将二维数组另存为 txt 文件

Question

In my simulation i compute an array x with "dimensions"

np.shape(x)

---> (50,80)

To my understanding this is a two dimensional array with 50 rows and 80 columns. When i try save x as a csv file i get an error:

np.savetxt('values.csv',[x])

--> ValueError: Expected 1D or 2D array, got 3D array instead

How can x be a 3D array? Its described by two indices (row,column) and therefore is two dimensional or not?

Answer 1

Remove the square brackets from x . This is converting it to a list of one item - the array.

np.savetxt('values.csv',x)
