To my understanding, the built-in PyTorch operations all automatically handle batches through implicit vectorization, allowing parallelism across multiple GPUs. However, when writing a custom opera...

If we << a torch::Tensor #include <torch/script.h> int main() { torch::Tensor input_torch = torch::zeros({2, 3, 4}); std::cout << input_torch << std::endl; return 0; } w...

I asked a similar question about linking a project with OpenCV a few days ago. I got that working, but now I've hit a very weird problem using CMake and adding LibTorch to the project. If I only u...

i downloaded libtorch and make these files on macbook pro ARM: example-app/ build/ libtorch/ CMakeLists.txt example-app.cpp then i used these commands for build torch: cmake -DCMAKE_PREFIX_PAT...

I have the following configuration in the .pro file TEMPLATE = app CONFIG += console c++11 CONFIG -= app_bundle CONFIG -= qt CONFIG += thread SOURCES += main.cpp INCLUDEPATH += /usr/local/includ...

When testing a network in PyTorch one can use with torch.no_grad():. What is the Libtorch (C++) equivalent? Thanks!

I am trying to run inference on a jit traced model in C++ and currently the output I get in Python is different than the output I get in C++. Initially I thought this be caused by the jit model its...

I'm currently using the has_storage() method to check whether a tensor is empty or not, but I wonder if there is anything better other than this! and whether there are any implications involved in ...

I'm using the same traced model in pytorch and libtorch but I'm getting different outputs. Python Code: import cv2 import numpy as np import torch import torchvision from torchvision import transf...

I have a std::vector<std::vector<double>> where I want to conver it into a torch::Tensor in libtorch. However it seems, the torch::tensor(), or torch::from_blob(), can't be used for thi...

Using the C++ libtorch frontend for Pytorch I want to create a torch::Tensor from a C++ double[] array. Comming from a legacy C/C++ API. I could not find a simple documentation about the subject no...

In the official PyTorch C++ examples on GitHub Here you can witness a strange definition of a class: class CustomDataset : public torch::data::datasets::Dataset<CustomDataset> {...} My und...

I'm trying to build a program using cmake. For several reasons, the program must be built using static libraries rather than dynamic libraries, and I need to use PyTorch so this is what I've done: ...

In Python given a 2-D tensor, we can use tensor[:,:2] to slice the a 2x2 matrix of the first two elements in the top left of the matrix, e.g. : x = torch.tensor([[-1.4673, 0.9980, -2.1427, -1.1798...

I am using torch C++ frontend and want to have a tensor with specified value in it. To achieve this one may allocate memory and set value by hand, then use torch::from_blob to build a tensor on the...

I have around 26 static libraries such as liba.a, libb.a, libc.a, ..., libz.a. There are two catches here: 1) circular dependencies between for example liba.a and libb.a; 2) some lib*.a has stati...

In the C++ version of Libtorch, I found that I can get the value of a float tensor by *tensor_name[0].data<float>(), in which instead of 0 I can use any other valid index. But, when I have de...
