import_extension_from_bytes#

scikitplot.cython.import_extension_from_bytes(data, *, module_name, artifact_filename, temp_dir=None, key=None)[source]#

Import an extension module from raw artifact bytes.

Parameters:

databytes: Raw contents of a compiled extension artifact (.so / .pyd).
module_namestr: Module name the artifact was compiled for (init symbol name).
artifact_filenamestr: Filename to use when writing the artifact (must end with a valid extension suffix). This must be a simple filename (no directories).
temp_dirstr or os.PathLike or None, default=None: Directory to place the hash-scoped artifact file. If None, a platform temp directory is used.
keystr or None, default=None: Optional cache key to attach to the loaded module.

Returns:

types.ModuleType: Imported extension module.

Raises:

ValueError: If artifact_filename is invalid.
OSError: If a conflicting artifact already exists at the deterministic path.
ImportError: If the module cannot be loaded.

Parameters:

data (bytes)
module_name (str)
artifact_filename (str)
temp_dir (str | PathLike[str] | None)
key (str | None)

Return type:

ModuleType

Notes

Python extension modules cannot be imported directly from memory; the artifact must exist as a file on disk. This function writes the provided bytes to a deterministic location (by content hash) under temp_dir and imports it.
