QUESTION
I am creating a scene in three js with two models in .glb format; I am following a pre-recorded class and I have followed exactly all the steps. We create a class for the models in model.js and in index.js we define them. Everything was working fine until from model.js we created a material for the models and it only loads in one of them. I have checked everything, searched for similar answers here and I can't find the error because everything seems to be fine.
This is model.js (the class)
...ANSWER
Answered 2022-Apr-04 at 16:22I'm also a Three.js novice, but it looks like DracoLoader loads a geometry
not a mesh so the way you're crafting your model might be causing the issue. Does instantiating a new THREE.Mesh with the downloaded geometry and material fix the issue:

I'm a Scrapy enthusiast into scraping for 3 months. Because I really enjoy scraping, I ended up being frustrated and excitedly purchased a proxy package from Leafpad.
Unfortunetaly, when I uploaded them to my Scrapy spider, I recevied ValueError:
I used scrapy-rotating-proxies to integrate the proxies. I added the proxies which are not numbers but string urls like below:

Answered 2022-Feb-21 at 02:25The way you have defined your proxies list is not correct. You need to use the format username:password@server:port
and not server:port:username:password

QUESTION
I am trying to save historical context data in Mongo, but without success. Only the first payload sent to Draco is saved to MongoDB for historical data, but Mongo does not react to attribute updates. Versions used for the test: Orion-LD version 0.8.0, Mongo version 4.4, Draco version 1.3.6. I tested it also with the 3.4 version of Mongo and the behavior is the same.
Can you, please, help me to fix a problem?
Below are the steps I performed:

Answered 2022-Mar-04 at 10:35We do not use that precise stack, but we have got many production deployments keeping context historical data on MongoDb by using FIWARE Orion (v2 API) with FIWARE Cygnus (NGSIMongo Sink for historical raw data, and NGSISTH Sink for aggregated data at MongoDB).
Maybe this help.
QUESTION
Here are the rules to my assignment: You have access to a database of student_scores in the format of a dictionary. The keys in student_scores are the names of the students and the values are their exam scores.
Write a program that converts their scores to grades. By the end of your program, you should have a new dictionary called student_grades that should contain student names for keys and their grades for values. The final version of the student_grades dictionary will be checked.
DO NOT modify lines 1-7 to change the existing student_scores dictionary.
This is the scoring criteria:
Scores 91 - 100: Grade = "Outstanding"
Scores 81 - 90: Grade = "Exceeds Expectations"
Scores 71 - 80: Grade = "Acceptable"
Scores 70 or lower: Grade = "Fail"
Expected Output '{'Harry': 'Exceeds Expectations', 'Ron': 'Acceptable', 'Hermione': 'Outstanding', 'Draco': 'Acceptable', 'Neville': 'Fail'}'
Here is my code:

Trying to learn how to think in jq script.
Given this data:
...ANSWER
Answered 2022-Feb-18 at 19:34You have an array of objects called "characters" each containing a "first" and "last" variable. Now to get the first one. Go characters[0].first which would return. "Fred" Or characters.[3].last would return "Weasley" Note the first entry in array is fetched by index 0. Make sense?
QUESTION
I am really stuck with this exercise. How can I with a for loop add the same keys with a new values to a different dictionary in Python?
Goal is to loops through student grades and replace them with "Excellent", "Bad", etc.
This is as far as I could get:
...ANSWER
Answered 2022-Feb-08 at 18:32You can add values to a dictionary by simply assigning the value to the dictionary indexed by the key. For example, student_grades["Harry"] = "Excellent"
You can do the same in your loop:
QUESTION
student scores:
...ANSWER
Answered 2022-Feb-07 at 04:24As the exception message points out, the line student_grades += key
isn't doing anything that makes sense. student_grades
is an (initially empty) dictionary, and key
is a string with the name of a student in it. You can't add those things together. I'm not even sure what you intended it to do, so I can't exactly tell you what to do differently to achieve your objective.
What I do see is that you're modifying the dictionary with the input scores in place in the if
/elif
blocks. Perhaps you don't want to be doing that? If you changed all the assignment statements to use student_grades
instead of student_scores
(while leaving the references to students_scores
in the if
and elif
conditions), you'd probably get what you wanted, without any extra steps:
QUESTION
In a website with lawyers' work details, I'm trying to scrape information through this 4 layered algoritm where I need to do two FormRequests:
- Access the link containing the search box which submits the name of the lawyer requests (image1) ("ali" is passed as the name inquiry)
- Make the search request with the payload through FormRequest, thereby accessing the page with lawyers found (image2)
- Consecutively clicking on the magnifying glass buttons to reach the pages with each lawyers details through FormRequest (image3) (ERROR OCCURS HERE)
- Parsing each lawyer's data points indicated in image3
PROBLEM: My first FormRequest works that I can reach the list of lawyers. Then I encounter two problems:
- Problem1: My for loop only works for the first lawyer found.
- Problem2: Second FormRequest just doesn't work.
My insight: Checking the payload needed for the 2nd FormRequest for each lawyer requested, all the value numbers of as a bulk are added to the payload as well as the index number of the lawyer requested.
Am I really supposed to pass all the values for each request? How can send the correct payload? In my code I attempted to send the particular lawyer's value and index as a payload but it didn't work. What kind of a code should I use to get the details of all lawyers in the list?

QUESTION
I’m developing a VueJs application and added 1000 box model to the scene. Although I’ve set the every geometry’s name attribute when I clicked the box model I couldn’t get the box geometry’s name. I think this is caused by applying merged buffer geometry. Is it possible to get name attribute by clicking in some way ?
Here is my code;
...ANSWER
Answered 2021-Sep-30 at 15:57I assume you're trying to merge the geometry to increase render performance. While you did manage to reduce the number of draw calls the GPU had to make, you also removed all uniqueness of the different BufferGeometry
objects. Your geometry is now represented by one big buffer (debug oGeometriesCubes.attributes.position.array
to see this).
In the interest of performance, we can not only save you GPU draw calls, but also memory, and we can get your box picking to work as well. Let's start from scratch. It will seem like we've taken a step backward, but then it will all fall together...
Your geometry definitionsFirst, you do not need to uniquely identify each BufferGeometry
. Mesh
objects can share geometry! AND materials! This equates to memory savings.
Having unique Mesh
objects also means you can put the name
and translation information at the Mesh
level. Translating at the geometry level 1000 times is expensive, even if you do it up-front like you do. Trust that the GPU can do these translations very quickly from the Mesh level. It's literally the GPU's job.
Now, we're still looking at 1000 meshes, which means 1000 draw calls, right? That's where InstancedMesh
comes into play.
Instancing--in very simple terms--is a way for the GPU to not only re-use the geometry buffer information, but also to perform the drawing of all 1000 meshes in a single swipe, rather than one at a time.
To sum it up:
- Using only one
BufferGeometry
object... - And one material...
- We'll draw 1000 instances...
- In one draw call.
Ready? Let's do it.
