I’m training a LightGBM model where the evaluation metric is Spearman correlation (rank-based). To better align training with the metric, I transform the continuous target y into ranks scaled to [0,1]: y_rank = pd.Series(y).rank(method="average") y_rank = (y_rank - 1) / (len(y_rank) - 1) I then train LGBMRegressor on y_rank (features are all numeric, no categorical). Dataset is ~7,500 rows and ~18 numeric features. However, during training I often see: \[LightGBM\] \[Warning\] No further splits with positive gain, best gain: -inf and the model ends up producing nearly constant predictions (almost no variance), which makes the Spearman score poor. Questions: What are the most common causes of best gain: -inf / “no positive gain” in this setup (rank targ

I'm trying to import mapdb 3.1.0 which has an open version range for Guava: <guava.version>[15.0,)</guava.version> ... <dependency> <groupId>com.google.guava</groupId> <artifactId>guava</artifactId> <version>${guava.version}</version> </dependency> I know it is generally discouraged to use version ranges, but no more than that. What I would expect happen in this case: Maven will download maven-metadata.xml for this artifact, sort versions using version sorting rules, pick the last one (observing bounds). Then download and use it. It is not what happens (Maven 3.9): Instead, it seems to download every version in the range, 200 of these, POM and parent-POM. In the middle of the list there is a problematic version for whose parent-POM does not exist, which causes the whole build to fail without

I’m implementing an Instagram Auto-DM system using Meta Graph API and hit a serious App Review deadlock. What works ✅ In Live Mode: Webhooks fire correctly Payload reaches server BUT sending messages fails with: (#3) Application does not have the capability to make this API call What doesn’t work ❌ In Development Mode: Admin + IG Tester account IG Professional account Page subscribed to app Webhook verified /subscribed_apps confirms subscription ➡️ Webhook never fires Why this is a problem Meta App Review requires a video showing: Trigger Webhook reception Message send Message delivered in Instagram app But: Live Mode → webhook works, API blocked Dev Mode → API allowed, webhook dead Questions Is this expected Meta behavior? Are Instagram webhooks disabled in Dev mode? How are devs

I have an emscripten project which relies on the -sASYNCIFY features. Trying to compile it with fsanitize=address as additional argument to reveal problems fails because the functions wrapped with the EM_ASYNC_JS macro are then not seen by the compiler anymore. I have a function EM_ASYNC_JS(void,addPersistentDirsInt,(),{ and the compiler raises error: undefined symbol: addPersistentDirsInt (referenced by root reference (e.g. compiled C/C++ code)) warning: To disable errors for undefined symbols use `-sERROR_ON_UNDEFINED_SYMBOLS=0` warning: _addPersistentDirsInt may need to be added to EXPORTED_FUNCTIONS if it arrives from a system library Error: Aborting compilation due to previous errors at finalCombiner (file:///Users/leo/w/github/emsdk/upstream/emscripten/src/jsifier.mjs:889:13) at Module.runJSify (file:///Users/leo/w/github/emsdk/upstream/emscripten/src/jsifier.mjs:925:5)

Description I have recently updated my code to put layouts in resources/views/layouts instead of resources/views/components/layouts. This means I have also updated all pages that use these components to use Blade's layout namespace. Example Rendering a layout in resources/views/layouts/app/sidebar.blade.php used to be done by... <x-layouts.app.sidebar> ... </x-layouts.app.sidebar> Now after the migration... <x-layouts::app.sidebar> ... </x-layouts::app.sidebar> The Problem I have a View composer setup for my sidebar to populate the sidebar with data. Before the migration the composer was called in AppServiceProvider like so... Facades\View::composer('components.layouts.app.sideba

I have a VBA project to assist Sage users by making upload files. As part of this the finished workbook is saved to a temp folder. Once the onward work is completed. I want to delete the file and the folder. I can delete the file, but deleting the folder is locked as in use (by Excel and my workbook containing my project) I proved this by closing Excel, then re-opening and the deletion works fine. However, in use by the end user restarting Excel is not acceptable. I've tried two methods, both without success. How do I unlock the folder? Sub DirDel() 'Method 1 Dim MyPath As String 'Checks if Dir exists deletes it. MyPath = "C:\Sage Test" If Not (Len(Dir(MyPath, vbDirectory)) = 0) Then MsgBox Len(Dir(MyPath, vbDirectory)) & "dir" 'Kill MyPath &"\*.*" Currently disabled as no file present. RmDir MyPath MsgBox "Deleted" Else MsgB
