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

stack overflow

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

anaconda search -t conda theano

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>

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

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

WARNING (theano.configdefaults): g++ not detected ! Theano will be unable to execute optimized C-implementations (for both CPU and GPU) and will default to Python implementations. Performance will be severely degraded. To remove this warning, set Theano flags cxx to an empty string.

• [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.

conda update conda

and allow all updates. One of the updates should be menuinst.

Then, change to the Anaconda2\Lib directory, and type in the following command:

..\python _nsis.py mkmenus

Wait for this to complete, then check your Start menu for the new shortcuts.
