Neural-style: Clearer installation instructions?

[bestguy]

This is more of a luarocks & torch issue, but it's really not clear how to run this project if you are not a Lua expert :-)

Installing any of the dependencies via luarocks on MacOSX:

luarocks install ***whatever***

Error: No results matching query were found.

I ran into the same problem on Linux, maybe the luarocks folder (cache) is read only or owned by root.

Try following the instructions to install Torch from their site first (wget then install.sh), then use the built-in luarocks.

[bestguy]

Thanks for the help, trying now.

Have to laugh that even use built-in luarocks is confusing me :-), I see 10 luarocks in my torch dir:

./build/exe/luajit-rocks/luarocks
./build/exe/luajit-rocks/luarocks/src/bin/luarocks
./build/exe/luajit-rocks/luarocks/src/luarocks
./exe/luajit-rocks/luarocks
./exe/luajit-rocks/luarocks/lfw/lua/luarocks
./exe/luajit-rocks/luarocks/src/luarocks
./install/bin/luarocks
./install/etc/luarocks
./install/lib/luarocks
./install/share/lua/5.1/luarocks

If you run install/bin/luarocks it'll install things in that local directory.

Got it, thanks for this. Closed the issue, but if you happen to know the resolution to this loadcaffe installation issue on OSX would appreciate the help:

-- Could NOT find PROTOBUF (missing:  PROTOBUF_LIBRARY PROTOBUF_INCLUDE_DIR) 
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
PROTOBUF_LIBRARY (ADVANCED)
    linked by target "loadcaffe" in directory /tmp/luarocks_loadcaffe-1.0-0-5782/loadcaffe

[bestguy]

Got it. For other's reference, fixed by:

brew install protobuf

@bestguy thank! you saved my day.

Hi everyone,
I've run into the same problem, I wonder if anyone knows what is the issue.
So basically I'm installing loadcaffe on cluster with NO root access. I could install the protobuf successfully( luarocks install protobuf), however, when I try to install the loadcaffe itself I get the following error:

-- Could NOT find PROTOBUF (missing: PROTOBUF_LIBRARY PROTOBUF_INCLUDE_DIR)
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
PROTOBUF_LIBRARY (ADVANCED)
linked by target "loadcaffe" in directory /tmp/luarocks_loadcaffe-1.0-0-73/loadcaffe

-- Configuring incomplete, errors occurred!
See also "/tmp/luarocks_loadcaffe-1.0-0-73/loadcaffe/build/CMakeFiles/CMakeOutput.log".
See also "/tmp/luarocks_loadcaffe-1.0-0-73/loadcaffe/build/CMakeFiles/CMakeError.log".
make: *** No targets specified and no makefile found. Stop.

Error: Build error: Failed building.

@hhassanzadeh I think you should check the "Advanced" check box before the "Add Entry" button. After that, you can see all the configurations related to protobuf, protoc and protobuf-lite. You can then specify each lib file accordingly, both for release and debug. It worked for me when I tried to compile Caffe after bumping into the same problem, though.

@hhassanzadeh , did you manage to solve this issue?
I get the same error too.

Hey, no I could not do that .

set the following env variables:
CMAKE_INCLUDE_PATH = [YOUR_PATH]protobufsrcgoogleprotobuf # which points at the bottom of your include path.
CMAKE_LIBRARY_PATH = [YOUR_PATH]protobufsrc.libs #which should contain "libprotobuf" "libprotobuf-lite" "liteprotoc" .lib files.

You might also need to add protobuf ([YOUR_PATH]protobufsrc) to your $PATH system variable if you are on Windows.

Now run cmake:
cmake .. -G "MSYS Makefiles" # Replace 'MSYS' if you are using a different generator.
