dig
Structure
- dig, python package folder
- notebooks, python notebook folder to demonstrate how can we use dig
Install
要安装 dig 到 python 环境中，需要按以下命令
cd /your-path-to/dig # (not dig/dig)
pip install -e . # "-e" means editableUse Python in Matlab
Common Data Format
*.npy, *.npz file formats are common in python/numpy community; while *.mat file format is common in matlab community. Matlab has professional documents to demonstrate how to use Python from Matlab and vice.
from scipy.io import loadmat
annots = loadmat('*.mat')% In Matlab, npy-matlab module could help you read and write npy format files, https://github.com/kwikteam/npy-matlab
a = rand(5,4,3);
writeNPY(a, 'a.npy');
b = readNPY('a.npy');% In Matlab, configure Python environment https://ww2.mathworks.cn/help/matlab/ref/pyenv.html
pyenv % 返回当前默认的 Python 环境
pyenv('Version', 3.8) % 寻找当前电脑上的对应版本的 Python 环境
pyenv('Version', path-to-your-python-executable) % 寻找当前电脑上的对应路径的 Python 环境
if count(py.sys.path,'path-to-your-package') == 0
insert(py.sys.path,int32(0),'path-to-your-package');
end
