Hi everybody,
I'm quite new to rpyc and I'm not able to solve a problem. I have a class
that it is using subprocess, if I run it from python it is working without
problem but if I try to use it with rpyc it return me an error because it
seems that subprocess it is not running properly.
My class is like this
class stemGRASS():
def __init__(self, pid, grassdatabase, location, grassbin, epsg):
startcmd = [grassbin, ' --config path']
p = subprocess.Popen(startcmd, shell=True, stdin=subprocess.PIPE,
stdout=subprocess.PIPE, stderr=subprocess.PIPE)
out, err = p.communicate()
if p.returncode != 0:
raise Exception("Error running GRASS")
I tried both classic and services method but it return the error
In [18]: %paste
import rpyc
conn = rpyc.classic.connect("localhost")
conn.modules.sys.path.append('/home/lucadelu/.qgis2/python/plugins/STEM')
gr = conn.modules.grass_stem.stemGRASS('123456', '/home/lucadelu/grassdata/'
, 'latlong', '/home/lucadelu/bin/grass70', '4326')
