python安装深度学习包theano,Pylearn2,scikit-neuralnetwork

我用的是anaconda环境

直接用anaconda安装

下面 两条命令:

anaconda search -t conda 包名

conda install -c https://conda.anaconda.org/conda-forge 包名

 

python2.7

1. 安装numpy, scipy, theano：

conda install -c https://conda.anaconda.org/conda-forge numpy

conda install -c https://conda.anaconda.org/conda-forge scipy

conda install -c https://conda.anaconda.org/conda-forge theano

 

2.安装Pylearn2

 　　conda install -c https://conda.anaconda.org/conda-forge Pylearn2

3.安装scikit-neuralnetwork

git clone https://github.com/aigamedev/scikit-neuralnetwork.git

cd scikit-neuralnetwork

python setup.py develop

 4.测试

conda install -c https://conda.anaconda.org/conda-forge nose

nosetests -v sknn.tests

结果报错:

解决办法:

从开发模式安装lasagne

git clone https://github.com/Lasagne/Lasagne.git

cd Lasagne

python setup.py install
