Binary file incompatibility?

Hi, thank you for great work. It runs faster than original torch on Xeon.

However, I'm having one trouble while trying to load trained .t7 files. These .t7 files are trained on GPGPU torch but converted for CPU. Original torch on CPU (without GPGPU) works well with these .t7 files. However, Intel torch shows following error message.

$ th ...

/home/.../torch/inteltorch/install/bin/lua: .../torch/inteltorch/install/share/lua/5.2/torch/
File.lua:301: Failed to load function from bytecode: binary string: not a precompiled chunk

        .../torch/inteltorch/install/share/lua/5.2/torch/File.lua:369: in function 'readObject'

Any idea? Thanks.

hi kmarukawa
Thanks for your feedback. When runing imagenet classification, we could load the snapshot files(.t7 files) without any error.
From your log ,the luajit version you installed is 5.2. Could you please install luajit2.1(the default version) and try again?

Hi xhzhao,
Thank you for the suggestion. You are right. I unfortunately compiled it with lua 5.2 while I was trying to port GPGPU program into this Intel Torch. I recompiled Intel torch from scratch again. It works fine. Thanks.
