With a button connected to GND and PIN_D on a V2 AIY Voice Bonnet and code:
from gpiozero import Button
from signal import pause
from aiy.pins import PIN_D
button = Button(PIN_D)
button.wait_for_press()
print("The button was pressed.")
pause()
I get messages:

On release 8.1.1 I am trying to experiment with the simple web agent.
Running through the setup process
volttron -vv -l volttron.log --bind-web-address http://0.0.0.0:8080 &
Everything seem to install OK for http protrocol on the vcfg and starting the agent starts fine but going to the browser I get an empty page response.
And in terminal an error here's the Full traceback:

EDIT
So if I do a nano ~/.volttron/config it looks like this below. I did change the bind-web-address for the IP address of my test bench instance. Hopefully that wasn't a mistake it looked like the initial bind-web-address was the name of the computer. --bind-web-address http://ben-hp-probook-6550b:8080
message-bus = zmq
vip-address = tcp://127.0.0.1:22916
instance-name = benshome
bind-web-address = http://192.168.0.105:8080
web-ssl-cert = /home/ben/.volttron/certificates/certs/platform_web-server.crt
web-ssl-key = /home/ben/.volttron/certificates/private/platform_web-server.pem
web-secret-key = 0e3b19770c0a8c0a08f274fcdabaf939fecc16601283266934c5ab258a1ed20cf440fde2c83cb8660dac569d31b5cdaf3ab7354a39b0640f355f9c5407c5fce619
I think I did first try HTTPS then resorted to HTTP. Anyways when I start VOLTTRON do I still need a --bind-web-address arg if the ~/.volttron/config is already setup with one?
I've a tried both when starting VOLTTRON to use the --bind flag or not but still unable to bring up a webpage on the IP address of the machine running VOLTTRON of 192.168.0.105. This would be the simple web agent, right?
I was able to reproduce this when I ran through vcfg and specified https, but then did what you did and passed the bind-web-address to the volttron command itself.
However, you shouldn't do this. The instructions assume you haven't gone through the vcfg process and therefore you would have to specify the bind web address on the command line.
Since you went through the vcfg process your config file (~/.volttron/config) will have your hostname:port as the bind-web-address. If it has https in it that is the reason it is not working for you.
I created a training script with hard coded input. It works as expected using a training job but I couldn't make it work using local mode.
It brings up a container on my local docker and exits with code (1)
Code:
estimator = SKLearn(entry_point="train_model.py",
train_instance_type="local")
estimator.fit()
Here is the exception:

I found out that docker restart solved the issue.
After a while it happened again - and it solved it again.
I'm using docker for windows, and the issue is probably related to the created container configuration
I'm trying to run a meta-analysis on a database of fMRI data, using the neurosynth python library through idle. When I try to run even some of the most basic functions, I get an error, not an error my own code, or in the neurosynth modules, the error seems to be a bug in idle itself.
I uninstalled and reinstalled python 2.7, reinstalled neurosynth and its dependencies, and ran into the same error. I've pasted my code below, followed by the error message, which appears in the unix shell (not in the idle shell).
Has anybody come across this error before using idle and python 2.7?
The script:
from neurosynth.base.dataset import Dataset
from neurosynth.analysis import meta, decode, network
import neurosynth
neurosynth.set_logging_level('info')
dataset = Dataset('data/database.txt')
dataset.add_features('data/features.txt')
dataset.save('dataset.pkl')
print 'done'
The error message which appeared in the unix shell:

Idle is meant for interactive exploration in the shell, for editing in an editor, and for testing programs by running them from an editor. It is not meant for production running of programs once developed. If there is a problem, one should separate the Idle part from the running with Python part. So in the unix shell, run python -m idlelib (for instance) to see if Idle starts correctly. Then, in an appropriate directory, run python path-to-my-file.py. Which does not work?
The error message is definitely odd, as it has more than just the python traceback. On the other hand, it does not start with a line of your code. I have no idea why the select call would be interrupted.

I've run into a weird problem with a script that uses selenium.webdriver.PhantomJS.
SYMPTOMS…
My script uses the following to start a phantomjs session
from selenium import selenium
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.action_chains import ActionChains
(…)
def load_driver(self, _driver = "phantomjs", _path = "./phantomjs"):
if "phantom" in str(_driver).lower():
self.driver = webdriver.PhantomJS(_path)
Fails with:
selenium.common.exceptions.WebDriverException: Message: 'Unable to start phantomjs with ghostdriver.' ; Screenshot: available via screen
HOWEVER, at the python command line, everything works fine…
from selenium import webdriver
_path = './phantomjs.exe'
driver = webdriver.PhantomJS(_path)
PLATFORM: Linux
platform.system() != 'Windows': True
(I’ll explain “PLATFORM: Linux”, and “platform.system() != 'Windows': True” below)
SO…
I traced the error to the “/usr/lib/python2.6/site-packages/selenium/webdriver/phantomjs/service.py” and specifically this code…
def start(self):
"""
"""
try:
print "PLATFORM:", platform.system() #ADDED BY ME
# FOLLOWING ADDED BY ME, NOW CAUSING THE ERROR
print "platform.system() != 'Windows': ", platform.system() != 'Windows'
self.process = subprocess.Popen(self.service_args, stdin=subprocess.PIPE,
close_fds=platform.system() != 'Windows', # <-- THIS CAUSED ORIG PROB
stdout=self._log, stderr=self._log)
except Exception as e:
raise WebDriverException("Unable to start phantomjs with ghostdriver.", e)
AND HERE’S THE ISSUE…
When I run the code at the python command line (see above) everything is fine, AND the responses to ‘platform.system()’ and “platform.system() != 'Windows' ” are correct.
However, when I run my script, the ‘platform.system()’ reports blank and “platform.system() != 'Windows' ” errors. (See actual output below).
So, for some reason, when my script loads selenium and runs…THE SELENIUM CODE loses the ‘platform’ import.
Thanks for the help!
ACTUAL OUTPUT BELOW (NOTICE that 'PLATFORM:' is followed by 'blank' (instead of 'Linux'), and the next line “platform.system() != 'Windows' ” triggers the error. These lines were added by me into the SELENIUM code, not my code!)

The problem is with the single quotes being used for the arguments 'http://www.amazon.com/cloudplayer'
Just using - http://www.amazon.com/cloudplayer worked fine. RobotFramework by defaults takes the arguments as raw strings
