Problem I pretrain DeGCN on NTU RGB+D 60 (cross-subject, 83.3% top-1) then fine-tune on UCF101. Fine-tuning reaches only 58.76%, while training from scratch on UCF101 reaches ~80%. I expected at least comparable performance. Setup Data pipeline. Both datasets are converted to a shared Common15 15-joint space before entering the model: NTU RGB+D 25 joints → Common15 (pelvis/shoulder_center averaged, head/hands/feet dropped) COCO17 keypoints (YOLO + MotionBERT 3D lift) → Common15 (same averaging, face dropped) Both pipelines produce index-identical joint layouts (joint 0 = pelvis in both). NTU25 → Common15: [Image] COCO17 → Common15: [Image] Common15 joint layout (DeGCN input): [Image] Model. DeGCN input shape: (N, C=3, T=64, V=15, M=2)

About running 2 commands at once, for example to run 2 console programs with 1 single command, in PowerShell, one way to do this is with a command in the next format, just by adding ; between each of the 2 commands/sub-commands, all in 1 single line: python C:/path/to/program_2/program_2.py; C:/path/to/program_1/program_1.exe Or if the 2 programs are in the same path, and already being in that path: python program_2.py; ./program_1.exe In this way, the 2 programs run sequentially, one after the other, all in the same terminal window/tab. Now I'm looking for a way to run 2 commands in the next way: At once (1 single action). At the same time (or as close as possible). In parallel. 1 single action that automatically opens a terminal pane for each command, side-by-side, in the same terminal window.

Trying to educate myself from a sample Android app in Android Studio, I have found an ArrayList<String>. In the debugging mode, the value(s) of this array is as below (using the view tool of the IDE) I don't really understand how to recognixe each elenet of the array. I would appreciate any help. The list is constructed as below (from a json file) public static List<ArrayList<String>> getPrintDataFromJson(Context context, String jsonFileName, int copies, float multiple) { try { String jsonContent = AssetJsonReader.readJsonFromAssets(context, jsonFileName, error -> Log.e(TAG, "Json not found: " + jsonFileName + ", error: " + error)); if (jsonContent == null || jsonContent.isEmpty()) { Log.e(TAG, "JSON is empty: " + jsonFileName); return null; } retur

I am trying to make a CSS selector to match elements with a class that starts with ai-. So for example, I would want to match items with ai-images or ai-videos, but not kizuna-ai-images or samurai-images. <div class="category ai-images"/> <!-- Match --> <div class="category ai-videos"/> <!-- Match --> <div class="category kizuna-ai-images"/> <!-- Don't match --> <div class="category samurai-images"/> <!-- Don't match --> I tried: Matching the start of the attribute value with [class^="ai-"] will only match if the first class starts with ai-. Using a wildcard in the class name via .ai-* is considered invalid CSS. Matching any class containing ai- with [class*="ai-"]

I'm trying to display a PDF file inline in the browser using Laravel, but instead of showing the file, the browser downloads it. Here is my code: return Storage::disk('public')->response( $path, $responseFileName, ['Content-Type' => 'application/pdf'], 'inline' ); This route is accessed via a GET request. My expectation is that the PDF should open in the browser (inline), but instead it always triggers a download. What am I missing? Is there something wrong with how I'm setting the headers or using the `response()` method? Any help would be appreciated.

I'm using celery with django to run some task that runs multiple threads querying the database. The example below is a simplified version of the original one in a larger project, but the logic and results are the same. The error occurs either way. models.py from django.db import models class Example(models.Model): name = models.CharField(max_length=255) urls.py from django.urls import path from core.views import ExampleView urlpatterns = [path('example/', ExampleView.as_view())] views.py from core.tasks import run_task from rest_framework.response import Response from rest_framework.views import APIView class ExampleView(APIView): def get(self, request, *args, **kwargs): run_task.delay() return Response(status=200) tasks.py from concurrent.futures import ThreadPoolExecutor, as_completed

I'm processing a large pandas DataFrame (500k rows) where each row requires an HTTP request. I switched from requests to aiohttp + asyncio expecting a significant speedup, but the async version runs just as slowly as the synchronous loop. I can't figure out where the concurrency is being blocked. Here's a minimal reproducible example: import asyncio import aiohttp import pandas as pd import time # Sample DataFrame with 100 rows, each hitting a delayed endpoint df = pd.DataFrame({ 'id': range(100), 'url': ['http://httpbin.org/delay/0.1'] * 100 }) async def fetch(session, url, row_id): async with session.get(url) as response: await response.text() return row_id async def process_dataframe(df): async with aiohttp.ClientSession() as session: tasks = [] for _, row in df.iterrows(): task = asyncio.create_task(fetch(session, row['u

How to force ComboBox1_SelectedValueChanged to reset ComboBox to its starting appearence, showing only the user prompt label.
