[IPOL discuss] question about run_algo

[Juan Cardelino]

I've created one demo and make it run succesfully, however since
yesterday I'm having some problems to run my 2nd demo. I'm getting a
file not found error, but I can' tell if the problem is to find the
executable or the log file. I have a little doubt: the path used by
the demo, contains only the bin/ subdir or the full path of the
system? I've double checked that the executable (qnm) is in place and
runs from the command line. Below is the code of the run_algo function
and the output.
Thanks.

------------- CODE -------------

 def run_algo(self, a, b):
        """
        the core algo runner
        could also be called by a batch processor
        this one needs no parameter
        """
        cherrypy.log("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX")
	cherrypy.log("START ALGO LOG")
	cherrypy.log("bin_dir: "+self.bin_dir)
	stdout_abs_filename = self.work_dir + self.stdout_rel_name
        stdout_file = open(stdout_abs_filename, 'w')
	cherrypy.log("stdout_file: "+stdout_abs_filename)	
	
	#p0 = self.run_proc(['ls','.'], stdout=stdout_file, stderr=stdout_file)
        #self.wait_proc(p0)

	p1 = self.run_proc(['qmn','main_ms_tree_vec_demo',
str(a),str(1),'input_0.png', 'output.tr', 'init_part.part'],
stdout=stdout_file, stderr=stdout_file)
        #p1 = self.run_proc(['qmn','main_ms_tree_vec_demo',
str(a),str(1),'input_0.png', 'output.tr', 'init_part.part'])   # I
ALSO TRIED THIS ONE TO REMOVE POSSIBLE PROBLEMS WITH THE FILES
        self.wait_proc(p1)

----->>>more code...but this run_proc is the one that fails.
