Neural networks, regression and feature learning in Clojure.
Cortex has been developed by ThinkTopic in collaboration with Mike Anderson.
https://groups.google.com/forum/#!forum/clojure-cortex
All libraries are released on clojars. Cortex is not 1.0 yet preliminary and you should expect quite a few things to change over time but it should allow you to train some initial classifiers or regressions. Note that the save format has not stabilized and although we do just save edn data in nippy format it may require some effort to bring versions of saved forward.
Design is detailed here: Cortex Design Document
Please see the various unit tests and examples for training a model. Specifically see: mnist verification
Also, for an example of using cortex in a more real-world scenario please see: mnist example.
hdf5 import of major keras models (vgg-net). This requires each model along with a single input and per-layer outputs for that input. Please don't ask for anything to be supported unless you can provide the appropriate thorough test.
Recurrence in all forms. There is some work towards that direction in the compute branch and it is specifically designed to match the cudnn API for recurrence. This is less important at this point than running some of the larger pre-trained models.
Speaking of larger nets, multiple GPU support and multiple machine support (which could be helped by the above graph based description layer).
Profiling GPU system to make sure we are using as much GPU as possible in the single-gpu case.
Better data import/visualization support. We have geom and we have a clear definition of the datasets, now we need to put together the pieces and build some great visualizations as examples.
lein test in both cortex and compute. The various unit tests train various models.$ sudo apt install nvidia-cuda-toolkit
reboot
Install cuDNN and copy the cuDNN files to the corresponding folders in the local cuda installation (probably at /usr/local/cuda). For reference, follow the “Installing cuDNN” section here.
To check everything is working, run $ nvidia-smi
You should now have cuda8.0 installed. Current master is 8.0, so if you're running 7.5 you will need to change the javacpp dependency in your project file of the mnist Example.
These instructions follow the gpu setup from Tensor Flow, i.e.:
Install coreutils and cuda:
$ brew install coreutils
$ brew tap caskroom/drivers
$ brew cask install nvidia-cuda
Add CUDA Tool kit to bash profile
export CUDA_HOME=/usr/local/cuda
export DYLD_LIBRARY_PATH="$DYLD_LIBRARY_PATH:$CUDA_HOME/lib"
export PATH="$CUDA_HOME/bin:$PATH"
Download the CUDA Deep Neural Network libraries.
Once downloaded and unzipped, moving the files:
$ sudo mv include/cudnn.h /Developer/NVIDIA/CUDA-8.0/include/
$ sudo mv lib/libcudnn* /Developer/NVIDIA/CUDA-8.0/lib
$ sudo ln -s /Developer/NVIDIA/CUDA-8.0/lib/libcudnn* /usr/local/cuda/lib/
Should you see a jni linking error similar to this
