The Exception I get when using the istream / ostream versions is: istream reader failed: reading file.Įxception raised from validate at. Deserialize the ScriptModule from file as saved in Python (this works flawlessly). TorchScriptFileFromPython = "C:/Test/MyModule.pte"

Then, for testing purposes, I import it again using the above denoted module = torch::jit::load(istream_in).

Then, for testing purposes, I export it again using the above denoted torch::jit::ExportModule(module, ostream_out).

Then, I load this TorchScript model successfully in C++ using torch::jit::load(file_path) (so not using the std::istream overload.).

In Python I have developed and trained a model.

To test, I developed a small test script. Load(std::istream& in, c10::optional device = c10::nullopt) / The istream must contain a serialized `Module`, exported via (from …\include\torch\csrc\jit\serialization\import.h) /// Loads a serialized `Module` from the given `istream`. (from …\include\torch\csrc\jit\serialization\export.h) TORCH_API void ExportModule(Ĭonst ExtraFilesMap& metadata = ExtraFilesMap(), Below I give some details:įor clearity, I try to use the following 2 functions: I want to Export my Torch Module and write it using a std::ostream, then I want to read my exported Torch Module using a std::istream. Is this a bug in LibTorch, or am I doing something wrong? I have no clue where to start debugging this, I hope somebody can help me or give me some input so I can continue my search for a solution. I develop a program in C++ which uses a PyTorch model. But suddenly, it fails to compile, because apparently, when supplied a custom deleter, the unique_ptr becomes a different type.I have a problem which I cannot solve. So I have to supply a custom deleter (that does nothing) for the cin case.

This works for ifstream but not for cin, because you can't delete cin. At first, I tried unique_ptr open_for_read(const string& filename) So I figure, the modern C++ way would be to use smart pointers with streams. It works, and it's safe to fclose(stdin) later on (in case one doesn't forget to), but then I would lose access to the stream methods such as std::getline. I first considered the old-school FILE*: FILE *open_for_read(const char *filename) Otherwise, create and open a file, check for error, and return it.Īnd here comes my question: what is the best practice to design/implement such a function? What should it look like?.If the filename is -, return standard input/output.I need a helper function (or two) that does the following: I'm writing a command-line utility for some text processing.
