python+anaconda+pycharm工具包安装

更新额外包

$ conda update conda

更新pip

python -m pip install --upgrade pip

更新所有

conda update --all

安装ffmpeg

conda install ffmpeg

不存在该包，用anaconda search

[Anaconda2] C:\Users\xwei>anaconda search -t conda ffmpeg

groakat/ffmpeg-dev | 2.4.3 | conda | linux-64, win-64,osx-64

[Anaconda2] C:\Users\xwei>conda install -c https://conda.anaconda.org/groakat ffmpeg-dev

安装theano

source for win-install

source for install

[Anaconda2] C:\Users\xwei\Desktop\lstm-test>

jaikumarm/theano          |    0.8.2 | conda           | linux-64, win-32, win-64, linux-32, osx-64  : Optimizing compiler for evaluating mathematical expressions on CPUs and GPUs.

[Anaconda2] C:\Users\xwei\Desktop\lstm-test>


[Anaconda2] C:\Users\xwei\Desktop\lstm-test>python lstm.py



[Anaconda2] C:\Users\xwei> conda install mingw libpython

之后即可以在anaconda Prompt 里面直接调用theano ，包括g++

运行LSTM Networks for Sentiment Analysis 明显快了很多很多，直接在cpu下运行纯python代码，一两分钟才出来第一次迭代， 安装之后，运行c代码的时候，基本上两三秒一次迭代。

安装出现Anaconda Python installation error

解决参考stackoverflow

First, open a DOS prompt and admin rights. Then, go to your Anaconda2\Scripts folder.
