Python savetxt写为int

Question

我正在尝试将数组写入文本文件，我希望每个元素都被写为int类型。

我正在使用

np.savetxt(outfile_name, array, comments = '')

写出文件。我使用

将array从float转换为int

array = array.astype(int)

当我在程序中打印array时，数组显示为int，但是当我将其写入文本文件时，文件看起来像：

0.000000000000000000e+00 1.000000000000000000e+00 1.000000000000000000e+00 1.000000000000000000e+00 1.000000000000000000e+00
1.000000000000000000e+00 1.000000000000000000e+00 0.000000000000000000e+00 1.000000000000000000e+00 1.000000000000000000e+00
1.000000000000000000e+00 1.000000000000000000e+00 1.000000000000000000e+00 1.000000000000000000e+00 0.000000000000000000e+00
1.000000000000000000e+00 1.000000000000000000e+00 1.000000000000000000e+00 0.000000000000000000e+00 1.000000000000000000e+00
1.000000000000000000e+00 1.000000000000000000e+00 0.000000000000000000e+00 0.000000000000000000e+00 0.000000000000000000e+00

Answer 1

您是否尝试过按the documentation指定格式？

np.savetxt(outfile_name, array, fmt="%d", comments='')
                              # ^ format as signed decimal integer

这使用标准format specification mini-language。
