在 Python 中读取 npy 数据文件并导出为文本文件

Question

I have an array saved in a npy file and want to export it into readable text columns.我有一个保存在 npy 文件中的数组，并希望将其导出到可读的文本列中。

I did the following:我做了以下事情：

import numpy as np
data = np.load('D:/20190805_01_data.npy')

type(data ) gives numpy.ndarray type(data ) 给出numpy.ndarray

len(data) gives 1363 len(data)给出1363

data.ndim gives 3 data.ndim给出3

To export data I tried:要导出数据，我试过：

np.savetxt('D:/data.txt',data, delimiter=' ')

which does not work.这不起作用。

What is the correct solution?什么是正确的解决方案？

Answer 1

it seems that your data have one extra dimension似乎您的数据有一个额外的维度

data.shape
Out[4]: (1363, 1, 2)

You can do the following to remove this dimension :您可以执行以下操作来删除此维度：

data = np.squeeze(data)

and then save data to a .txt file.然后将data保存到 .txt 文件中。
