!pip install mapillary

mly.interface.set_access_token('MLY|')
response = mly.interface.image_from_key(id,fields = ['sfm_cluster'])
sfm_cluster_url =

I want to get the point of cloud of each image so I can reconstruction the camera position and get better visualization, positioning, however. When I try to get the url that links to sfm_cluster, it returns to me a binary stream. After that , I write it content into a txt file,
but it becomes messy code. Is there any way to decode the messy code or api that I can get the *.ply format file?
Thank you!

Additional context

Inizia dalla chiamata mly.interface.image_from_key e dal campo sfm_cluster mostrati nell’issue. Verifica come viene rappresentato il flusso binario restituito e se l’SDK o la Mapillary API documentano una risposta point-cloud o .ply. Il lavoro sarà considerato completato quando esisterà un modo documentato e utilizzabile per recuperare o decodificare i dati point-cloud.
