MPI/python application trace

I have an MPI python application and I tried to trace it using intel trace analyzer and collector. I am running my application on a HPC, I tried to get the .stf trace files to be used as input to intel trace analyzer using this link: https://www.intel.com/content/www/us/en/develop/documentation/get-started-with-itac/top/trace-your-mpi-application.html and this command on linux; mpiexec -trace -n 2 python3 ./run.py,
but I am getting the following error:
Error: mpiexec: Error: unknown option "-trace"
When I run only mpiexec -n 2 python3 ./run.py, it works, but when I added the trace option, it doesn't work, ..
Thank you in advance.

Heroku local command not working: /bin/sh: python: command not found

I am trying to use heroku local to run my heroku application but whenever I run heroku local, I get the following error:
$heroku local
9:58:47 AM web.1 | /bin/sh: python: command not found
[DONE] Killing all processes with signal SIGINT
9:58:47 AM web.1 Exited with exit code null
I am wondering if the issue is that I have python3 installed and not python, because when I run which python3 I get:
/Library/Frameworks/Python.framework/Versions/3.8/bin/python3
However, when I run which python I get nothing.

The problem is that you don’t have a command named python on your system. Change your Procfile to python3 instead.

Patchman Error during install ModuleNot Found Error: 'importlib.metadata' --python3-patchman

I have attached the image of the error dpkg error
I'm not really a developer so I am not sure how to troubleshoot something like this really? what direction should I be going?
I've looked around for ways to install any missing dependencies but now its unable to connect to "patchman server" which I don't believe has even been defined yet with a host/ip

How to keep app from crashing while using the subprocess in Python

Greetings to the stackoverflow community. I need some direction in how to keep my Python cmd line app from crashing when the network I'm cloning a repository from (GitHub) disconnects because many clone requests. Below is the code that I use to clone the repo. Currently, it runs fine. But, I imagine, when there are multiple people downloading the repo or something is slow about the network, I get kicked off, and my app crashes. I thought the try/except statement would prevent crashing, but to no avail:
...
command = r'git clone git#github.com:somerepo.git'
try:
subprocess.call(command, shell=False)
except subprocess.CalledProcessError as cpe:
click.echo(cpe.output)
...
Error:
Git Clone Fails - error: RPC failed; result=56, HTTP code = 200
git clone http://somerepo/repo.git
fatal: early EOF
fatal: The remote end hung up unexpectedly
fatal: index-pack failed
error: RPC failed; result=56, HTTP code = 200
