Stucked at Compiling surel_gacc on Macbook M1 chip

[fs302]

Hi there, when trying to run this repo at MacBook Pro (13-inch, M1, 2020), I found some obstacles:

1. failed at recover conda environment using conda env create -f environment.yml
   
2. failed at compiling surel_gacc
   
   Hope to get help with these issues. Can we run SUREL without c acceleration?

Hello, thank you for your interest in our work. Note that SUREL has not been tested on MacOS.

1. environment.yml is exported from Ubuntu 20.04, some packages may not work on Mac.
2. SUREL depends on C extensions. From the error trace, it looks like your environment doesn't have openmp properly configured.

Hi,

Sorry for inserting myself into the conversation 😅

I saw the issue and had remembered facing the same problem on my M1 as well. The fix that worked for me:
You need to update the clang compiler to one that comes with Homebrew.
Prerequisite: Make sure homebrew is installed (https://docs.brew.sh/Installation) on your macbook.
Steps after making sure homebrew is installed:

1. Install llvm on your homebrew: brew install llvm
2. Point to the brew clang compiler (could be different version for you): export CC=/opt/homebrew/Cellar/llvm/13.0.1_1/bin/clang

This should ideally work. Please double-check if you have the clang compiler in this path export CC=/opt/homebrew/Cellar/llvm/13.0.1_1/bin/clang. It could be a different version for you.

@venomouscyanide many thanks! It works.

But another Error raised after run the script python main.py --dataset ogbl-collab --metric hit --num_step 4 --num_walk 200 --use_val
