I m trying to use a matrix to compute stuff The code is this import numpy as np some code mmatrix np zeros nrows ncols print mmatrix 0 0 but I get data type not understood and it works if I do it from terminal

[python] data type not understood

Try:

mmatrix = np.zeros((nrows, ncols))

Since the shape parameter has to be an int or sequence of ints

Otherwise you are passing ncols to np.zeros as the dtype.
