Nervana Systems have Neon which is an open source Python-based language and set of libraries for developing deep learning models. Neon is super fast, super powerful, and super easy to use!
github: https://github.com/NervanaSystems/neon
I tried building this source on my machine as below:
- OS: Ubuntu 16.04
- GPU: CUDA 8.0
- NVDIA SMI – 375.20
Build Source:
- $ git clone https://github.com/NervanaSystems/neon
- $ cd neon
- $ make
How to run:
- $ pwd
- Note: Make sure you are in the neon folder
- neon$ . .venv/bin/activate
- This will open python virtualenv session for you
- You can run jupyter notebook here as
- $ jupyter notebook
- To close active neon session in virtualenv do the following:
- neon$ deactivate
Here are few problems I had along with their solution:
PROBLEM [1]
c++: error: unrecognized command line option ‘-Wdate-time’
c++: error: unrecognized command line option ‘-fstack-protector-strong’
c++: error: unrecognized command line option ‘-Wdate-time’
c++: error: unrecognized command line option ‘-fstack-protector-strong’

Makefile:116: recipe for target ‘.venv2/bin/activate’ failed
make: *** [.venv2/bin/activate] Error 1
SOLUTION:
- You would need to change gcc/g++ to 5.0 or above
PROBLEM [2]
unable to execute ‘clang++’: No such file or directory
unable to execute ‘clang++’: No such file or directory
unable to execute ‘clang++’: No such file or directory
Command “/home/avkash/toolkit/neon/.venv2/bin/python2.7 -u -c “import setuptools, tokenize;file=’/tmp/pip-U3oScE-build/setup.py’;f=getattr(tokenize, ‘open’, open)(file);code=f.read().replace(‘\r\n’, ‘\n’);f.close();exec(compile(code, file, ‘exec’))” install –record /tmp/pip-le8M0S-record/install-record.txt –single-version-externally-managed –compile –install-headers /home/avkash/toolkit/neon/.venv2/include/site/python2.7/nervana-aeon” failed with error code 1 in /tmp/pip-U3oScE-build/
Makefile:157: recipe for target ‘aeon_install’ failed
SOLUTION:
You would need to install clang to solve this problem as below:
$ sudo apt-get install clang
PROBLEM [3]:
loader/src/util.hpp:24:10: fatal error: ‘sox.h’ file not found
#include <sox.h>
Solution:
You would need to install sox libraries as below:
- $ sudo apt-get install libsox-fmt-all libsox-dev sox
Successful Build:
neon$ make
