Depending on what you are trying to train on (not considering the data and goal). Your first start is to not use big resolution of the images. Just start small (256x256 or 512x512). All you need to do is to resize the images first (use opencv to resize) Then train the model on that. It will surely give you (and the hardware) some breathing room.

Time Picker not closing when pressing cancel

Asked 2021-Dec-18 at 18:07

I'm writing a To-do application for a hackathon I'm taking part in. I'm implemented a time picker in a pop up but as soon as I press the cancel button on the time picker it doesn't close at all. Any reason why this might happen, I tried setting an onCancel but that doesn't seem to work. I can't find any information on how to close the picker when I click cancel in the documentation.

...

ANSWER

Answered 2021-Dec-18 at 18:07

The onCancel is calling setModalVisible but the picker doesn't seem to be part of the modal. You should have onCancel={() => this.setState({showDate: false})}

EDIT

Given you're update, you need to pass the event and date attribute from the onChange handler:

Create sqlite database once on startup

Asked 2021-Dec-18 at 06:58

I'm working on a hackathon for my local college and its my first time working with react native, I have some measurable skills in react and I want to learn new things, now I want to create a database table when a "landing page" is opened, it works, just not the way I want to. I want to create the tables once and if they exist I don't want anything to happen, but they get overwritten and then records are cleared each time, which creates frustration in order to create an account over and over again. I want to start integrating the database with my frontend and finish on the application but I'm stuck on this issue. Any ideas

ANSWER

Answered 2021-Dec-17 at 19:39

If this is your actual code then there is no way to overwrite the tables because you are using IF NOT EXISTS in the CREATE TABLE statements.

A problematic part in your code is this query:

QUESTION

Connecting an AWS Amplify frontend with a EC2 instance?

Asked 2021-Nov-11 at 01:24

So, I'm working on a hackathon project right now, and for the demo, I've spun up a NodeJS Express server on an EC2 via Elastic Beanstalk. When testing the server's API with our front-end locally, it worked perfectly fine.

Now we've deployed our front-end to AWS Amplify, setup a domain name in Route53, and hooked everything up. When we go to the domain, our front-end looks great, but when we try using the functionality that would connect to our server's API, we get a net::ERR_SSL_PROTOCOL_ERROR.

Doing some research, it looks like(?) that we have to setup a certificate on the Classic Load Balancer that's in front of the EC2. So I requested a certificate, and created a listener on the Load Balancer as follows:

Load Balancer Protocol Load Balancer Port Instance Protocol Instance Port HTTPS 443 HTTPS 3000

But now I realize that if setup this way, I still have no idea how to point the React Frontend's API calls to the Load Balancer instead of the EC2, or whether the listener is setup correctly. Would anyone have an idea of what steps we should take here?

For the details of the app, the backend is a pretty straightforward Express App with CORS enabled, and the frontend is a fairly standard React project, nothing special about either of them.

Instance Protocol should be HTTP. So your setup uses HTTPS only between client and CLB:

Well, first of all and regarding SSL (since it's the first thing that you mention) you need to configure it using the certificate and listen on the port 443, not port 80.

With that modification, your Proxy configuration would already change to:

I am creating a newsletter subscription API with node.js and typescript. And I'm using typeorm and PostgreSQL for the first time. Where I configured typeorm and built the entity types as described in multiple tutorials I found.

Yet I keep getting the following error for the semicolon after all the columns/attributes in each entity.

To my surprise, the error traces back to the build js code in the dist folder, not the source typescript code.

How to save celery task to a temporary db which will then be updated to the master db

Asked 2021-Sep-20 at 09:55

What is a good way to compare new data with old data which is updated everyday with Django ORM? Basically I have a scraper which fetches hackathons everyday (basically just a celery task) and I want the newest to be unioned it with my master database which has the latest fetched hackathons from yesterday. I don't want to destroy my master database and then just upload everything that I just fetched since that seems wasteful.

...

ANSWER

Answered 2021-Sep-20 at 09:55

This more seems data comparison and no need to save celery task in db. Ideal use case to save celery task in db is when that task it self needs to be scheduled.

For data comparison you can make use of hash (MD5, SSA1 etc). This will speed up the data comparison.

for existing records in db, create one column to store hash of that entire record. use algorithm of your choice MD5, SHA1, SHA224, SHA256, Snefru etc to hash.
when new data is received/processed by celery task, create a hash of that record too.
now compare this hash created in 2nd step with hash of all exiting records.
if there's a match found then data already exists in master.

QUESTION

Celery periodic tasks being processed only if a post and get request is sent to a route containing .delay() and AsyncResult()

Asked 2021-Sep-11 at 01:43

I want to run this task for every three minutes and this is what I have

tasks.py

...

ANSWER

Answered 2021-Sep-11 at 01:43

What we know is that:

Your Django app is running because it can accept the GET / POST requests
- e.g. python manage.py runserver
Your Celery worker (consumer) is running because it can accept the asynchronous .delay() requests from the Django app
- e.g. celery --app=my_proj worker --loglevel=INFO

Possible Solution 1

Check if the Celery scheduler (producer) is also running.

e.g. celery --app=my_proj beat --loglevel=INFO

Unless you embed the scheduler to run inside the worker, take note that they are different entities. The worker a.k.a the consumer is the one that will receive/process the request, while the scheduler a.k.a the producer is the one that will send/trigger the request. Without a running scheduler, of course the scheduled tasks wouldn't be enqueued thus no processing would happen.

More info with running the scheduler here.

Possible Solution 2

Check for error logs in the worker instance (the consumer). Probably, the scheduler (the producer) is running and enqueues the task but the worker fails to process them, perhaps due to the task implementation isn't found. In that case, make sure to include the location of the task in the celery app's configuration e.g. celery_app.conf.update(imports=['backend.tasks']).

To verify if the scheduler is running correctly, the logs must show that it correctly enqueues the task every 3 minutes:

QUESTION

Algorithm to check whether students can be allocated to classes as per their preferences

Asked 2021-Jul-19 at 09:02

In a coding hackathon I got following problem :

There are K classes each having certain capacity. There are N students and each has one or two class preference. We need to print "YES" if all the students can be allocated to a class or else "NO".

For example :

...

ANSWER

Answered 2021-Jul-11 at 10:17

You can create a bipartite graph with student nodes on one side, and then on the other side create class*capacities nodes. Each node represent one spot in a class.

An edge from a student to a class node represents that this student is willing to take this spot. Note that a student is willing to take any spot in a class it has a preference to.

The problem then is to find a perfect matching in this graph. If such a matching exists it is a "YES", if not it is a "NO".
