1 | +para execução do script é necessário executar as seguintes linhas no terminal | |
2 | + | |
3 | +sudo apt-get install python-pip python-dev build-essential | |
4 | +sudo pip install --upgrade pip | |
5 | +sudo pip install gdal scikit-image pyyaml | |
6 | + | |
7 | +É necessário instalar tbm o YAML no PHP: | |
8 | + | |
9 | +sudo pecl install yaml | |
10 | + | |
11 | +Depois de instalado é necessário incluir no php.ini: | |
12 | + | |
13 | +extension=yaml.so | |
14 | + | |
15 | +e reiniciar o apache | |

19 | +O script lê os parâmetros a partir de um arquivo yaml cujo nome é definido ao executar o programa | |
20 | + | |
21 | +Para executar o arquivo é necessário invocá-lo no terminal: | |
