Citing the docstring for pyassimp's export function:

>>> help(pyassimp.export)
Help on function export in module pyassimp.core:

export(scene, filename, file_type=None, processing=8)
    Export a scene. On failure throws AssimpError.

    Arguments
    ---------
    scene: scene to export.
    filename: Filename that the scene should be exported to.  
    file_type: string of file exporter to use. For example "collada".
    processing: assimp postprocessing parameters. Verbose keywords are imported
                from postprocessing, and the parameters can be combined bitwise to
                generate the final processing value. Note that the default value will
                triangulate quad faces. Example of generating other possible values:
                processing = (pyassimp.postprocess.aiProcess_Triangulate | 
                              pyassimp.postprocess.aiProcess_OptimizeMeshes)

In your case, this means you should call the function with the file_type gltf2, like so:

pyassimp.export(scene,'444.gltf','gltf2')
