excalibur | A web interface to extract tabular data from PDFs | Document Editor library

I totally I don't have knowledge to create scripts but with internet help I made something like this:

Say I have many similar pdf files as the one from here:

I woudld like to extract the following table and save as excel file:

I'm able to do extract table and save excel file manually with package excalibur.

After installing Excalibur with pip3, I initialize the metadata database using:

$ excalibur initdb

And then start the webserver using:

$ excalibur webserver

Then go to http://localhost:5000 and start extracting tabular data from PDFs.

I wonder if it's possible to automatically do that with python script for multiple pdf files with packages such as excalibur-py, camelot, pdfminer, etc, since the size and position of table are fixed for same city's reports.

You may download other report files from this link.

Many thanks at advance.

I have a problem about implementing recommendation system by using Euclidean Distance.

What I want to do is to list some close games with respect to search criteria by game title and genre.

Here is my project link : Link

After calling function, it throws an error shown below. How can I fix it?

Here is the error

I am building a system to allow our clients to transform PDF bank statements (from many different banks) to its better CSV form (better because it can be imported into accounting application). It will find tables on PDFs pages and convert them into CSV files.

I am going to use:

1. Simple static webpage with HTML form to upload PDFs and choose which bank to process. It will also display job status and allow to download result of the transformation (CSV files). It should operate without user authentication.
2. Backend running on NodeJS (more on that later)
3. Excalibur
4. Puppeteer (to operate Excalibur)

The Backend has to take responsibility for:

1. Receiving request from the UI (PDF payload)
2. Generate new job id
   1. sending it back to UI
   2. provide HTTP resource for UI to ask for job status
3. Make new instance of Puppeteer, pass to it received PDF and job id
4. Wait for Puppeteer to finish, receive archive file (Excalibur puts every page of the table in a separate CSV file)
5. Unpack archived CSV files
6. Normalize it with transformers (written with https://www.npmjs.com/package/mississippi)
7. Send response to UI (client)

Problems that will occur:

1. Multi-tenancy - multiple users at once will access the system (I am used to PHP which runs in context of a one user session, and I know that NodeJS resides in memory, going to resolve it with 'continuation-local-storage' package)
2. Communication FE<->BE, there is a challenge with processing of big PDF files (it will take a lot of time) and giving feedback to user. That's why I need some sort of job id to recognize clients.
3. Disabling Excalibur database - my solution does not need to save any state.

As You can see there is quite a lot of things to do. I do not want to discuss decisions (eg why Puppeteer and not direct access to Excalibur API). This is rather the first, crude version. I have plenty of ideas to improve this system later.

My question is: Should I use message queue system or not to simplify (make it more readable) this system? How could this system benefit from using such queue like AMQP or Azure Queues or simply MongoDB as a queue? How a simple design (block diagram) of such system could look like when using message queue? I have no previous experience with message queues, I never used them, but I feel message queue could help me design better structure of this system.

I am trying to parallelise these recursive functions with openMP tasks,

when I compile with gcc it runs only on 1 thread. When i compile it with clang it runs on multiple threads

The second function calls the first one which doesn't generate new tasks to stop wasting time.

gcc does work when there is only one function that calls itself.

Why is this?

Am I doing something wrong in the code?

Then why does it work with clang?

I am using gcc 9.3 on windows with Msys2. The code was compiled with -O3 -fopenmp

Ive been trying to instantiate a genserver process that will subscribe to PubSub in Phoenix framework, these are my files and errors:

config.ex:

This is my component file, when I show event object property it is not showing any on UI. somebody get their time to resolve the issue as I am a newbie into angular and project in the production.

I'm having issues where my website will cut off all information at the bottom of the screen and not scroll when at smaller aspect ratios. It will show the image no matter what but will cut the text below it. I have tried using overflow-y and overflow but neither allow scrolling. I'm not sure if it is due to elements being fixed or not but having the elements fixed is the only way I've been able to get them to look right.
