ノート/VRAE-y0astを試す 2017-05-05

まず theano-VAE by y0ast のインストール・テストから

y0astのVAE

https://github.com/y0ast/Variational-Autoencoder

This is an improved implementation of the paper 
[Stochastic Gradient VB and the Variational Auto-Encoder]
(http://arxiv.org/abs/1312.6114) by D. Kingma

theanoでの「-fPIC を付けて再コンパイル」というエラー

Theanoのインストールはpip install theanoでよいのだが、実行しようとするとエラー:

これに対して、TheanoをpyenvでインストールしたPython3.4.2で動かそうとしたら「PICオプションつけて再コンパイルしろよ」と怒られた時にやった対処メモ を試してみる。

env PYTHON_CONFIGURE_OPTS="--enable-shared" pyenv install 3.5.1
pyenv: /home/yamanouc/.pyenv/versions/3.5.1 already exists
continue with installation? (y/N) y
Installing Python-3.5.1...
Installed Python-3.5.1 to /home/yamanouc/.pyenv/versions/3.5.1

これでよかったみたい。

その他、python 2⇒3 のトラブル(修正点)
