Running .elf file with artiq_master

Philipp

I am trying to run an experiment that was compiled with artiq_compile by using the artiq_master.
So far scheduling a phyton file has worked fine.
But with

sipyco_rpctool 127.0.0.1 3251 call -t master_schedule submit 'main' {'class_name':'Sequence','file':'test.elf','arguments':{},'log_level':10,'repo_rev':'N/A',}

I get

ARTIQ: (40, 'worker(21,test.elf)', 1653386680.6618598, 'root:Terminating with exception (AttributeError: 'NoneType' object has no attribute 'loader')
Traceback (most recent call last):
  File "C:\Anaconda3\envs\artiq\lib\site-packages\artiq\master\worker_impl.py", line 282, in main
	exp = get_experiment(experiment_file, expid["class_name"])
  File "C:\Anaconda3\envs\artiq\lib\site-packages\artiq\master\worker_impl.py", line 133, in get_experiment
	module = tools.file_import(file, prefix="artiq_worker_")
  File "C:\Anaconda3\envs\artiq\lib\site-packages\artiq\tools.py", line 82, in file_import
	module = importlib.util.module_from_spec(spec)
  File "<frozen importlib._bootstrap>", line 580, in module_from_spec
AttributeError: 'NoneType' object has no attribute 'loader'')

Is it not possible to submit an .elf file to the master_scheduler?

This is not implemented, though it wouldn't be very difficult to implement I believe.
By the way you can use artiq_client for a simpler command line.

In the artiq\master\worker_impl.py I changed this paragraph to use the ELFRunner class which is defined in artiq_run.py. It seems to work, but feels a bit hacky.

			if action == "build":
				start_time = time.time()
				rid = obj["rid"]
				expid = obj["expid"]
				if obj["wd"] is not None:
					# Using repository
					experiment_file = os.path.join(obj["wd"], expid["file"])
					repository_path = obj["wd"]
				else:
					experiment_file = expid["file"]
					repository_path = None
				setup_diagnostics(experiment_file, repository_path)
				if expid["file"].endswith(".elf"):
					exp_inst = ELFRunner((device_mgr, dataset_mgr, ProcessArgumentManager(expid["arguments"]), {}), file=expid["file"])
					exp = ELFRunner
				else:
					exp = get_experiment(experiment_file, expid["class_name"])
					device_mgr.virtual_devices["scheduler"].set_run_info(
						rid, obj["pipeline_name"], expid, obj["priority"])
					start_local_time = time.localtime(start_time)
					dirname = os.path.join("results",
									time.strftime("%Y-%m-%d", start_local_time),
									time.strftime("%H", start_local_time))
					os.makedirs(dirname, exist_ok=True)
					os.chdir(dirname)
					argument_mgr = ProcessArgumentManager(expid["arguments"])
					exp_inst = exp((device_mgr, dataset_mgr, argument_mgr, {}))
				put_completed()
