I'm using Repl.it and Python to communicate with an executable (stockfish, a chess engine).
i.e.:
Send a command to the stockfish executable
Get the output
This is what I'm currently doing:
stockfish = subprocess.check_output(f'printf "position fen {board.fen()}\ngo depth 7\nucinewgame\n" | ./stockfish'
, shell=True, text=True, timeout=5)
# then do something with stockfish
Weirdly, this does not work even though I have ensured that the executable works correctly. In fact, it works properly when I execute it in the shell. However, when I execute it from the Python script, it instead gives me this error:
./stockfish: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.33' not found (required by /nix/store/dd8swlwhpdhn6bv219562vyxhi8278hs-gcc-10.3.0-lib/lib/libstdc++.so.6)
Is there any way to solve this error? I have tried many alternatives, including using subprocess.run(), etc. I know that the error reports something about GLIBC being outdated, but there is nothing I can do to fix GLIBC right now, and I believe it is not necessary for the executable to be run. I am merely looking for a bypass. Thanks in advance!

I have a CodeDeploy which deploys application on Windows instances. I have a Python script which is running as part of ValidateService hooks. Below is the code I have in that script:
print("hello")
So, I have removed everything and just printing hello as part of this script. When this script is called by CodeDeploy I get below error:
My appspec.yml file:
...
ValidateService:
- location: scripts/verify_deployment.py
timeout: 900
I tried getting some help on Google but got nothing. Can someone please help me here.
Thanks
As Marcin already answered in a comment, I don't think you can simply run python scripts in CodeDeploy. At least not natively.
The error you see means that Windows does not know how to execute the script you have provided. AFAIK Windows can't run python natively (like most linux distros can).
I am not very accustomed to CodeDeploy, but given the example at https://github.com/aws-samples/aws-codedeploy-samples/tree/master/applications/SampleApp_Windows, I think you have to install python first.
After so much of investigations, I found my answer. The issue is little misleading, there is nothing to do with Code format or ENOEXEC. The issue was due to Python path. While executing my script, CodeDeploy was unable to find Python (Though I had already added python.exe in Environment variable path).
Also, I found that CodeDeploy is unable to execute .py file due to Python path issue. So, I created a PowerShell script and invoking Python script from there. Like below:
C:\Users\<username>\AppData\Local\Programs\Python\Python37-32\python.exe C:\Users\<username>\Documents\verify_deployment.py
It executed Python script successfully and gave me below output:
hello
I am trying to compile a .tex file in a Python script using pdflatex. The command pdflatex filename.tex works when I run it from the command line on Windows. However, attempting to run os.system("pdflatex filename.tex") just spits out 1 into the Python console and does not compile a pdf. I've also tried putting in the full file path similar to this person solved their problem but the same thing happens. Similarly, subprocess.call(['pdflatex', 'filename.tex']) just outputs a 1 and does not do anything.
It seems someone else has encountered the same problem in this thread, but on Mac instead of Windows. (But regardless of the operating system, they didn't find an answer.)
Why might this be happening?
EDIT: I've just discovered a solution. The script runs successfully (using the os.system approach) when I run the .py file using the command line. Previously I was attempting to run the script from RStudio, both using reticulate::source_python(filename) and also line-by-line via the reticulate REPL. Seems like the problem may actually be coming from R's reticulate package rather than anything to do with Python.
Fortunately RStudio has a terminal window so this doesn't end up being too inconvenient!
I'm getting an interesting problem and I can't determine whether it's a problem with my code or the executable that I'm running. Basically I have a Python program that needs to call an external executable to process some data. If I call the executable via PowerShell or cmd, it works fine. However, if I attempt to run the executable via os.system() or subprocess.run(), I get the following error:
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
From my understanding of googling the issue, it would appear that this is some sort of C++-related issue, which is the language of the .exe that I'm running. I reinstalled the latest Visual C++ Redist and that did not seem to affect the problem. I've also tried to create a .bat and .ps1 script that runs the .exe. These both run fine via PowerShell and CMD, but raise the same error when run via os.system() and subprocess.run(). The error message is rather nondescript so I'm wondering if anyone knows anything about it and why os.system() etc. might be throwing it.
The relevant code is simply
os.system("GaussBin.exe gaussInput.txt gaussOutput.txt")
When the string is pasted into cmd, it runs perfectly. Additionally, if the parameters of the system() call are incorrect, the exe properly displays the usage function. It's only when I add the output.txt and the program is supposed to run fully that things start to break.
I've had some confusion about what directory os.system runs in. Should I be using .\ when calling the exe?
The .exe file is provided, not built by me.
I am right now in the same directory in which the file "lookup.csv" is residing.
I have tried following commands in Python 2.7:
import subprocess
subprocess.Popen("lookup.csv", shell = True)
The above is producing the following error:
lookup.csv : not found
I have double-checked for the working directory, tried lot of available troubleshooting options given in StakExchange, tried the same in Windows (and surprisingly it was working there), what more can I do?
There's no reason why this should work on Windows because lookup.csv clearly is a file which you want to open with open whereas subprocess.Popen creates a new process for working with the lookup.csv binary. Maybe Windows handles process failure differently.
I normally program in Java, but started learning Python for a course I'm taking.
I couldn't really start the first exercise because the command
python count_freqs.py gene.train > gene.counts
didn't work, I keep getting "incorrect syntax" messages. I tried solving this looking at dozens of forums but nothing works, and I'm going crazy.
import count_freqs
ran without errors, but I can't do anything with it. When I try running something involving the file gene.train I get "gene is not defined".
Can anyone tell me what I'm doing wrong? Thanks.
type which python at the command prompt to see if the python executable is in your path. If not it either isn't installed or you need to amend your path to include it.
on Windows you can type echo %%PATH%% at the command prompt. It will give you at list of all the directories the shell search for programs to run. By default Python 3.3 will be installed on C:\Python33.
