I have a python script in a batch file with the following code. This runs fine when I double click the .bat file to run it. However, when I run it through Task Scheduler it gives a 0x1 run error. I've tried experimenting and it seems removing the >log.txt 2>&1 allows it to run from task scheduler. I added this line to log any exceptions and print statements to a txt file. Does anyone know why it causes an error with task scheduler but not when the batch file is manually executed?
python "C:\Users\XXX\untitled0.py" >log.txt 2>&1
A scheduled task runs with a working folder of (usually) C:\Windwos\System32, which is write protected.
Give the full path: ... > "%userprofile%\xxx\log.txt 2>&1
or do a cd /d "%~dp0 before to switch to the folder where your script is located.
0x1 run error is cause by privilege error. In your case, the issue is probabily the fact the Task Scheduler lacks the privilege to write the log.txt file infact, as you have described, running the script with no >log.txt 2>&1 has no issue.
Move the script to "C:\untitled0.py" and run it with the Task Scheduler from there
My question seems to be quite easy, but for some reason I did not find a quick answer to it. I have a python script that I want to run on the terminal command line (Ubuntu linux server), which works for me. But then I can't use the command line until the script ends. The script takes a long time to run, and I would like to continue using the command line to perform other tasks. How can you do the work of a script when its progress is not shown on the command line, but keep its work? And how can I see the active processes that are running on the server to see if a process is running?
Run script command:
python script.py
Add next with & echo "123":
The script takes a long time to run, and I would like to continue
using the command line to perform other tasks.
It seems that you want to run said process in background, please try pasting following
python script.py &
echo "123"
it should start your script.py and then output 123 (without waiting until script.py ends)
how can I see the active processes that are running on the server to
see if a process is running?
Using ps command
ps -ef
will list all processes which you would probably want to filter to get interested one to you.
Say I am running a nohup job with a python file:
nohup python -u train_model.py 2>&1&
If I make a change to the python file and save it, will the nohup job be affected?
Once you run the python program, regardless of using nohup or not, it will be loaded into memory and will not be altered when you change the source code which resides in your disk.
Changes will apply only if you re-run it after the initial process complete, or if you run it in parallel.
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.

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
I have a Python3 script that can take optional command line parameters which the script reads via sys.argv. My script works fine if I run it from a terminal window, however any time I add it to the PA schedule tab with parameters, I get a bash 126 exit code in the log. According to the bash appendix this exit code means Permission problem or command is not an executable. So, it would appear that the scripts running from a terminal window don't run in the same context as scripts run from schedule, because my script runs fine from a bash terminal.
What I need is to figure out a way to get scripts to run with optional command line parameters via the schedule tab.
I figure I could write another script that calls the first script with the optional parameters, however it seems to me there should be another way to get around this where you can just put the parameters you wish to run the script with directly on the line you give to the schedule tab to run. Otherwise I'll have to write a script for each separate set of parameters I want to call with versus just an entry to schedule the script to run.
Thanks to #Lattyware for this solution. If you have this problem you can solve it by going to a terminal and adding the execute bit on your script. You can accomplish adding the execute permission using chmod such as:
chmod 700 foo.py
You may also want to verify your file permissions prior to any changes to ensure you don't add or remove something you didn't intend to.
You can read up on chmod here if you need to.
