Hi, Very happy to receive your reply.I ran the algorithm in version 2.8 and there was no error, so I think it may be that I did not properly configure the environment required for version 3.0, of course, it may also be a problem that you pointed out above. Sorry for not giving you feedback in time whether my problem is solved.
Thank you again for your reply.And thanks for your tutorial, it helps me a lot.Look forward to seeing your update again in the tutorial.
Best wishes.
