RuntimeError: CUDA out of memory. How setting max_split_size_mb?

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

Laravel Error: Method Illuminate\View\View::__toString() must not throw an exception

There is a very simple solution: don’t cast View object to a string. Don’t: echo View::make(‘..’); or echo view(‘..’); Do: echo View::make(‘..’)->render(); or echo view(‘..’)->render(); For PHP version <7.4 By casting view, it uses __toString() method automatically, which cannot throw an exception. If you call render() manually, exceptions are handled normally. This is the case … Read more

Illegal remote method in java

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

Parameters of a model after .cuda() will be different objects with those before the call. In general, you should make sure that optimized parameters … Read more
