RuntimeError: Could not load any ArrayFire libraries

[luckydog1996]

I have include export LD_LIBRARY_PATH=/home/ztzhao/Downloads/arrayfire/lib64:$LD_LIBRARY_PATH in my ~/.bashrc, but when I want to run python -m arrayfire.tests it still can not load arrayfire libraries.

Are you using the cuda backend? If so you may also need to add the cuda paths. For example:
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:/usr/local/cuda/nvvm/lib64/:/opt/arrayfire/lib64/:$LD_LIBRARY_PATH
More details here: https://github.com/arrayfire/arrayfire-python/wiki
If that doesn't help, can you show the specific error message you are seeing? This may be better suited for the arrayfire-org slack channel...

After change I run python -m arrayfire.tests, it gives different error:
(base) ztzhao@cw1:~$ python -m arrayfire.tests

I believe this can be combined with Issue #248 , since the error messages are the same.

[WKrauze]

The solution to this problem is given in #248 . I believe this issue can be closed.
