The error is "cannot find any image file in the given directory". Could you make sure that you set the image directory DATA_ROOT correctly?

Same here, fresh install following the README on the latest MacBook Pro.

DATA_ROOT=./datasets/facades name=facades_generation which_direction=BtoA th train.lua

fails with the same error, and I confirmed ls ./datasets/facades returns test/ train/ val/.

[Flipajs]

I had the same problem.
Adding env before whole command hleped.

env DATA_ROOT=./datasets/facades name=facades_generation which_direction=BtoA th train.lua

Ah, there was an obscure error before that:

/tmp/lua_f46sBl: line 1: gfind: command not found

So I installed gfind with brew install findutils and this issue was solved. (You might also need to install coreutils as well)

Maybe install script needs to take care of this?

[kenn]

I had another error saying module 'cunn' not found:No LuaRocks module found for cunn after this and I had to:

luarocks install clnn

Then I had another error that says

Please install cltorch from https://github.com/hughperkins/distro-cl

and lastly I found this:

$ git clone --recursive https://github.com/hughperkins/distro -b distro-cl ~/torch-cl
$ cd ~/torch-cl
$ bash install-deps

So it won't work on macOS Sierra yet? :(

[ilsang]

I'm newbie.
I had same error when set path contains tif image files.
But when I set path contains jpg image files, there wasn't problem.
Is it impossible to import tif image files?

[junyanz]

Hi ilsang, It seems that "image.load" doesn't work for TIF format. You can find a related discussion at stackoverflow. You can also convert TIF to JPG/PNG offline.

Im having same issue with gfind and gwc but installing coreutils throws up an error installing (findutils seems to install ok)

It seems that all I had to do was upgrade to Mac OSX 10.12 and the latest xCode and it allowed me to install the xcode command line tools and coreutils so the above errors stopped.

brew link --overwrite coreutils fixed the link error

Now it seems to be able to run the train command on the cpu (its been going for the last 12 hours)
