[mlpack-git] [mlpack] Test programs failing on loading data from disk (#597)

[Ozair Shafiq]

I recently cloned the repository and tried to follow the build instructions given in README file and suggested by rcurtin to building with debug, profile = off, that will make the library execute faster for performance. I am compiling using the command 'cmake .. -DDEBUG=OFF -DPROFILE=OFF' and then installing by using 'sudo make install' in the build directory. Then, I run mlpack_test by ./mlpack_test -t FeedForwardNetworkTest and it fails. The error is

Running 3 test cases...
[FATAL] Cannot open file 'thyroid_train.csv'. 

unknown location(0): fatal error in "VanillaNetworkTest": std::runtime_error: fatal error; see Log::Fatal output
[FATAL] Cannot open file 'thyroid_train.csv'.

I try running ./mlpack_test -t AllkNNTest and it fails aswell with a similar error.

Running 21 test cases...

I was very hesitant to make a topic about this here because I think its a problem on my end. But I've been trying to compile and build this using the instructions given and all the data-set files actually do exist in the build folder. I tried changing file permissions of the build folder using chmod command and that didn't work and I am not an expert in linux, hence I don't know what I am doing wrong.

I tried asking for solution for this on the IRC channel for a couple days now and with no response, hence, I am making the topic here.

Regards.
