fbcunn imagenet example synchronize error

[Yunhun Jang]

Hi, everyone.

I'm trying to use fbcunn imagenet example now.

However, I have trouble running the code.

When I execute the example using command such as

th main.lua -data /my/path/to/ilsvrc2014 -nGPU 2 

it gives me the error looks like following:

/home/vision/torch/install/bin/luajit: /home/vision/torch/install/share/lua/5.1/threads/init.lua:271: 

[thread 1 callback] /home/vision/torch/install/share/lua/5.1/torch/File.lua:254: unknown object

[thread 2 callback] /home/vision/torch/install/share/lua/5.1/torch/File.lua:254: unknown object

stack traceback:

[C]: in function 'error'

Are there anyone who knows why this happen?

Whenever you want to debug, use the script with the flag: -nDonkeys 0

In your case: th main.lua -data /my/path/to/ilsvrc2014 -nGPU 2 -nDonkeys 0

It will give you a clearer stack-trace of what's going on.

Thanks, smth

It was the problem of trainCache.t7

It works well now!
