ImportError: libze_loader.so.1: cannot open shared object file: No such file or directory

Describe the issue

I am running on WSL and Ubuntu 22.04

Even after installing the oneAPI base toolkit, and doing the

source /opt/intel/oneapi/compiler/latest/env/vars.sh
source /opt/intel/oneapi/mkl/latest/env/vars.sh
export LD_LIBRARY_PATH=/opt/intel/oneapi/mkl/latest/lib:$LD_LIBRARY_PATH
source /opt/intel/oneapi/setvars.sh
export SYCL_CACHE_PERSISTENT=1
export BIGDL_LLM_XMX_DISABLED=1

I am still getting this import error. Would appreciate your help.

Hi @bconsolvo , Ubuntu 20.04 has been out of IPEX support scope for a while. Would you try with 22.04? thanks.
I assume that this had been fixed at level-zero but for Ubuntu 22.04 only.

Nevermind, I was using Ubuntu 22.04 anyway. Disregard my initial comment of 20.04. Still same error. Thanks.

Have you already installed the level-zero GPU driver in WSL2? If not:

wget -qO - https://repositories.intel.com/gpu/intel-graphics.key | \
  sudo gpg --yes --dearmor --output /usr/share/keyrings/intel-graphics.gpg
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/intel-graphics.gpg] https://repositories.intel.com/gpu/ubuntu jammy/lts/2350 unified" | \
    sudo tee /etc/apt/sources.list.d/intel-gpu-jammy.list
sudo apt update
sudo apt install level-zero intel-level-zero-gpu

That will install the libze_loader.so (from level-zero) and the runtime for the Intel GPU.
