RuntimeError: Error in dlopen

[abastola0]

I faced this issue while running pytorch application but some similar issues were mentioned for julia as well (referenced here: #JuliaLang/julia#49246)

RuntimeError: Error in dlopen: libtorch_cuda_linalg.so: cannot open shared object file: No such file or directory

Here is the debug output:

     36333:	file=libtorch_cuda_linalg.so [0];  dynamically loaded by /lib/libdlfaker.so [0]

The first hit was correct (trying file=home/abastol/modules/anaconda3/envs/newsn/bin/../lib/libtorch_cuda_linalg.so) but the not sure about the second one. There were two windows opened so not sure if the second hit (trying file=/usr/lib/libtorch_cuda_linalg.so)was for that (some concurrency issue perhaps).

Anyway a manual export to the conda env library path seems to fix this issue (referenced here:#JuliaLang/julia#49246) but this might be temporary.

I believe this is a duplicate of #107. If so, it is a known issue, and the workaround is documented in the VirtualGL User's Guide. (The workaround is just a convenience option to vglrun that does exactly what you describe: adding the application's library directory to LD_LIBRARY_PATH. Refer to #107 and the VirtualGL User's Guide for an explanation of why that is necessary.)
