如何在 multiprocessing.shared_memory 中设置 ShareableList 列表的大小

如何解决如何在 multiprocessing.shared_memory 中设置 ShareableList 列表的大小

我使用以下代码定义了一个 ShareableList() 来存储字符串：

from multiprocessing import shared_memory

global_memory = shared_memory.ShareableList([""] * 10,name='my_mem')

global_memory[0] = "hello I'm a long string"

它返回：

ValueError: bytes/str item exceeds available storage

我预料到了这一点，因为在 documentation 示例中发生了同样的情况：

>>> from multiprocessing import shared_memory

>>> a = shared_memory.ShareableList(['howdy',b'HoWdY',-273.154,100,None,True,42])

>>> [ type(entry) for entry in a ]
[<class 'str'>,<class 'bytes'>,<class 'float'>,<class 'int'>,<class 'nonetype'>,<class 'bool'>,<class 'int'>]

>>> a[2]
-273.154

>>> a[2] = -78.5

>>> a[2]
-78.5

>>> a[2] = 'dry ice'  # Changing data types is supported as well

>>> a[2]
'dry ice'

>>> a[2] = 'larger than prevIoUsly allocated storage space'
Traceback (most recent call last):
  ...
ValueError: exceeds available storage for existing str

>>> a[2]
'dry ice'

len(a)
7

a.index(42)
6

a.count(b'howdy')
0

a.count(b'HoWdY')
1

a.shm.close()

a.shm.unlink()

del a  # Use of a ShareableList after call to unlink() is unsupported

但我的问题是，如何为列表中的每个元素添加更多空间，以便我可以存储更大的字符串？
