Automatically created environment for python package
Project description
Project daskcheck
Help with a simple use of the dask
The idea
- define properly the core function (xcorefunc in the example) with THE return
daskcheck
then will take care about:- sending the parameters
- collecting results and saving them to local json file
Instalation of daskcheck
pip install daskcheck
Installation of dask
See https://docs.dask.org/en/stable/install.html
pip install "dask[complete]"
Launching dask scheduler/workers
Pay attention to correct/compatible libraries on different workers
Environment needed
to be done
Launching scheduler
dask scheduler --port 8786
Launching worker
dask worker 127.0.0.1:8786 --nworkers 5 --nthreads 1
Testing dask
IN DEVELOPMENT...
This runs (sched and workers are ON) 40x getcpuinfo
./daskcheck.py test
This is solved .... possible to load (unload first). See tesmod.py
./daskcheck.py dask py_file_with_main 1,3
./daskcheck.py dask py_file_with_main 11..33
Monitoring dask
xdg-open http://localhost:8787
Recollection the data from json
Usage
from daskcheck import daskcheck
from fire import Fire
import time
import platform
import datetime as dt
import json
def main( parlist ):
parameters = daskcheck.prepare_params( parlist )
if type(parameters)==list:
print("i... viable for DASK ....")
daskcheck.submit( daskcheck.get_cpu_info , parameters)
else:
print("i... running only locally")
my_results = xcorefunc( 1 , parameters )
# Write LOG file.
now = dt.datetime.now()
stamp = now.strftime("%Y%m%d_%H%M%S")
with open(f"dask_results_log_{stamp}.json", "w") as fp:
json.dump( my_results , fp, sort_keys=True, indent='\t', separators=(',', ': '))
return
def xcorefunc( order, param):
"""
Function to be sent to dask server with order# + parameter
"""
import ROOT # I need to avoid breaking pickle
start_time = time.perf_counter()
return order, [platform.node(), f"{time.perf_counter() - start_time:.1f} s" , ni]
if __name__=="__main__":
Fire(main)
