Not enough space on partition mounted at /

[itanon]

I'm on Kali 2016.2 live usb installation and I'm trying to install Nvidia cuda toolkit, so I've downloaded the .Run file, make it executable then issued the .Run command.
Scrolled the EULA contract, set the directory for installation and confirmed....
The installation seems to starts but then, it stops giving me the message:
"
Not enough space on partition mounted at/.
Need 2308316160 bytes

Not enough space on partition mount at
/tmp.
Need 2114567168 bytes.

Disk space check has failed. Installation cannot continue"

On other configuration I've resolved this problem, issuing the command : "mount -o bind /var/tmp /tmp"
Now, this doesn't work so I'm stucked.
Anyone know how to solve it?

you need 2 gig of space, since live usb setup a drive from the ram, you will need a beefy amount of ram to have it work, you should try in a VM or a hard drive install could fix the issue. you could also run du -h for your disk usage or df -h for your disk free space to have an idea of what happen

here's the output of "df -h" command:

as you see, your live image have 4.4g of hdd available so yes you could fill it quickly, you should work in vm or on an hdd install, maybe a peristant usb could also work not sure!
