Python中保存和读取numpy array类型变量

Python中保存和读取numpy array类型变量

保存：

    import numpy as np
    predict_label = np.array([0,1,0,1])
    np.save('predict_label.npy',predict_label) 

拓展：如果想在matlab中加载数据，则保持为mat格式数据

from scipy import io
io.savemat('predict_label.mat',{'predict_label':predict_label})

读取

    import numpy as np
    predict_label = np.load('predict_label.npy')
