omicverse.pp.anndata_to_CPU

omicverse.pp.anndata_to_CPU(adata, layer=None, convert_all=True, copy=False)[source]

Migrate AnnData objects from GPU back to CPU memory after analysis.

Parameters:

  • adata – AnnData object containing single-cell data on GPU.

  • layer (default: None) – Specific layer to convert back to CPU. Default: None (all layers).

  • convert_all (default: True) – Whether to convert all arrays to CPU. Default: True.

  • copy (default: False) – Whether to create a copy during conversion. Default: False.

Returns:

The function modifies adata in place by moving data from GPU to CPU memory.

Return type:

None

Examples

>>> import omicverse as ov
>>> # After GPU processing, move back to CPU
>>> ov.pp.anndata_to_CPU(adata)
>>> # Convert only specific layer
>>> ov.pp.anndata_to_CPU(adata, layer='scaled', convert_all=False)
