I’m trying to install xformers, but am getting an error while building wheels for it. I’m using a Mac.

The full error is:

I had the same issue. After reading this GH comment that it might be problems with versions of different tools, I tried downgrading my GCC and after that, it work successfully :tada:

How:

  1. brew install gcc@7 - install version major 7 version
  2. gcc-7 --version - check the version, it was 7.5 for me
  3. CC=gcc-7 CXX=g++-7 pip install xformer - install xformer using gcc 7.5 version

Any other solutions? I get Error: gcc@7 has been disabled because it is deprecated upstream!

This can be solved by installing llvm:

Just be careful when adding the environment variables since you need to add the correct path to the binaries:

export PATH=“/<PATH_TO_YOUR_LLVM>/llvm/bin:$PATH”
export CC=“/<PATH_TO_YOUR_LLVM>/llvm/bin/clang”
export CXX=“/<PATH_TO_YOUR_LLVM>/llvm/bin/clang++”
