LETTER dataset directory


We have tested the following instructions under 9.10 Ubuntu Linux 64bit.
  1. Download Ubuntu 64bit from here and install it.
  2. Install required packages (as root): apt-get install build-essential ia32-libs rpm
  3. Download and install (as root) (dpkg -i libstdc++5_3.3.6-18_amd64.deb) the AMD64 version of libstdc++5
  4. Download the i386 version of libstdc++5
    Go to the download location and extract the package: dpkg --extract libstdc++5_3.3.6-18_i386.deb .
    Copy the extracted library (as root): cp ./usr/lib/ /usr/lib32
    Make a symlink (as root): ln -s /usr/lib32/ /usr/lib32/
  5. Download the Intel C++ compiler package from Extract the 700MB tgz and follow the install instructions. This installs the compiler, the MKL and IPP to /opt/intel/Compiler/XX.X/XXX/... on the system.
  6. Edit the /etc/ file by adding the following lines.
    Replace the XX with the current version code of the Intel toolchain. After that run ldconfig as root.
  7. Make a symlink (as root) ln -s /opt/intel/Compiler/XX.X/XXX/bin/intel64/icpc /usr/bin
  8. Make sure that the INTEL_PATH in the Makefile matches the installed version.
  9. Go to the directory of the ELF and do make. Done.

Quick start

For a first train run, please download the LETTER dataset directory from above and extract the content to the directory, where the executable ELF is located. Then type $./ELF LETTER t to start training. The output should look like this.
