Torch-TensorRT Version (e. 4 (under Linux and MacOs with both gcc and clang). We suspect this issue is due to some compiler version mismatch (note that we use GCC 5. A possible reason could be that I reinstalled CUDA with a different version and this kind of change affected the environment (context or something). . torch::Tensor even. Then, there is no problem. These are my NVIDIA settings: NVIDIA-SMI 470. 0 for quite some time and decided to update to 1. Unfortunately, the last version of pytorch introduced a problem : the 🐛 Describe the bug When I upgrade to PyTorch 2. I'm not using the version of OpenCV from the Ubuntu repositories. The compilation with python setup. I am running/rebuilding the libraries as mentioned in the Github link and also tried to use the pip Yeah, it doesn’t apply to header only functions. Unfortunately, the last version of pytorch introduced a problem : the I have implemented custom conv2d function in c++ and I want to test it with pytorch model. I use my own cmake routine to compile my extension. I have an undefined symbol error and it seems to me that my cpp file cannot see the function inside the cu Yes, I can confirm I am able to reproduce the same issue as described. After installing torchext, I get the following error when trying to import anything from it OSError: <path>/anaconda3/envs/py311/lib/python3. 14. Now, the problem is slightly different, as it does not detect the "video_reader" package. When I import functorch I get the following error, import functorch I was running an older version of PyTorch ( - built from source) with FuncTorch ( - built from source), and somehow I' undefined symbol: _ZNK3c1010TensorImpl16sym_sizes_customEv #979. pytorch. Anybody for helps and thanks very much. The pytorch dependencies would lead to undefined symbol errors similarly to what you were seeing above with pytorch/libtorch 12. 0 -c pytorch to download from pytorch source, instead of run this: conda install pytorch torchvision cudatoolkit=10. 0. You can add add_definitions(-D_GLIBCXX_USE_CXX11_ABI=0) to your cmake file or configure However, even if I have torchtext also successfully built from source and installed, I couldn’t import it and got the following ERROR: ~ python Python 3. cuda, and CUDA support in general triaged This issue has been looked at a team member, and triaged I also ran into this, but I actually wanted to use GPU, so installing pytorch-cpu was not an option for me. Do you have multiple PyTorch installs? That is often the main issue, in such errors. For what may help, here is the After installing torchext, I get the following error when trying to import anything from it OSError: <path>/anaconda3/envs/py311/lib/python3. After installing pytorch, I might have upgrade my gcc version to 7. 0 -c pytorch.

If not, which OS / compiler do you use? This seems like an ABI issue - you can see the missing symbol contains std::__cxx11::basic_string which means your library is built with the "new" std::string ABI.

More context: the pytorch core library and your extension must be built with the same CXX11 API settings.

So it could be that CUDA_tensor_apply is not that well-liked (with TensorIterator taking the part but not being public API), but I would not know. 0 Hello everybody. Removing it and replacing it with a newer cuBLAS version from CUDA 12 could yield undefined behavior. 🐛 Describe the bug When I upgrade to PyTorch 2. 0 Clang version: Could not collect CMake version: Could not collect Libc version: glibc-2. To my understanding torch is usually built with D_GLIBCXX_USE_CXX11_ABI=0 and the old ABI. You should be able to just define -D_GLIBCXX_USE_CXX11_ABI=0 for your library and you should be fine (in CMake add the line add_definitions(-D_GLIBCXX_USE_CXX11_ABI=0)). 18 release (April 2024) will be the last stable release of the library. Build information about Torch-TensorRT can be found by turning on debug messages. 1. Hello I am trying to use this repo. ?
