dpctl installed into virtual env fails to import #1892
Description
I executed the following steps;
conda create -n py312 -c conda-forge --override-channels python=3.12 virtualenv
conda activate py312
python -m venv pypi_venv
source pypi_venv/bin/activate
pip install --no-cache-dir --index-url https://software.repos.intel.com/python/pypi dpctl==0.18.1
python -c "import dpctl"Observed output:
(pypi_venv) (py312) opavlyk@opavlyk-mobl:~/tmp$ python -c "import dpctl"
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/home/opavlyk/tmp/pypi_venv/lib/python3.12/site-packages/dpctl/__init__.py", line 29, in <module>
from ._device_selection import select_device_with_aspects
File "/home/opavlyk/tmp/pypi_venv/lib/python3.12/site-packages/dpctl/_device_selection.py", line 20, in <module>
from ._sycl_device import SyclDevice, SyclDeviceCreationError
ImportError: libintlc.so.5: cannot open shared object file: No such file or directory
Executing patchelf --set-rpath '$ORIGIN:$ORIGIN/../../../' --force-rpath $VIRTUAL_ENV/lib/python3.12/site-packages/dpctl/*.cpython*.so fixes the problem, because it allows Python modules to find the dependent DPC++ runtime libraries in Python prefix's lib folder.
