement JWT authentication for a Flask API. I am using flask_jwt_extended. I am confused about how to persist user sessions. My API has an endpoint for login which issues an access token. I have a different resource that refreshes the token. So, how do I implement the functionality where after the access token is expired, the user is automatically issued a new access token without having to log in.

My current logic ( I believe I am missing something). After a client sends an access token and gets the response that the token is expired, it sends the refresh token to TokenRefresh resource to get a new access token and then resends the same access token. Kinda seems like a bad design. How do you guys suggest I do it?

Resource for Token Refresh

class TokenRefresh(Resource):
@jwtrefreshtokenrequired
def post(self):
currentuser = getjwtidentity()
accesstoken = createaccesstoken(identity = currentuser)

Managing the version of a Flask app

I am looking for some guidance on managing the version number of my flask app. Its currently just a variable that is displayed at the footer area of the app but I want it to be more useful, such as in a way that it can either be auto-incremented through my CI/CD pipeline or perhaps something like a pre-commit hook to remind me to increment it before pushing code up.

Twitterbot Python Code

I wrote a twitter bot to get a million followers on Twitter

by following hundreds of thousands of people, awaiting the follow-back, and automating unfollows after a certain time period. Rate limits immediately stumped my ambitious ideas. In hindsight it may have been a bit too ambitious.

Watch how I made it: https:\/\/www.youtube.com\/watch?v=-ZsWwbwhy6g&feature=youtu.be&ab\_channel=DylanSmith

So I remade a reddit-like posting page with a twitter bot by listening to the twitter-post stream and scraping all content in tweets made mentioning "@bestpostbot", "#bestpostbot", or simply "bestpostbot" and posting them on my bots page.

Essentially, anyone can make a post on this page by tweeting their own post and just mentioning the bot. My bot's page (https://twitter.com/bestpostbot) then serves as a space everyone can browse collectively for interesting content. "Upvote" your favorites.

The tweet with the mosts likes and retweets gets pinned and shown off at the top, while all posts on the page compete for this spot. Welcome to bestpostbot. Make a tweet.

Java programmer coming to Python for the first time...

Decided to try and do a thing in Python for the first time in a while.

Wrote a small program to test out a library in Python that I'd originally been using the Java version of.

Keep in mind I'm very, VERY used to Java and to an extent C++.

Take a guess as to what happened.

​

It ran flawlessly with zero errors the first time I ran it.

​

Why the hell don't I use this friggin language more often.

I'm genuinely still astonished, not a single thing I've made in Java has run flawlessly the first time I run it.

So uh, hello Python. Where the hell have you been all this time?

How to Read and Remove Metadata from Your Photos With Python

My latest article for the Auth0 blog shows you how to use the exif module to find all sorts of interesting information encoded in the digital photos you take: Where they were taken, which direction the camera was facing, what altitude the photo was taken at, and even the speed at which the photographer was moving! It also shows you how to alter and erase that information.

Where, when, and at what altitude was this photo taken? Python and the exif module can tell you.
