Aqui veremos o que será necessário para executar o projeto BAYOU, desde os seus requisitos até a instalação e execução.

Requisitos:

• Linux (CLARO!)
• Maven
• Mavn-jansi
• Tensorflow
• Scikit-learn

Para o texto tornar extenso, assumirei que o ambiente Linux com Java, Python e Maven está devidamente instalado e configurado.

Instalando os pacotes Tensorflow e Scikit-learn

Com o ambiente python funcionando corretamente, utilize os comandos abaixo como super-usuário para resolver as dependências python do projeto Bayou:

# pip install tensorflow
# pip install scikit-learn

Para testar o funcionamento adequado do tensorflow, utilize as instruções a seguir. Se o resultado for similar, significa que o ambiente python está devidamente configurado.

python
>>> import tensorflow as tf
>>> hello = tf.constant('Hello, TensorFlow!')
>>> sess = tf.Session()
>>> print(sess.run(hello))
b'Hello, TensorFlow!'

Agora efetue o download a partir do código fonte.

git clone https://github.com/capergroup/bayou.git

Após o download, siga o exemplo a seguir para resolver as dependências java:

cd bayou/tool_files/build_scripts
$ sudo ./install_dependencies.sh

A compilação é efetuada com o comando build:

./build.sh

Agora para executar o motor principal, entre na pasta out e execute o comando start_bayou.sh:

cd out/
$ ./start_bayou.sh

Agora crie um arquivo .java onde desejamos que a inteligência artificial atue, coloque a TAG FILEWRITE para escrita de arquivo utilizando BUFFER.

import java.io.*; 
import java.util.*; 
public class Test { 
   void write(File file, String toWrite) { 
       { 
               /// call:write type:FileWriter type:BufferedWriter 
       } 
   }   
} 

Agora utilize o comando synthesize para o sistema devolver o resultado do problema proposto:

./synthesize.sh exemplo/Test.java

Veja o resultado:
