loadNpy
Syntax
loadNpy(fileName)
Arguments
filename is a string indicating the path and name of an .npy file.
Details
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.
Examples
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");
#0 | #1 | #2 |
---|---|---|
1.5 | 5.6 | -7.87 |
-1 | 3.4 | 4.5 |
