Ubuntu14.04 / 16.04、Python、[GPU](https://cloud.tencent.com/product/gpu?from=10680)、ソースからのビルドに基づく
export LD_LIBRARY_PATH=/usr/local/cuda/lib64/:$LD_LIBRARY_PATH
MXNetコア共有ライブラリ(C ++ソースコードから* libmxnet.so *)をコンパイルします。
Minimum Requirements:
# Step 1 Install build tools and git.
$ sudo apt-get update
$ sudo apt-get install -y build-essential git
# Step 2 Install OpenBLAS.
$ sudo apt-get install -y libopenblas-dev
# Step 3 Install OpenCV.
$ sudo apt-get install -y libopencv-dev
# Step 4 Download MXNet sources and build MXNet core shared library.
$ git clone --recursive https://github.com/dmlc/mxnet
$ cd mxnet
$ make -j $(nproc) USE_OPENCV=1 USE_BLAS=openblas USE_CUDA=1 USE_CUDA_PATH=/usr/local/cuda USE_CUDNN=1
# Step 1 Install prerequisites - python setup tools and numpy.
$ sudo apt-get install -y python-dev python-setuptools python-numpy
# Step 2 Build the MXNet Python binding.
$ cd python
$ sudo python setup.py install
# Step 3 Validate the installation by running simple MXNet code.
>>> import mxnet as mx
>>> a = mx.nd.ones((2,3), mx.gpu()) #GPUで2×3マトリックスを作成します
>>> b = a *2+1 #行列a×2の各要素+1>>> b.asnumpy()array([[3.,3.,3.],[3.,3.,3.]], dtype=float32)
