These are the errors I get trying to pip or manually install torch-spline-conv and torch-scatter.

I'm on a Mac OSX 10.12.6

Hi,

I‘m not sure if I can help you, as this seems to be a problem with Mac and the new Extension API. Please verify that the official extension-cpp examples work on your machine and report back.

Hi,
I could not compile the extension-cpp/cpp folder via python jit.py
There's an issue with my system defaulting to the old clang complier which uses C++ 4.2.1.. I tried installing gcc8 with homebrew and linked it, but checking c++ -v still points to clang.

[rusty1s]

You need to use clang on macOS, and personally, this works fine for me :(

After reinstalling anaconda and installing a new environment, I was able to pip install torch-scatter just fine. But now I have trouble importing it.

Please try installing from source:
python setup.py install

I get the same error message on Linux "Symbol not found: __ZN2at5ErrorC1ENS_14SourceLocationESs".
After installing from source the error is still the same.

[cysmnl]

I am using Homebrew GCC 8.2.0 with an anaconda environment (python 3.7, GCC 4.0.1)
Tried installing pytorch_scatter-1.0.4 from source, no luck. I get the same error.
I can compile pytorch/extension-cpp/cpp, but still get error "Symbol not found: __ZN2at5ErrorC1ENS_14SourceLocationESs" when I import lltm_cpp.

Everything installs fine in redhat Linux in an anaconda environment (python 3.7, GCC 7.2.0)

[rusty1s]

I could reproduce the error on a mac. I will look into it.

[fighting41love]

Same error.

After installing from source, the error still exists
undefined symbol: _ZN2at6detail20DynamicCUDAInterface10set_deviceE

[rusty1s]

I could resolve this issue by setting up a clean miniconda environment. It seems to be fixable by clearing the pip cache (rusty1s/pytorch_scatter#7).

FYI,
weirdly enough I could only make torch-scatter install in my conda environment after having it installed in my root python3 via pip3.
So clearing the wheels in the root pip cache was actually the wrong thing to do in my case (then again, it's in my specific case).
I'm not familiar with the inner workings of pip/conda to give recommendations, just wanted to add it to the thread. =)

PS: Thank you very much for the awesome library!

Installing clang compiler tools within my conda environment worked for me:

conda install -y clang_osx-64 clangxx_osx-64 gfortran_osx-64
