Reduce Import Time #495
Description
The time that it takes for STUMPY to get imported has been growing. This is assessed via:
$ python -X importtime -c "import stumpy"
Which shows the bulk of the import time being spent here:
...
import time: 1476386 | 1820531 | stumpy.core
import time: 1137810 | 1137810 | stumpy.aamp
import time: 2498991 | 3636800 | stumpy.stump
import time: 342 | 342 | stumpy.aamped
import time: 476 | 817 | stumpy.stumped
import time: 844657 | 844657 | stumpy.maamp
import time: 718504 | 1563161 | stumpy.mstump
import time: 351 | 351 | stumpy.maamped
import time: 472 | 823 | stumpy.mstumped
import time: 301 | 301 | stumpy.aampi
import time: 195 | 195 | stumpy.chains
import time: 205 | 205 | stumpy.floss
import time: 254 | 254 | stumpy.aamp_ostinato
import time: 291 | 544 | stumpy.ostinato
import time: 1209154 | 1209154 | stumpy.scraamp
import time: 794046 | 2003200 | stumpy.scrump
import time: 1048 | 1048 | stumpy.stumpi
import time: 160 | 160 | stumpy.aampdist
import time: 199 | 358 | stumpy.mpdist
import time: 290 | 290 | stumpy.aamp_motifs
import time: 183 | 473 | stumpy.motifs
import time: 146 | 146 | stumpy.aampdist_snippets
import time: 174 | 320 | stumpy.snippets
import time: 236 | 236 | stumpy.stimp
import time: 6004 | 9125575 | stumpy
It would be great to figure out how to reduce this import time down. It appears that it has something to do with how we are importing functions into __init__.py
