如何将二维 numpy 数组保存到文本文件中

Question

I have this following code where "final" is an array [ 2. 75.75 73.875 93.625 7. 29.369]

now, how do I save the reshaped 2d matrix "fin" as a .txt file.

and if it is saved as a text file, how do I get back the same as a matrix in a different program, where I open the text file

    fin = numpy.reshape(final,(-1,3))
    print(fin)
    print(fin[0][2])

output of above code

    [[ 2.    75.75  73.875]
     [93.625  7.    29.369]]
    73.875

Answer 1

To save the file : you can use : np.savetxt("file.csv", final, delimiter=",") .here's the documentation if you want to modify more parameters

To open it in another file : new_array = np.genfromtxt("file.csv", delimiter=",") .here's the documentation

Answer 2

您可以尝试以下方法:)

np.savetxt("final.csv", final, delimiter=",")
