This is a no-op for storages already in shared memory and for CUDA storages, which do not need to be moved for sharing across processes. Storages in shared memory cannot be resized. Note that to mitigate issues like `this `_ it is thread safe to call this function from multiple threads on the same object. It is NOT thread safe though to call any other function on self without proper synchronization. Please see :doc:`/notes/multiprocessing` for more details. .. note:: When all references to a storage in shared memory are deleted, the associated shared memory object will also be deleted. PyTorch has a special cleanup process to ensure that this happens even if the current process exits unexpectedly. It is worth noting the difference between :meth:`share_memory_` and :meth:`from_file` with ``shared = True`` #. ``share_memory_`` uses `shm_open(3) `_ to create a POSIX shared memory object while :meth:`from_file` uses `open(2) `_ to open the filename passed by the user. #. Both use an `mmap(2) call `_ with ``MAP_SHARED`` to map the file/object into the current virtual address space #. ``share_memory_`` will call ``shm_unlink(3)`` on the object after mapping it to make sure the shared memory object is freed when no process has the object open. ``torch.from_file(shared=True)`` does not unlink the file. This file is persistent and will remain until it is deleted by the user.

If ``shared`` is ``True``, then memory is shared between all processes. All changes are written to the file. If ``shared`` is ``False``, then the changes on the storage do not affect the file. ``size`` is the number of elements in the storage. If ``shared`` is ``False``, then the file must contain at least ``size * sizeof(Type)`` bytes (``Type`` is the type of storage). If ``shared`` is ``True`` the file will be created if needed. Args: filename (str): file name to map shared (bool): whether to share memory (whether ``MAP_SHARED`` or ``MAP_PRIVATE`` is passed to the underlying `mmap(2) call `_) size (int): number of elements in the storage z/from_file can only be called on derived classesr) rrrrrrHr7r8rB)r]rrr@r$rs r'rzTypedStorage.from_filezs^( $% , PQ Q(22 fdU\\%?%? %JJ ?3r)c,tj|i|Sr!)rrrcs r'rzTypedStorage._expireds&&777r)c:|jj|i|Sr!)rrtr#s r'rtzTypedStorage._write_files 0t$$00$A&AAr)c:|jj|i|Sr!)rr{r#s r'r{zTypedStorage._set_from_file 3t$$33TDVDDr)c:|jj|i|Sr!)rr}r#s r'r}zTypedStorage._set_cdatas /t$$//@@@r)c:|jj|i|Sr!)rrr#s r'rzTypedStorage._share_cuda_s 1t$$114B6BBr)c6t|jSr!)r _is_sharedr-s r'rzTypedStorage.is_shareds#%  r)c6|jjSr!)rrr-s r'rUzTypedStorage._is_shareds$$..00r)c@tjj|i|Sr!)rHrrrcs r'rzTypedStorage._new_shared_cudas##44dEfEEr)cn|jj|i|\}}}||||jzfSr!)rrXr8)r$r%r&manager_handlestorage_handler@s r'rXz!TypedStorage._share_filename_cpu_sH 7D ! ! 6 6 G G    ~tt7I7I7K/KKKr)c:|jj|Sr!)rrrr-s r'rrzTypedStorage._shared_decrefs ,,. r)c@tjj|i|Sr!rHrrkrls r'rmz!TypedStorage._release_ipc_counter##==tNvNNr)c:|jj|i|Sr!)rrr#s r'rzTypedStorage._shared_increfrQr)cj|jj|i|\}}|||jzfSr!)rrZr8)r$r%r&fdr@s r'rZzTypedStorage._share_fd_cpu_s<74((77HHD44--////r)c|jtvryt|j}|jjdddtj j fvry|jjdk(rtn#tt|jj} t||S#t$rYywxYw)NrrErM) rBrrrCrHr,r-getattrAttributeError)r$ storage_namers r'rz&TypedStorage._get_legacy_storage_classs ::79 913DJJ? ;;      HH 2 2 4 $  [[%%.EGE4;;CSCS4T  6<0 0  s, B88 CCrBrA)Fr!)r8rr9z_Optional[bool]r?)rBr@r9rr>z&Union[_StorageBase, TypedStorage, str])rrr9rr>r r=rCrD)arErFrGrrHrrJrrrrr(rrr3rr.rr5rr3rr:r>rrCrErMrIrOr8rRr rrrrrrrrrr r#r.rr1rrr@rr&r%rrTr,rVrwr0rIrryrdr5r rrrrrrrrrr r rrrrrrrrtr{r}rrrUrrXrrrmrrZrrKrLs@r'rrs Iu,0L)0  ..
