Have any of you tried Expected; in practice? It’s quite natural, I used it even before I saw this talk. How would you apply this idiom to functions returning nothing (that is, void functions)? The form presented in the slides has some subtle implications: The exception is bound to the value. It’s ok to handle … Read more
The error: ‘int’ object has no attribute ‘__getitem__’ means that you’re attempting to apply the index operator [] on an int, not a list. So is col not a list, even when it should be? Let’s start from that. Look here: col = [[0 for col in range(5)] for row in range(6)] Use a different … Read more

Swift 5 If you need a loop with dynamic value-range, I suggest that using stride(to:by:) instead of ..< or … Basically ..< or … will be crashed if start_index > end_index. This will be crash: let k = 5 for i in 10…k { print(“i=\(i)”) } for i in 10..<k { print(“i=\(i)”) } How to … Read more
APIs with functions like getUserMedia, getDisplayMedia and enumerateDevices require a secure context, access to these from http: origins has been removed in Chrome back in 2019 For development, the easiest solution may be to create a self-signed certificate. –UPDATE– For development the easiest solution is to run from localhost, as that’s considered secure – see … Read more
The max_split_size_mb configuration value can be set as an environment variable. The exact syntax is documented at https://pytorch.org/docs/stable/notes/cuda.html#memory-management, but in short: The behavior of caching allocator can be controlled via environment variable PYTORCH_CUDA_ALLOC_CONF. The format is PYTORCH_CUDA_ALLOC_CONF=<option>:<value>,<option2>:<value2>… Available options: max_split_size_mb prevents the allocator from splitting blocks larger than this size (in MB). This can help … Read more
All of the methods on a RMI Remote interface must declare RemoteException in their throws clause, e.g.: public String getId() throws RemoteException; It’s not clear why the exception names getId() specifically, it’s probably just the first method it checked. Also, the getLeafNodes() and getNeighborhoodList() methods should have return types that specify Node, not NodeImpl, otherwise … Read more
