error while loading shared libraries: libnvidia-ml.so.1: cannot open (...)

[Roccosi7]

Hi!
Ive got a problem with Hashcat on Ubuntu.
When I try to run
sudo ./cudaHashcat-plus32.bin -m 2500 pam.hccap dic_sortiert.txt
I get the following error:
./cudaHashcat-plus32.bin: error while loading shared libraries: libnvidia-ml.so.1: cannot open shared object file: No such file or directory
libnvidia-ml.so.1 is located in /usr/lib/nvidia-current but i can't open it.
Also i'm using bumblebee because i have two graphics cards, an igp and my gt640m.
Anybody help me pls?
