Open mlv42 opened 2 months ago

mlv42 commented 2 months ago

I get the error :

OSError: dlopen(/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/torch_scatter/_version_cpu.so, 0x0006): Symbol not found: __ZN3c1017RegisterOperatorsD1Ev Referenced from: <85F5D618-9A81-323E-B8CF-4EA588421020> /Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/torch_scatter/_version_cpu.so Expected in: /Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/torch/lib/libtorch_cpu.dylib

when I import torch_scatter. I have:

and I have installed torch_scatter using this line of code:

pip install torch-scatter -f https://data.pyg.org/whl/torch-2.2.2+cpu.html

on a Mac.

How can I fix it? I am sorry but I am not familiar with how these kind of issues work.

rusty1s commented 2 months ago

How did you install PyTorch? Are you using the conda-forge package?

mlv42 commented 2 months ago

I used pip install torch and no, I am not using conda-forge . Should I?

rusty1s commented 2 months ago

No, that sounds good then. Is this ARM or Intel mac?

mlv42 commented 2 months ago

It's an Intel Mac

rusty1s commented 2 months ago

Got it. What happens if you simply install via

pip uninstall torch-scatter
pip install torch-scatter
mlv42 commented 2 months ago

I get the error:

note: This error originates from a subprocess, and is likely not a problem with pip. ERROR: Failed building wheel for torch-scatter Running setup.py clean for torch-scatter Failed to build torch-scatter ERROR: Could not build wheels for torch-scatter, which is required to install pyproject.toml-based projects Note: you may need to restart the kernel to use updated packages.

when I run pip install torch-scatter after I run pip uninstall torch-scatter.

Sorry for late reply:

Can you run with

pip install --verbose torch-scatter

This should give a more descriptive error message.

I had this same issue however I am using python 3.10, also on an Intel Mac. Im using macOS 14.14.1 and was getting a MacOSX SDK error:

python3.10/site-packages/torch/include/ATen/core/function_schema.h:596:50: error: 'value' is unavailable: introduced in macOS 10.13

I set the macOS deployment target to 10.14 (something that isn't too recent but greater than 10.13 should work). Then installed successfully.

export MACOSX_DEPLOYMENT_TARGET=10.14
pip install --no-cache-dir torch-scatter -f https://data.pyg.org/whl/torch-2.2.1+cpu.html

I think this is because some C++17 dependencies used in this package are not supported with earlier macOS versions.

check https://github.com/rusty1s/pytorch_scatter/issues/448 try : pip install torch-scatter -f https://data.pyg.org/whl/torch-2.2.1+cpu.html

i believe you are installing the wrong version of torch-scatter.
