Having trouble with Windows Task Scheduler, and didn't find a solution browsing through other questions. We've got several Python Scripts running via Task Scheduler that are all running just fine, but there's one in particular that just won't run.
The "Run whether use is logged in or not" box is checked, as well as the "Run with highest privileges" box, as it is with the ones that are working.
In the Start Program box I have "C:\Program Files\Python310\python.exe" and in the Add Arguments box I have C:\Users\<user>\<dir1>\<dir2>\script.py.
Using cmd, the following runs the program and generates the file I want perfectly, which is just the exact same things as above.
"C:\Program Files\Python310\python.exe" C:\Users\<user>\<dir1>\<dir2>\script.py
I've tried changing the location of the python interpreter, using a different interpreter version, using task scheduler to run CMD first with the above as arguments, and nothing seems to do it.
On every attempt, I get the following:
Task Started (1)
Action started (1)
Action completed (2)
Task completed (2)
And every time this happens, the script hasn't actually run. I even copy/pasted my the bits in task scheduler into CMD to make sure I didn't overlook a typo or something like that.
Thanks in advance!

I have a windows server 2012, where I need to move some .hash file from one directory to another one.
I build a simple python script that runs well when I launch it manually, the files are all moved.
Now I need to schedule windows for run it every 5 minutes. Task scheduler schedule it, and every 5 minutes execute it, but simply the files are no more moved, even if Task Schedule says it runned successfully.
I googled a lot of similar question, trying to fill the start in field, build a .cmd script and other things like that, none of these worked.
How can I fix it?
I found out later that there was something wrong with admin's permissions.
With the correct user now all works fine.
Is there any way to run python script on Windows VM continuously. This script should run even computer restarts automatically.
What I am doing right now?
I have a script called FooBar.py, it contains infinite while loop to execute main() function continuously. I am running this script on powershell.
What is problem in this approach?
Sometime this VM restarts automatically or powershell window may close accidentally. This kind of issues causing failure of script execution.
What I have tried so far?
I tried pythonw.exe instead of python.exe to run the script but this does not resolve my problem.
Is there any way to run FooBar.py script continuously, is there any way in windows scheduler to restart script execution even after computer restarts
You can use pm2 to schedule the startup of your script. You can find more information on how to use it here:
https://towardsdatascience.com/automate-your-python-script-with-pm2-463238ea0b65
you can use a module of python named "schedule"
and possibly you can run your code at whatever time you need !
use "pip install schecule" to download the library or module.
for an example i will leave you a pic how to use it.
enter image description here
i mean job in the picture is a function what you want to do.
if you want it to do for a time interval in secdonds then,you can use
schedule.every(#duration#).seconds.do(#declared function#)
thank you!
Create a task in windows scheduler with trigger On a schedule and with trigger option Repeat task every 1 min. Then in a Settings tab there is the dropdown menu If the task is already running, then the following rule applies: where you can choose Do not start a new instance.
I am trying to set up a python code to be executed automatically.
I started with a small code to be executed:
import datetime
with open("out.txt","a") as f:
f.write(datetime.datetime.now().isoformat())
The task will start allright, and executes (The file is modified), but it never ends in the task scheduler.
this and this exist in SO, but have no real answer. The only workaround proposed in these threads is to force the end of task after a given time in Windows, but this requires to know how long the python script will take which will not be the case for my actual task.
How can the task scheduler know that a python script is finished ?
I run it the following way in the task scheduler :
program : cmd
arguments : /c C:\python27\python.exe C:\path\of\script.py
execute in : C:\path\of\
I tried some variations around this, like executing python instead of cmd, but it didn't change anything. I had hoped the /c would force the task to close.
as Gaurav Pundir mentioned, adding sys.exit(0) should end the script properly and thus the task. However, you do need to add the sys library with import sys in order to use sys.exit(0). Hope this helps!
it looks like a bug to me.
Try looking up for python console under Task Manager.
if it is not there then the program has exited successfully.
I have the same issue with Windows 10, python script ran successfully, there is no python console under Task Manager, yet the scheduled task Status still says 'Running'
There seems to be no correct fix for such issue with CMD as the intermediate launcher.
There is a [End] command in Task Scheduler GUI, clicking it will always terminate the CMD/batch file leaving the spawned python.exe process to straw.
The real problem: there doesn't seem to be any way for cmd to pass on the terminate signal to python.exe.. and neither can taskengine reliably determine if python.exe is alive or not.
I ran into the same problem, the python file didn't stop in the task scheduler. I imported sys and wrote sys.exit(0) but I still got the same problem.
Finally, I decided to press "Update" which solved my problem; the status of the task was "Ready", and not "Running". For information, I use windows 11.
So I have a python script that is copying a bunch of files between folders. This script runs exactly as intended until I try to use the task scheduler to get it to run at regular intervals. I have run it several different ways and it always runs fine, but when I create a scheduled task it gives me an error (it says it can't find a folder that I have confirmed exists). I've tried creating a batch file to launch the python script through the task scheduler and it doesn't work, even though it works when I run the batch file manually. I've also tried calling python through the scheduled task with the python script as an argument through the scheduler and it doesn't work. Running manually through python also works, double clicking the python script work. It's only through the scheduler that I can't get it to run. Suffice to say it is quite frustrating. Any ideas?
When creating the task using Task Scheduler, make sure you give full PATHs to everything, for example:
Program/script: C:\Python27\python.exe
Add arguments (optional): -u "C:\Users\MyUserName\Documents\MyScript.py"
Start in (optional): C:\Users\MyUserName\Documents
Secondly, you could also force the working folder from within your script:
import os
os.chdir(os.path.dirname(os.path.abspath(__file__)))
Not sure if anyone has run into this, but I'll take suggestions for troubleshooting and/or alternative methods.
I have a Windows 2008 server on which I am running several scheduled tasks. One of those tasks is a python script that uses pscp to log into a linux box, checks for new files and if there is anything new, copies them down to a local directory on the C: drive. I've put some logging into the script at key points as well and I'm using logging.basicConfig(level=DEBUG).
I built the command using a variable, command = 'pscp -pw xxxx name#ip:/ c:\local_dir' and then I use subprocess.call(command) to execute the command.
Now here's the weird part. If I run the script manually from the command line, it works fine. New files are downloaded and processed. However, if the Task Scheduler runs the script, no new files are downloaded. The script is running under the same user, but yet yields different results.
According to the log files created by the script and on the linux box, the script successfully logs into the linux box. However, no files are downloaded despite there being new files. Again, when I run it via the command line, files are downloaded.
Any ideas? suggestions, alternative methods?
Thanks.
You can use the windows Task Scheduler, but make sure the "optional" field "Start In" is filled in.
In the Task Scheduler app, add an action that specifies your python file to run "doSomeWork" and fill in the Start in (optional) input with the directory that contains the file.. So for example if you have a python file in:
C:\pythonProject\doSomeWork.py
You would enter:
Program/Script: doSomeWork.py
Start in (optional): C:\pythonProject
I had the same issue when trying to open an MS Access database on a Linux VM. Running the script at the Windows 7 command prompt worked but running it in Task Scheduler didn't. With Task Scheduler it would find the database and verify it existed but wouldn't return the tables within it.
The solution was to have Task Scheduler run cmd as the Program/Script with the arguments /c python C:\path\to\script.py (under Add arguments (optional)).
I can't tell you why this works but it solved my problem.
I'm having a similar issue. In testing I found that any type of call with subprocess stops the python script when run in task scheduler but works fine when run on the command line.
import subprocess
print('Start')
test = subprocess.check_output(["dir"], shell=True)
print('First call finished')
When run on command line this outputs:
Start
First call finished
When run from task scheduler the output is:
Start
In order to get the output from task scheduler I run the python script from a batch file as follows:
python test.py >> log.txt
I run the script through the batch file both on command line and through task scheduler.
Brad's answer is right. Subprocess needs the shell context to work and the task manager can launch python without that. Another way to do it is to make a batch file that is launched by the task scheduler that calls python c:\path\to\script.py etc. The only difference to this is that if you run into a script that has a call to os.getcwd() you will always get the root where the script is but you get something else when you make the call to cmd from task scheduler.
Last edit - start
After experiments... If you put there full path to python program it works without highest privileges (as admin). Meaning task settings like this:
program: "C:\Program Files\Python37\python.exe"
arguments: "D:\folder\folder\python script.py"
I have no idea why, but it works even if script uses subprocess and multiple threads.
Last edit - end
What I did is I changed task settings: checked Run with highest privileges. And task started to work perfectly while running python [script path].
But keep in mind, that title contains "Administrator: " at the begining... always...
P.S. Thanks guys for pointing out that subprocess is a problem. It made me think of task settings.
I had similar problem when one script is running from Windows Task Scheduler, and another one doesn't.
Running cmd with python [script path] didn't work for me on Windows 8.1 Embedded x64. Not sure why. Probably because of necessity to have spaces in path and issue with quotes.
Hope my answer helps someone. ;)
Create a batch file add your python script in your batch file and then schedule that batch file .it will work .
Example : suppose your python script is in folder c:\abhishek\script\merun.py
first you have to go to directory by cd command .so your batch file would be like :
cd c:\abhishek\script
python merun.py
it work for me .
Just leaving this for posterity: A similar issue I faced was resolved by using the UNC (\10.x.xx.xx\Folder\xxx)path everywhere in my .bat and .py scripts instead of the letter assigned to the drive (\K:\Folder\xxx).
I had this issue before. I was able to run the task manually in Windows Task Scheduler, but not automatically. I remembered that there was a change in the time made by another user, maybe this change made the task scheduler to error out. I am not sure. Therefore, I created another task with a different name, for the same script, and the script worked automatically. Try to create a test task running the same script. Hopefully that works!
For Anaconda installation of python in windows below solution worked for me
create a batch file with below
"C:\Users\username\Anaconda3\condabin\activate" && python "script.py" &&
deactivate
Setup task to run this batch file
