粉碎:如何在PyTables储存一只高温多面阵列?
原标题:Python: how to store a numpy multidimensional array in PyTables?

我如何在使用便携式导弹的HDF5档案中设置一个冷静的多层面阵列?

从我能够告诉我的情况来看,我可以把一个阵列放在一个表桌上。

我还需要储存一些有关这一阵列的信息,并能够进行数学计算。

任何建议?

最佳回答

也许可以比较简单,但正如我所知,这是你如何做的:

import numpy as np
import tables

# Generate some data
x = np.random.random((100,100,100))

# Store "x" in a chunked array...
f = tables.open_file( test.hdf ,  w )
atom = tables.Atom.from_dtype(x.dtype)
ds = f.createCArray(f.root,  somename , atom, x.shape)
ds[:] = x
f.close()

如果你想具体说明使用压缩机,请查阅<代码>表。 Filters 。 E.g.

import numpy as np
import tables

# Generate some data
x = np.random.random((100,100,100))

# Store "x" in a chunked array with level 5 BLOSC compression...
f = tables.open_file( test.hdf ,  w )
atom = tables.Atom.from_dtype(x.dtype)
filters = tables.Filters(complib= blosc , complevel=5)
ds = f.createCArray(f.root,  somename , atom, x.shape, filters=filters)
ds[:] = x
f.close()

这可能更简单一些...... 除表类数据外,我有的长时期使用<代码>pytables。

<Note: with pytables 3.0,f.createCArray>/code> 改为f.create_carray。 它还可以直接接受这些阵列,而不具体说明atom,

f.create_carray( / ,  somename , obj=x, filters=filters)
