gpgpu - How to use theano within screen session? -

-

i use theano on remote server first ssh (i don't have root on system). works fine, however, if start screen, error when trying import theano.

behavior when not using screen:

>>> import theano using gpu device 0: geforce gtx titan x (cnmem disabled, cudnn 4007)

behavior when using screen:

>>> import theano error (theano.sandbox.cuda): failed compile cuda_ndarray.cu: libcublas.so.7.5: cannot open shared object file: no such file or directory traceback (most recent call last):   file "<stdin>", line 1, in <module>   file "/home/2012/enewel3/.local/lib/python2.7/site-packages/theano/__init__.py", line 103, in <module>     import theano.sandbox.cuda   file "/home/2012/enewel3/.local/lib/python2.7/site-packages/theano/sandbox/cuda/__init__.py", line 697, in <module>     use(device=config.device, force=config.force_device, test_driver=false)   file "/home/2012/enewel3/.local/lib/python2.7/site-packages/theano/sandbox/cuda/__init__.py", line 496, in use     device, cuda_initialization_error_message)) environmenterror: forced use of gpu device gpu, cuda initialization failed error: cuda unavailable

how should use theano within screen session?

the problem due fact that, although screen inherits environment variables, adds, removes, , alters of them. in case, changing value of ld_library_path.

upon entering screen, manually setting environment variable it's proper value fixed problem. me, looks this:

export ld_library_path=/usr/local/cuda/lib64:/usr/local/pkgs/gurobi502/linux64/lib

adding line .bashrc makes sure screens right value. note, adding .bash_profile won't work, because .bash_profile run @ login, while .bashrc run every new shell.
