[英]Saving numpy array to file in a single line?
On the code bellow I want to save an array to a file in a single line using "numpy.savetxt" but I'm really not sure if I can get this result. 在下面的代码中,我想使用“ numpy.savetxt”将数组保存到一行中的文件中,但是我真的不确定是否可以得到此结果。
import numpy as np
if __name__ == '__main__':
array = np.array([[ 6, -2.86751284, -0.35808319, 1.79360812],
[ 6., -1.59351284, -0.02808319, -0.47039188],
[ 6., 0.51848716, 0.21791681, 0.17060812],
[ 6., 1.63251284, -0.12208319, 0.90460812],
[ 6., -0.26051284, 0.03991681, 1.33660812],
[ 6., 1.87948716, 0.43391681, 0.21960812],
[ 6., 2.52048716, 0.45191681, 1.44760812],
[ 6., 0.40448716, 0.04591681, 2.58360812],
[ 6., 1.81248716, 0.30391681, 2.62260812]], np.float32)
np.savetxt("img/file.txt", array, fmt="%.3d")
I wanted a result like "006, -002, -003, 001, 006, -001..." with all columns and lines in a single line in the file but separated by commas. 我想要一个结果,如“ 006,-002,-003、001、006,-001 ...”,所有列和行都在文件的一行中,但用逗号分隔。 Can I do it with "numpy.savetxt" or do I have to loop through array to get this result? 我可以使用“ numpy.savetxt”执行此操作,还是必须遍历数组才能获得此结果?
Thank you. 谢谢。
This should produce, what you want: 这应该产生您想要的:
np.savetxt("file.txt", array.flatten(), fmt="%.3d", newline = ", ")
cat file.txt
006, -002, 000, 001, 006, -001, 000, 000, 006, 000, 000, 000, 006, 001,
000, 000, 006, 000, 000, 001, 006, 001, 000, 000, 006, 002, 000, 001,
006, 000, 000, 002, 006, 001, 000, 002,
