Java REST api vs Django REST api for ML
It's been trivial thing for me!, and bugging me for over a 2 weeks. My Project Contains MVC in Java - Spring+Hibernate. I've been using Java for more than 4 years, so far it's good, but recent Machine learning bothering me so much because i just want to restart my 4 year old project in Machine Learning(It's best thing for my project, And i can't reinvent algorithm to match for my project). I read lot about Machine learning, I was so keen at Google TensorFlow, Sadly i can't use it in Java as i know, The API by google is not ready for Java.On the other hand i read about DL4J, it's seems okay but i have to explore it. On the Python side TensorFlow works flawless and SciKit too, but i'm new to Python Django REST framework. I'll quickly may catch up DRF. And it's seems that DRF is so light weight and pretty great without like spring annotation and hibernate annotation and too many stupid things. But one thing bothering so much is that will i stick to Java with DL4J or switch it to Python DRF? Please suggest me which track should i choose? Thanks -

Django Allauth Google Integration hangs and timesout on /accounts/google/login/callback
I am having some issues with my new Zappa Django app. What is weird is that I had this same code implemented on a different instance, and it worked fine. Now that I have just redeployed, I am getting an issue with my Google Oauth integration using Django-Allauth. I can access my login page fine, which redirects me to /accounts/google/login from which I can select my Google account. When I do that, it then hangs until the request is timed out. Here is the request log: [1542344053895] [INFO] 2018-11-16T04:54:13.895Z a9ff335f-e95b-11e8-b081-5b1d3f780ffe 136.24.233.181 - - [16/Nov/2018:04:54:13 +0000] "GET /login/ HTTP/1.1" 200 1928 "https://example.com/accounts/google/login/callback/?state=QkKCasdSut7aQasdO&code=4/lwBmAlt9asjdjasdYsgZirWPDkGTasd9asd9uw7OzFqMFjrlo7nzjA_knnE_Wuz_xQ-p4HtAZZOjdbJQyoToI&scope=email%20profile%20https://www.googleapis.com/auth/userinfo.profile%20https://www.googleapis.com/auth/userinfo.email" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36" 0/41.995 I've never had this issue, so I feel like it may be something with the social account setup, but it seems to mimic my previous configuration.

Access django celery results in views
I'm using the django-celery-results extension and successfully saving records in the db backend table, celery_results_taskresults. My tasks are associated with model instances, and I want to be able to list them as attributes of each instance, in views and ultimately templates. I can see them in the admin interface, but can't figure out how to access them in a list. I though of creating an @property on the model in question, using raw sql, but the sql examples I've seen all refer to a model, and if there's a celery_results_taskresults model, I can't find it. -
Django vs Flask?
I'm working on a university project and trying to decide which framework would be better for us (group project). Here is the info about the project and the members that are of note: Group project (3 of us) due in 2 weeks Need to design a user interface for our database server (website backed by DB) MySQL was used for database design We all have fairly decent python experience (and I'd like to think we are all capable people, willing and able to learn - even in this short amount of time) We have little to no web development experience I know there are plenty of differences from what online (although both would work). I may be wrong, but I think the most important factor for us would be which framework allows us to work and connect to MySQL most easily. Thank you so much to people who answer, it will be super appreciated! -
Django compress error: Invalid input of type: 'CacheKey'
We suddenly started getting this issue when compressing django static files on production servers. Ubuntu 16.04, Python 3.x, Django 1.11. I am using an ansible-playbook to deploy. The error is as follows: Invalid input of type: 'CacheKey'. Convert to a byte, string or number first. It doesn't seem to be an issue in one of the static files but a general issue. Every time we run it, we get a different file. I was looking for any clues on google and nothing shows up with the same error. -

Dango: Internet Explorer POSTs an empty form
