Hello. I am attempting to do very basic things, such as output a TLL signal, output an RF signal, or turn on an LED and am having difficulties. I know the dashboard is connected to the system, as I can manually override the signals through the dashboard and that works. However when I try to run a basic experiment such as
`from artiq.experiment import *
class LED(EnvExperiment):
def build(self):
self.setattr_device("core")
self.setattr_device("led")
@kernel
def run(self):
self.core.reset()
self.led.on()`
which was taken from the manual, nothing happens (same with the other examples from the [manual](https://m-labs.hk/artiq/manual/getting_started_core.html)). I can see through the schedule on the GUI that the experiments get hung running. If I add a print statement in the run method, I do not see any prints in the log or the terminal where I ran artiq_session, which makes me believe that it is hanging before the run method. Any solutions/suggestions/advice would be greatly appreciated. Thanks!
