Hello, NoKot333. Do you use any Numpy functions?

I can confirm, I have seen error 1672 when returning a numpy array which is generated by the python script

 

in the following, I write a 2d buffer to the python node, extract the first column of this 2d buffer, convert this column vector to a numpy array and return as 1d array of doubles "y".

 

 

import numpy as np
def return_cm(data):

    y = data[:, 0]
    X = data[:, 1:]

    y = np.array(y)
    return y

 

 

 

the length of the y-vector can be manipulated by choosing a different number of rows, in the following screenshot 1000:

Error 1672 does halt the .vi, when the numbers of rows in this vector is bigger ~ 10.000 , but will work corretly if less e.g. 1000

There are some Numpy functions, which are not supported by LabVIEW.
