running in 32 bit virtualbox

[kohlisimranjit]

Greetings, I am trying to run Caffe on virtual box with ubuntu 14.04 32 bit. I installed cuda toolkit & drivers via cuda_6.5.14_linux_32.run. I also have installed all the dependencies as stated. I am able to build it sucessfully. But the tests are failing (console o/p pasted below). How can one go about to use cafee in virtual box instance.

caffe will crash on 32 bit most often and wont compile properly. install 64bit ubuntu and caffe libraries.

Hmm, I successfully installed Caffe on Ubuntu 32bit (actually a few tests were failed, 4 or 7, as I suppose due to accuracy of calculations because I saw the same errors in other people questions), and I use it in my C++ program. Should I worry?

Please ask installation questions on the caffe-users mailing list.
