error of loading torch after install

[Yao Lu]

Hi,

After I installed a local Torch on a server, I typed

th -ltorch

and got

could not load torch, skipping

/home/lu033/torch/install/share/lua/5.1/torch/init.lua:13: cannot load '/home/lu033/torch/install/lib/lua/5.1/libtorch.so'

stack traceback:

[C]: in function 'require'

/home/lu033/torch/install/share/lua/5.1/torch/init.lua:13: in main chunk

[C]: in function 'require'

Then I typed

luajit -llibtorch

and got

luajit: error loading module 'libtorch' from file '/home/lu033/torch/install/lib/lua/5.1/libtorch.so':

/home/lu033/torch/install/lib/libTH.so.0: undefined symbol: THDoubleVector_cadd_AVX2

stack traceback:

What is wrong here? How should I fix it?
