Dear everyone,
I have a little question about how Python and Metashape works.
I have a problem, because I have to speed up a script which extract coordinates for any selected point in Metashape, but it needs like 27 days to run across 1 milion points.
For this reason I was wondering if you know a way to multiprocess everything and speed up a little the process.
I have already splitted my dataframe in several parts, to call it in different functions, and I tried with asyncio to see if the process was speeding up a little but nothing. So I was wandering if multiprocessing package was a good solution. Unfortunately until now it gives me always an error:
Traceback (most recent call last):

ForkingPickler(file, protocol).dump(obj)

Do you have any Idea?
Thank you in advance.
Best regards.
