[MSNoise] failed to run 01.scan_archive_threaded.py

[Wang, Xiao]

Hi Thomas,

I try script python s01scan_archive.py init 4, but I still get same exception. I check database and tables of jobs, filters and data_availability are empty.

Regards,

Xiao

Hello Xiao,

That is weird, could you test using more than 1 thread:

python s01scan_archive.py init 4

where 4 means 4 threads
