kandi X-RAY | PEDRA Summary
PEDRA is a programmable engine for Drone Reinforcement Learning (RL) applications. The engine is developed in Python and is module-wise programmable. PEDRA is targeted mainly at goal-oriented RL problems for drones, but can also be extended to other problems such as SLAM etc. The engine interfaces with Unreal gaming engine using AirSim to create the complete platform. Figure below shows the complete block diagram of the engine. Unreal engine is used to create 3D realistic environments for the drones to be trained in. Different level of details can be added to make the environment look as realistic or as required as possible. PEDRA comes equip with a list of 3D realistic environments that can be selected by user. Once the environment is selected, it is interfaced with PEDRA using using AirSim. AirSim is an open source plugin developed by Microsoft that interfaces Unreal Engine with Python. It provides basic python functionalities controlling the sensory inputs and control signals of the drone. PEDRA is built onto the low level python modules provided by AirSim creating higher level python modules for the purpose of drone RL applications.

QUESTION
I have a .txt file that has the data regarding the total number of queries with valid names. The text inside of the file came out of a SQL Server 19 query output. The database used consists of the results of an algorithm that retrieves the most similar brands related to the query inserted. The file looks something like this:

QUESTION
Basically i want to make a program in python that, given a list of words and a list of letters, it will print out a list with only the words that don't contain any letter in the list of letters.
...ANSWER
Answered 2021-Mar-15 at 10:48.remove doesn't return a new list with the item removed, it removes it inplace and returns none
Instead, start your final list as a copy of the original and then just remove without assigning to a variable
QUESTION
I'm trying to display a custom dialog but it's not showing up but making the background transparent. The weirdest thing is that when i change just the custom dialog xml it shows up without problems so i think it could be the xml but i've been looking for a while and i can't find the problem.
This is the fragment code:

Answered 2021-Feb-18 at 11:18I had the same problem too and it was because I was using 0dp in ConstrintLayout in order to using match_constraint size but it's not working in dialogs.

QUESTION
So, I have this little project of Rock, Paper and Scissors for learning (specifically using Tkinter to create a GUI) and I'm stuck with a counter. I have already checked in Python terminal that the counter is working, but it's not updating the Label so the counter is stuck in 0 in the interface. I tried everything and searched for other programs like mine and they did the same thing, I simply don't know what to do. Could anyone solve that for me? (The code is a little over extensive, sorry for that. Also some texts are in portuguese, but I think it doesn't really matter.)
...ANSWER
Answered 2020-Aug-29 at 07:41Your label is not updating because you haven't connected it to any text means it doesn't know what text to show on change. You can use StringVar() what it does is it automatically updates label whenever text is changed.
QUESTION
I am trying to solve my problems making searches, reading documentations.
The problemI want to get all youtube titles from an youtube channel using python beautiful soup. Youtube loads dynamically, i think with JavaScript, without pyqt5 I just can not get any title, So i used the pyqt5 I was able to get titles from youtube channel. The problem is that i need to load all the videos. I can just load the 29 ou 30 first ones. I am thinking on simulating a scroll down or somthing like that. I can not find how to do this on beatiful soup without selenium...
Version and libraries used:- Python 3.7.4
- BeautifulSoup4
- riverbankcomputing.com
- I want to understand what i can and what i can not do with BeautifulSoup on dynamic pages.
ANSWER
Answered 2020-May-25 at 21:58As you point out you have to scroll down until the "spinner" does not appear but for this you need to use a QWebEngineView, and then you can get the text as you have done or use QWebChanel as I implement it in my answer. So that the QWebEngineView is not shown I have activated the attribute Qt::WA_DontShowOnScreen.
QUESTION
Requirement: I need code a Jo-Ken-Pô game which can be played with multiple players. There are 5 roles (SPOCK, scissors, paper, stone and lizard). I can accomplish it with these two chainned when/switches (the code bellow uses when() because it is in Kotlin but same idea can be applied using switch in Java)
...ANSWER
Answered 2020-Apr-28 at 09:27This switch inside switch construction looks really hard to read, you're right.
Think of it this way: each PlayType wins from some others. And this information look like a configuration, so can be described in a declarative way, like this:
- SPOCK wins against TESOURA & PEDRA
- TESOURA wins against PAPEL & LAGARTO
- etc
So you can just define a Map> and verify if u2.play is contained by map.get(u1.play)
UPD. Code example (java, written in notepad, so may contain some syntax mistakes)
QUESTION
I'm trying to do a chloropeth map following this guide: https://www.r-graph-gallery.com/327-chloropleth-map-from-geojson-with-ggplot2.html
I mixed a bit of the tutorial with this answer(Chloropleth map with geojson and ggplot2), since I wasn't getting the result I expected. The cities were being filled with the same color, and it seemed as R wasn't understanding the data as numeric, and filled every city that had at least 1 user with the default color. (tried using as.numeric, didnt work either)
I downloaded "users by city" data from my website from Google Analytics using
...ANSWER
Answered 2020-Jan-28 at 22:09It looks like you have a couple relatively large values, while most are small. This causes 'skewing' of your color scale in a way that looks less interesting. Instead of graphing number of users, consider mapping based on a quantile .
Here is an implementation of grouping into quantiles using cut2() from Hmisc. In this case, values are cut into 5 groups.
