libdlprim.so
or libdlprim_core.so
. the libpt_ocl.so
is linked with them. Just make sure LD_LIBRARY_PATH
points to a location that contains these libraries. libpt_ocl.so
will load them automatically.dlprim_core
the libpt_ocl.so
was compiled with and the actual loaded are different, maybe you built but not installed?Thanks for your quick response.
- You don't need to load
libdlprim.so
orlibdlprim_core.so
. thelibpt_ocl.so
is linked with them. Just make sureLD_LIBRARY_PATH
points to a location that contains these libraries.libpt_ocl.so
will load them automatically.
I see. I just want to check if I load the wrong libraries.
- It seems that the version of
dlprim_core
thelibpt_ocl.so
was compiled with and the actual loaded are different, maybe you built but not installed?
I tried again to reinstall pytorch_dlprim with the correct libraries but still get the same error.
This is the cmake script I used to compile pytorch_dlprim:
cmake .. -DCMAKE_PREFIX_PATH=/home/guol678/newlibs/miniconda/envs/dlprim/lib/python3.10/site-packages/torch/share/cmake/Torch/ -DDLPRIM_INC=/home/guol678/newlibs/dlprim/include/ -DDLPRIM_LIB=/home/guol678/newlibs/dlprim/lib/ -DCMAKE_C_COMPILER=/home/guol678/newlibs/gcc-9.4/bin/gcc -DCMAKE_CXX_COMPILER=/home/guol678/newlibs/gcc-9.4/bin/g++ -DCMAKE_INCLUDE_PATH=/home/guol678/newlibs/pocl/include/ -DCMAKE_LIBRARY_PATH=/home/guol678/newlibs/pocl/lib/
And I tried torch.ops.load_library again,
>>> torch.ops.load_library("/home/guol678/newlibs/miniconda/envs/dlprim/lib/libsqlite3.so")
>>> torch.ops.load_library("/home/guol678/newlibs/dlprim/lib/libdlprim_core.so")
>>> torch.ops.load_library("/home/guol678/newlibs/miniconda/envs/dlprim/lib/libsqlite3.so")

There are some issues related to build ABI. I moved to pytorch nightly that gives way better out of tree support.
Look at this branch true_out_of_tree_support
- it is still experimental and some nets fail but the build process is much simpler
Hi Beilis,
I have done the installation following your instructions. I am seeing an error while loading libdlprim_core.so with torch.ops.load_library. I didn't have issues with loading libdlprim.so and libdlprim_core.so. Could you please give me some hints? Thank you!
