`GetSceneGraphOfImage` function call hangs

ebigelow commented 8 years ago

I have been unable to use the GetSceneGraphOfImage function in the API recently. When I used it about a month ago, it would be extremely slow - from 1 to 10 minutes to load a single scene graph. As of last night, I have been unable to acquire any scene graphs. Once I call the function, it seems to hang infinitely (for at least 10-12 hours).

If I interrupt the process while it's hanging, I get the following trace:

I solved this problem by using:

import ssl
ssl._create_default_https_context = ssl._create_unverified_context

ebigelow commented 7 years ago

@wang-tf Ah, this works for me. It took some extra time the first call I made to the API, but since that first call went through, I've been able to download other scene graphs fairly quickly.
