Raspberry Pi 4 running Raspian (most current as of 02/09/2023), Python 3.9.2. Installed Pymodbus with pip3 install -U pymodbus[twisted] (detail: it said twisted was not available).
When I run my code in Python I get the error ModuleNotFoundError: No module named 'pymodbus.server.asynchronous' on the line from pymodbus.server.asynchronous import StartTcpServer, StopServer.
Any idea as why it is not working? Same process used to work in 2021 with Python 3.7.
Installed Pymodbus from this command pip3 install -U pymodbus[twisted]
EDIT: I read the official page for Pymodbus https://pypi.org/project/pymodbus/ which says that the current version of it is compatible with Python 3.8+ , and the old versions of it were compatible with up to Python 3.7 (which was the version I was using). Could this be breaking the code and giving me the error i'm getting?
EDIT 2: Full traceback

Twisted is removed from 3.0.0dev5, and I can see that you used this import line in your code:
from pymodbus.server.asynchronous import StartTcpServer, StopServer
This is an old implementation working only for 2.5.3<, there is a new way of implementing an async server - check here the example.

I just upgraded to Pop OS(Ubuntu) 20.04, which upgraded Python 3.7 to 3.8. Now I get this error below when I run sam (from the AWS SAM CLI). Solutions found online all had to do with making sure python3-distutils is installed. I have verified that python3-disutils is installed. /usr/lib/python3.8/distutils looks fine, just not getting picked up for some reason.
One thing I noticed is that in the traceback below, it's using the system-wide pip, while I have a later version of pip installed under my .local. I don't know if those two symptoms are related but looks like I'm missing some config somewhere so none of the 3.8 or user space stuff is picked up.

I have the same issue on Debian Bullseye (or rather mixed Bullseye/Buster).
Package python3-distutils (3.8.6) contains module for Python 3.8 and 3.9 (!).
Old package (3.7.3) for Python 3.7. You have to choose.
My workaround is just copy module.
mkdir -p /usr/lib/python3.7/distutils
cp -a /usr/lib/python3.8/distutils/* /usr/lib/python3.7/distutils/
I have been trying to run a python file using rosrun command but unfortunately I am having this module not found error because of a package named rospkg. Until a day before yesterday, it was all working fine but yesterday, ubuntu18.04 has got some updates out of which an update for ubuntu base was also present, since that update I am having this error.
I have tried to check whether I have installed the respective python-rospkg and its says I already have the latest version. I have also using
echo $PYTHONPATH
to check the sourced paths and they are sourced correct, I am not sure whats causing this error.
the error is as follows

The shebang for my is as follows,

When i try to run the file by changing the shebang to

I get the following error

I have installed tensorflow version 1.14 using pip installation. Can anyone please help me solving this error. Thanks in advance
edit:
I have manually tried to set the python path to /usr/lib/python2.7/dist-packages as when I tried to install python-rospkg, it says the its already instaled in that location. Doing that I am having error importing tensorflow and the error is

The file usr/local/google-cloud-sdk/platform/google_appengine/lib/distutils/distutils/command/install.py has lines like this and is compatible with python 2.1. Note. this is not the official google repository but it's accurate:
print "config vars:"
This means that install.py is a python 2 file and you are running pip from python 3. There probably is some incompatibility between them.
I have already have a virtual environment installation of Tensorflow on my computer, although it runs Python 2.7. Now I want to work with Tensorflow running in Python 3.5.
For Python 3, I've created a virtual environment since the default Python environment on my computer is Python 2.7. I'm attempting a Pip installation of Tensorflow in a Python 3 virtual environment that I have named py3k. The installation procedure throws errors that I'm finding difficulty in debugging.
Here's what I did:

I found I can't install anything by pip under jython.
Please help me fix it, thanks.
I had the same problem trying to use pip for Jython2.7b3.
I downloaded this:
https://github.com/jythontools/pip/tree/master
And ran the command:
Jython setup.py install
And pip is now up and running like a charm.
