nn.test() fails: Kmeans - invalid arguments (CudaLongTensor) #1311

Open abachaa opened 6 years ago

Hi, I installed cltorch on Ubuntu 16.04 using this distro https://github.com/hughperkins/distro-cl as luarocks install cltorch is no longer supported.

I got this error when I run nn.test(): luajit -l nn -e 'nn.test()'

/.luarocks/share/lua/5.1/nn/Kmeans.lua:147: invalid arguments: CudaTensor CudaLongTensor CudaTensor number expected arguments: CudaTensor | [CudaTensor] [CudaTensor] CudaTensor index

=> I updated torch and nn, but it doesn't solve the problem: luarocks install torch && luarocks install nn

Any suggestions? Thanks!
