loadNpy

loadNpy(fileName)

filename is a string indicating the path and name of an .npy file.

Load an .npy (Python Numpy) binary file and convert it into a DolphinDB vector or matrix. NaN in the .npy file is converted into NULL in DolphinDB.

Right now the function only works for .npy files with numerical data.

Save .npy files in Python:

import numpy as np
np.save("intVec.npy", np.array([5,6,1,3,4,8]))
np.save("doubleMat.npy", np.array([[1.5,5.6,-7.87],[-1.0,3.4,4.5]]))

Load .npy files in DolphinDB:

loadNpy("intVec.npy");
// output
[5,6,1,3,4,8]

loadNpy("doubleMat.npy");
