python - 如何将 3d astropy 表写入文件

Question

我有一个 3d astropy 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。

这是我的表格的示例输出。每行每列内的数组表示第三维。

       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):
  File "/Users/astromonerd/HLX1/src/make_dat.py", line 86, in <module>
    dat_table.write(run_dir + '/' + 'dat.txt', format='ascii')

TypeError: unhashable type: 'list'

重点是能够通过另一个模块读取文件并检索 astropy 表。

我能够使用 hdf5 格式做到这一点:

param_table.write(param.h5, format='hdf5')
