numpy.save(file, arr)函数可以将单个数组保存到文件中。其中,file参数是保存文件的路径,arr参数是要保存的数组对象。保存的文件将使用.npy扩展名。 示例代码: 代码语言:txt 复制 import numpy as np arr = np.array([1, 2, 3, 4, 5]) np.save('array_data.npy', arr) numpy.savez(file, *args, ...
This is a simple 2-dimensional array that we’ll be able to save to a text file withnp.savetxt(). EXAMPLE 1: Save a Numpy array to a text file Here, we’ll start with a very simple example. We’re simply going to save our Numpy array data to a text file, and we’ll use al...
When you are using numpy.savetxt() function to save numy array into a text file, you my get this error: TypeError: Mismatch between array dtype ('<U31') and format specifier ('%.18e %.18e %.18e'). In this tutorial, we will introduce to you on how to fix
