Build fails: cannot import name 'generate_file' from 'py_gen'

Hi,

Followed the instructions from Readme to build portblas for Intel DPCPP compiler and here are my exact steps:

export CC=/opt/intel/oneapi/2024.0/bin/compiler/clang
export CXX=/opt/intel/oneapi/2024.0/bin/compiler/clang++
mkdir build
cd build
cmake -GNinja ../ -DSYCL_COMPILER=dpcpp
ninja

This throws the following errors:

Happy to help to fix this.
