Screenshot I am trying to write a script that runs a .exe file using a silent installer with python. My main problem is that when the installer finishes it request a user input - see screenshot attached and the script will not finish until the user hit any key to start the services
Therefore, I wrote a script that has two functions running asynchronous
As expected I am having errors
My expectations: Function click_window will wait for function run_installer to finish and then it will click enter in the cmd.exe window - I will add a screenshot
What is happening: The Script runs as expected but when it gets to os.system = (file + '/SILENT') base on the debugger - it dies out with an error message

# Tell Pyautogui what the windows name is.

Expected Results:
Function run installer finish and the window opens up to start up the services and then the click_window function starts up and clicks on the window and after 4 clicks for every service the script finish
Actual Results:
Function run installer runs but it dies at os.system = (file + '/SILENT') because the installer never installs and then it throws the following error message:

I'm currently working on a script for my sensor on my Raspberry Pi. The code underneath should get the values of my sensor and write it into a the data.json file. My problem is, if I run the scipt with my the Thonny editor everything works but if I add the script to my crontab menu the data does not get written to the data.json file.

Crontab Menu:
The line in the center is the script.
Investigation areas:
Do not put & in crontab, it serves no purpose.
You should capture the output of your scripts to see what is going on. You do this by adding >/tmp/stats.out 2>/tmp/stats.err (and similar for the other 2 lines). You will see what output and errors your scripts encounter.
cron does not run your scripts in the same environment, and from the same directory you are running them. Load what you require in the script.
cron might not have permissions to write into data.yml in the directory it is running from. Specify a full path, and ensure cron can write in that directory.
Look at https://unix.stackexchange.com/questions/109804/crontabs-reboot-only-works-for-root for usage of #reboot. Things that should occur at startup should be configured through systemd or init.d (I do not know what Rasperry Pie uses vs distro). Cron is to schedule jobs, not run things at startup.
It could be as simple as not having python3 in the PATH configured in cron.
I am trying to refresh power b.i. more frequently than current capability of gateway schedule refresh.
I found this:
https://github.com/dubravcik/pbixrefresher-python
Installed and verified I have all required packages installed to run.
Right now it works fine until the end - where after it refreshes a Save function seems to execute correctly - but the report does not save - and when it tries Publish function - a prompt is created asking if user would like to save and there is a timeout.
I have tried increasing the time-out argument and adding more wait time in the routine (along with a couple of other suggested ideas from the github issues thread).
Below is what cmd looks like along with the error - I also added the Main routine of the pbixrefresher file in case there is a different way to save (hotkeys) or something worth trying. I tried this both as my user and admin in CMD - but wasn't sure if it's possible a permissions setting could block the report from saving. Thank you for reading any help is greatly appreciated.

Had the same issue, but using "win.type_keys("^S")" solved.
I think I finally figured out what was happening. My prior post about version compatibility did not solve the issue.
It's a very strange bug - pywinauto sometimes misses the correct button. I was able to reproduce this multiple times, although it didn't happen every time - it sometimes happened on win.Refresh.click_input(), sometimes on win.Publish.click_input() This was why the popup dialog 'KoPublishToGroupDialog' cannot be found after clicking Publish and the script fails. This also indicates that the Refresh wouldn't work consistently because the script doesn't check if the dialog opens - it just waits for a predetermined amount of time to allow the refresh to finish.
I implemented a check to see if the dialog window actually opened, e.g.
if not win.child_window(auto_id="KoPublishToGroupDialog").exists():
raise AttributeError("publish dialog failed to open")
along with a retry and maximum wait loop but this didn't fix the issue. What finally worked was much simpler:
The toolbar of the PowerBI Desktop application has two modes, expanded and small. The default setup is to use expanded mode - you can minimize the toolbar to use small icons with the small arrow in the top right of PowerBI Desktop (bottom right in the pic below).
BEFORE:
AFTER
This seems to take care of the pywinauto bug (or whatever actually causes it) where the Refresh or Publish buttons are missed when clicking them.
Hope this helps someone, it took way too long to figure this out.
---UPDATE---:
Unfortunately this was NOT the full solution, what I didn't realize (and probably had a lot to do with missing the buttons) was the virtual machine's screen resolution I'm using to run this script was resized when the connection was closed. I'm using the tscon.exe solution to connect the desktop session to the console via a batch script so it isn't shut down after disconnecting. To keep the resolution I installed qres.exe (added to PATH) and added it to the batch script:
for /f "skip=1 tokens=3" %%s in ('query user %USERNAME%') do (
%windir%\System32\tscon.exe %%s /dest:console
timeout 5
qres /X 1920 /Y 1080 /C 32
)
I use this script to disconnect from the remote desktop session but keep the screen resolution. I also set up my RDP client to connect using this resolution.
At the moment I'm still not 100% sure what else might be necessary to get this to work consistently. For example after setting up the new fixed resolution I had to open PowerBI Desktop manually and set it to windowed (non-maximized) mode so it wouldn't completely miss the Refresh button (it was at least close before). My last test (staying connected) worked, disconnected from RDP it still seems to have issues though.
The program was working fine a few days ago, and it just stopped today. Not a single letter has been changed. One of my troubleshooting steps was to remove the file 'output1.mp3' and check if it will work that way, but it didn't. Another thing is that when it wasn't printing out the error, it would continue to play just this one sound file, whether or not it said the correct thing. Here's the latest error I got:

The speech synthesizer is Amazon Polly. By the way, I was using PyCharm as an IDE and working on Windows 10. When I switch to my Linux machine the speech recognition part breaks.
UPDATE: I was tweaking the code a bit and managed to fix the pyaudio error, but I got another one in the process, this time it was about permissions. Here's the error log:
Traceback (most recent call last):

with open('output11.mp3', 'wb') as f:
PermissionError: [Errno 13] Permission denied: 'output11.mp3'
UPDATE 2: I have been tikering about and I've found that the issue is only present on my Windows 10 machine, the program works fine on Linux.
Try using the absolute path (complete path) of the audio file instead of the relative path.
For example: "C:/Users/Adam/Desktop/dolphin.wav" instead of just "dolphin.wav"
This worked for me.
playsound libs has a windows directories in them.
If this fail only on Linux you should install playsound lib on the linux machine and then copy only the main3.py to it.
Answer for UPDATE2:
Copy output11.mp3 to another location and change the path to the new location:
with open('CHANGE-THIS-PATH', 'wb') as f:
Also make sure python run as administrator.
I solved this problem by moving the .py and .wav files to a folder less deep inside the file system.
I just renamed the audio file from sample.wav to sample
and then run it as playsound('sample.wav')
Luckily It ran.
Then I came to know that previously it was stored as sample.wav.wav.
So let's keep your audio file name as output.wav and try running your audio file as:
playsound('output.wav.wav') # or else rename it to output and run as
playsound('output.wav') # likewise for other audio formats too
Alright, I've found something. Not sure how to tackle it. I've seen that this is a common error that comes up in google. The error seems to have something to do with the environment variables or something. Not sure how to handle this:

that's basically it. It works fine using 'sudo python script.py' as long as the Adafruit_DHT program is in the same directory.
Here's the error I get:
Traceback (most recent call last):

I've tried adding the full path of the c program (Adafruit_DHT), to no avail...
Locate the problem.
Does the script run at all?
Do something trivial in the first line of the script to see that it actually gets executed from cron (e.g.: write to a file in /tmp).
Once you managed to run it, look for other problems. Cron can be set up to send the a mail with the output of the script. One obvious thing I see is: ./Adafruit_DHT, relative path is used, that's a bad sign, the cron script is probably not executed in the directory you think it does. Fix it (= use absolute path).
Try:
output = subprocess.check_output(["PATH_TO_Adafruit_DHT/Adafruit_DHT", "2302", "17"]);
Oh and change your cron line to:
/usr/bin/python /home/pi/myscript.py
I am trying to run a python file from the command line with a single parameter in Ubuntu 12.04. The program works if I simply run it from the IDE and pass the parameter in the code. However, if I call 'python readFromSerial1.py 3' in the command prompt, I get:
Traceback (most recent call last):
File "readFromSerial1.py", line 62, in <module>
main()
File "readFromSerial1.py", line 6, in main
readDataFromUSB(time)
File "readFromSerial1.py", line 9, in readDataFromUSB
import usb.core
ImportError: No module named usb.core
I'm a little confused as the module imports correctly if I run from the IDE. I download the pyUSB module and extracted it (its filename is pyusb-1.0.0a3). I then copied this file into
/usr/local/lib/python2.7/site-packages/. Is that the correct procedure? I have a feeling the issue is due to python simply not being able to find the usb module and I need to put it in the correct location. My code is below, and any help would be greatly appreciated:
readFromSerial1.py
import sys
def main():
time = sys.argv[1]
#time = 1
readDataFromUSB(time)
def readDataFromUSB(time):
import usb.core
#find device
dev = usb.core.find(idVendor=0x099e, idProduct=0x0001) #GPS info
#Was the device found?
if dev is None:
raise ValueError('Device not found')
else:
print "Device found!"
#Do this to avoid 'Errno16: Resource is busy'
if dev.is_kernel_driver_active(0):
try:
dev.detach_kernel_driver(0)
except usb.core.USBError as e:
sys.exit("Could not detach kernel driver: %s" % str(e))
#Sets default config
dev.set_configuration()
#Gets default endpoint
endpoint = dev[0][(0,0)][0]
writeObject = open("InputData.txt", "w")
#iterate for time purposes
for i in range(0, (time*6)): #sys.argv is command line variable for time input
data = dev.read(endpoint.bEndpointAddress, endpoint.wMaxPacketSize, 0, 100000)
sret = ''.join([chr(x) for x in data])
writeObject.write(sret);
print sret
'''
newStr = ''.join(sret[7:14])
compareStr = ",*4F"
if (newStr == compareStr):
print "The GPS is not reading in any values right now. Try going somewhere else with better reception."
else:
print sret[7:14]
'''
writeObject.close()
main()
