You can basically install (or unpack) the vanilla wheel for macOS ARM64 and take the

By the way, if you are interested in the relative performance of https://twitter.com/danieldekok/status/1453070009266315267 For an M1 compared to a Ryzen 5700X, see the slide Dutch model performance in: https://danieldk.eu/Research/Presentations/clin2021.pdf These benchmarks are using a multi-task transformer model, implemented using If you are curious about MPS compared to PyTorch without MPS (which uses the AMX matrix multiplication co-processor), I am currently working on support for PyTorch with MPS in spaCy. So far the number are:
See: https://twitter.com/danieldekok/status/1529057447700226048 This should also be roughly the ballpark, since the AMX co-processor in the M1 Pro/Max is ~2.4 TFLOPS single-precision, whereas the GPU in the Pro and Max are respectively ~5 TFLOPS and ~10 TFLOPS. |

No, only from AMX through Accelerate. For MPS you need to use an |

thanks. almost a 2 part problem to be honest.
thanks! |

I run into namespacing issue with pytorch, seems like this is a new thing. Any idea on how to solve this? perhaps it'd be great if you can share the lib/ include/ so that I can compile against that?

@sunilmallya are you still running into that error? I'm experiencing the same error. |

Hi, same issue for me as well. Tried all libtorch zips (both linux and mac) and nothing works. I have a dockerfile for replicating this as well, so please let me know how can I help. |

Compilation is successful but when running getting below error: |

Siliicon M2 mac here, I have separate condas setup for arm64 and x86_64 as rosetta. But am getting the same linker errors trying to compile in either environment. Same errors with earlier torch-sys version. On the other hand pytorch is working great for python with mps support in arm64. Happy to test or help if possible. Posting arm64 errors first then x86_64 errors. arm64 errors: warning: clang: warning: -Wl,-rpath=/Users/lc/rust_projects/cr/libtorch/lib/lib: 'linker' input unused [-Wunused-command-line-argument] error: failed to run custom build command for Caused by: --- stderr error occurred: Command "c++" "-O0" "-ffunction-sections" "-fdata-sections" "-fPIC" "-gdwarf-2" "-fno-omit-frame-pointer" "-arch" "arm64" "-I" "/Users/lc/rust_projects/cr/torch-sys/include/include" "-I" "/Users/lc/rust_projects/cr/torch-sys/include/include/torch/csrc/api/include" "-Wl,-rpath=/Users/lc/rust_projects/cr/libtorch/lib/lib" "-std=c++14" "-D_GLIBCXX_USE_CXX11_ABI=1" "-o" "/Users/lc/cr/tch-m1/target/debug/build/torch-sys-689ca3535ca01ed0/out/libtch/torch_api.o" "-c" "libtch/torch_api.cpp" with args "c++" did not execute successfully (status code exit status: 1). x86_64 errors: warning: clang: warning: -Wl,-rpath=/Users/lc/rust_projects/cr/libtorch/lib/lib: 'linker' input unused [-Wunused-command-line-argument] error: failed to run custom build command for Caused by: --- stderr error occurred: Command "c++" "-O0" "-ffunction-sections" "-fdata-sections" "-fPIC" "-gdwarf-2" "-fno-omit-frame-pointer" "-m64" "-arch" "x86_64" "-I" "/Users/lc/rust_projects/cr/torch-sys/include/include" "-I" "/Users/lc/rust_projects/cr/torch-sys/include/include/torch/csrc/api/include" "-Wl,-rpath=/Users/lc/rust_projects/cr/libtorch/lib/lib" "-std=c++14" "-D_GLIBCXX_USE_CXX11_ABI=1" "-o" "/Users/lc/cr/tch-m1/target/debug/build/torch-sys-bffbc597d35ab5cb/out/libtch/torch_api.o" "-c" "libtch/torch_api.cpp" with args "c++" did not execute successfully (status code exit status: 1). warning: build failed, waiting for other jobs to finish... |

That was true! It was looking in lib/lib |

It built in x86_64 conda environment on silicon M2 mac!! - the Rust version had to be from the conda environment and there was a path problem initially linking back to arm rustc version. The LIBTORCH_INCLUDE now points to the include directory but the LIBTORCH_LIB points just to the LIBTORCH dir. The permissions were wrong on the downloaded libtorch. There were no permissions to x, only rw. So needed to change permissions or run in sudo. |

Totally new to Rust here, so please bear with me if my words don't make sense. After trying for 1 hour, I finally got

Not sure if anyone else is still having issues or if this was already solved elsewhere, but I managed to get a working build on Apple M1 Pro 16GB 14.1.1 using libtorch built from source. TLDR;This how to use libtorch nightly, built from source on M1 Pro with MPS. Resulting tch changes Here's the rough outline of the steps: Build libtorchFollow these steps to build libtorch from source What I ran: git clone -b main --recurse-submodule https://github.com/pytorch/pytorch.git

I still get a build error for a Tauri app that I am running, the log is as follows Currently I have libtorch v2.2.1 unzipped in a local directory and I have LIBTORCH pointing to it. I have tried @ShaojieJiang's approach as to no avail. I get this same error when I try to follow rust-bert's installation mechanism The error at the start suggested that I didn't have C++17 on my machine but I do. I can compile a simple C++ program if I set the |

According to your logs, you're using tch-rs 0.13.0, this version is I think for libtorch 2.0.0. Version 0.15.0 should be used for libtorch 2.2.0 (and might work with 2.2.1). |

This resolved it thanks. 💯 |
I'm doing some development on an M1 Mac. And, I'm having some trouble installing
LibTorch.Though I assumed it wouldn't work, I tried just installing from the link that usually provides an x86_64 build. Of course, it didn't:
I've also tried installing follow the guide for the Metal Accelerated version. I also didn't expect this to work, and it did not.
I also don't see an obvious solution here.
So, what do I need to do? I'd be happy to provide additional docs if there's a solution.
