我有一个 3d 天文表，我想将其写入文件。我通过将 3d numpy 数组转换为 astropy 表并添加一些列名来创建它。
这是我的表的示例输出。每行每列中的数组表示第三维。
m_star [14] m_bh [14] ... exit_flag [14]
float64 float64 ... float64
------------------------- ------------------------ ... --------------
3.9782e+32 .. 2.18801e+33 1.9891e+36 .. 1.9891e+38 ... 0.0 .. 0.0
3.9782e+32 .. 2.18801e+33 1.9891e+36 .. 1.9891e+38 ... 0.0 .. 0.0
3.9782e+32 .. 2.18801e+33 1.9891e+36 .. 1.9891e+38 ... 0.0 .. 0.0
3.9782e+32 .. 2.18801e+33 1.9891e+36 .. 1.9891e+38 ... 0.0 .. 0.0
3.9782e+32 .. 2.18801e+33 1.9891e+36 .. 1.9891e+38 ... 0.0 .. 0.0
3.9782e+32 .. 2.18801e+33 1.9891e+36 .. 1.9891e+38 ... 6.0 .. 6.0
我将 2d astropy 表写入文件的方式是
param_table.write(param.txt, format='ascii')
但是当我尝试将 3d astropy 表写入文件时，我收到错误：
Traceback (most recent call last):

关键是能够通过另一个模块读取文件并检索 astropy 表。
