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?

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)
