The scene file of unity of procthor-10k

Procthor is built off the ai2thor controller, and when the ai2thor controller start for the first time, it would download the 3D scenes to ~/.ai2thor, and these scenes data can be loading by Unity. So when we use the scenes in procthor-10k, where are all the scenes in procthor-10k download? The scenes in ~/.ai2thor/releases/thor-Linux64-391b3fae4d4cc026f1522e5acf60953560235971 seems to be the scenes data in ai2thor not in procthor-10k
