I have a very large Pandas DataFrame with 28171643 rows and 4 columns. A subset of this DataFrame for one day is shown below.

My task is now to calculate the total amount for pair for each day. The days range from 90 to 320. Please note that (as the name says) the reversed column always contains the flipped tuple from column pair in each row.

Here an example:

Row 0, 1, 2 and 4 all contain the same tuple combination, wether it is in column pair or reversed and therefore need to be sum up to 5+17+1604+1558 = 3184. Ideally this information is than stored in a new DataFrame with columns day, amount and tuple. It does not matter if tuple contains the value from pair or reversed as the combination is not directed.

I have a solution show below, but this takes way too long for this huge dataset! As hardware I have a workstation with 48 cores 186GB RAM and a Quadro RTX 8000 GPU. If there is an easy solution with Dask for example or rapids.ai this is totally fine!

My slow approach on a day-basis:

If there is a way to parallelize this, it would also help!

I want to make a hash of hash using the structure of an array. Each array element should be a subkey of the preceding array element. For example using the following arrays:

My query deletes the whole table instead of duplicate rows. Video as proof: https://streamable.com/3s843

The best way I can describe what I'm trying to do is "Nested DistinctBy".

Let's say I have a collection of objects. Each object contains a collection of nicknames.

I am having difficulty getting Ansible to perform logging. A simple YAML named demo5.yml spins up AWS EC2 instances (below). The following entry has been added into the ansible.cfg file: log_pth=/var/log/ansible.log

The playbook YAML is executed by calling: ansible-playbook demo5.yml -v

There is nothing in the ansible.log after execution.

What am I doing incorrectly?

I have a package, s3_backend, which contains a module api.py, and a subpackage util, which itself contains 5 modules. I would like to package it up and upload it to PyPI so people can pip install package and use the scripting api, api.py, in the top-level package. Both packages (s3_backend and 's3_backend.util') include _init__.py files.

The whole project is held in a directory names project with the following structure

I am doing back-end data input verification with amp-form and I want to display the errors on the front-end. However, when I submit the form, even tho the form contains errors (no name inputted) the front-end says "Success!" instead of outputting the errors.

I am having an issue creating a config file for a class that includes a list of objects that implement the same interface when I use the YamlStream API.

I want to preserve the local tags that I put on list items so that they can be deserialized correctly from another context. In my actual project, I have to do some pre-processing on the YamlNodes. However, when I want to serialize the YamlDocument to a file, the local type tags are lost. I see that the tags are parsed when converted to a YamlStream (some nodes have the Tag property set appropriately). However, after processing, they are serialized without the tags.

I have some examples of what I have tried in this repo: https://github.com/mariotee/YamlDotNetIssue

Edit: I have made it work by getting the target.value from the list, passing that to firstComp.js. Where the onChange method is below, but is this the best practice?
