Running Demo File Shared Libraries issue

[TamourBilal6]

I am facing this shared libraries error when i am trying to start demo.py

If you depend on functionality not listed there, please file an issue.

Traceback (most recent call last):

From where do you run the python script? Because tf_nndistance_so.so is loaded from a relative path. You should run the script directly from the project's root.

If this isn't the problem, then do these files exist? If not, you should look at your cuda version (you can see it using nvidia-smi inside the terminal). If you use cuda9.0 you can copy the files from the archive-cuda-9 folder, if you run 10.0, then copy from the 10.0 folder.

If you run any other version, you'll need to compile the cuda files using the procedure described inside the Makefile file in the external folder.

If this still doesn't work, you can reply to this thread I'll try to help you out.

I have made changes in the makefile and given path to the CUDA and Nvidia files but still facing the same issue

Hi @topinfrassi01 I have sort out the issue by copying files from tf_nndistance_so.so from CUDA 9 archieve to external folder however at the very next i found out "libcudart.so.9.0: cannot open shared object file: No such file or directory" this issue. Can u plz help me out to resolve this issue. Regards

If libcudart 9.0 can't be found, I believe it is because you are not using CUDA 9.0. Could you maybe give me the given path for CUDA (that you put inside the Makefile) and the output of the nvidia-smi command?
