Cannot create .exe with pyinstaller from .py with torchaudio (CPU): AttributeError: '_OpNamespace' 'torchaudio' object has no attribute 'cuda_version'

I have a .py script that uses torchaudio (without GPU) to process some sound in Windows. To distribute it, I've used pyinstaller to turn it into a .exe. You can reproduce the issue with this simple script:
import torchaudio
import time
if __name__ == '__main__':
t = torchaudio.transforms
time.sleep(3)
print("Success")
This script correctly runs from a python console python test.py but I want to create a test.exe that works in Windows (without having python installed). I create test.exe by using pyinstaller: pyinstaller test.py. This creates a build/test folder with all the required dependencies (around 1GB). test.exe is located inside that folder but when I double click on it, it fails with the following error:
Traceback (most recent call last):
File "torch\_ops.py", line 501, in __getattr__
op, overload_names = torch._C._jit_get_operation(qualified_op_name)
RuntimeError: No such operator torchaudio::cuda_version
The above exception was the direct cause of the following exception:

The environment uses:

six==1.15.0

scipy==1.6.0
sounddevice==0.4.5
torchaudio==0.13.0
pyinstaller==5.6.2
Note: I tried the same installing torch with cuda ending up with the same error and a build 4 times bigger.

I was able to make the script work. Here are the steps I took to get it to run.
Create a new empty directory and pasted your script in as main.py
py -m venv venv && venv\scripts\activate && py -m pip install --upgrade pip pyinstaller
pip install torchaudio==0.13.0 torch==1.13.0 numpy=1.22.4 sounddevice==0.4.5 six==1.15.0 scipy
pyinstaller -F main.py
Go into venv\Lib\site-packages and copy the entire torchaudio folder and paste it into the top level directory alongside venv and main.py
In main.spec set datas=[('./torchaudio','./torchaudio')]
pyinstaller main.spec
And after compiling the executable runs... it still gives off a few warnings, but it runs and prints the success message.

I can't run a small script due to Foundation not being recognised

I am a new python programmer and was testing out pyttsx3, I am trying to use nsss. However when I run the following code
import pyttsx3
engine=pyttsx3.init('nsss')
engine.say ("Top of the morning")
# angine=pyttsx3.init()
# angine.say("Why hello there")
# angine.runAndWait()
It says error Foundation module not found, so I installed it with pip install foundation. This installs foundation and django version 1.10.8 which to my understanding is not compatible with python v 3.9. But when I install Django version 3.1.7, that version is not compatible with Foundation.
The error logs are below

install the necessary libraries and run in separate virtual environment
sudo apt-get install python-espeak
sudo apt-get update && sudo apt-get install espeak
using python3.9 with virtual environment,
python3.9 -m venv env
source env/bin/activate
pip install pyttsx3
now running the below demo code should work.

from pgadmin website:
Setup the repository
Install the public key for the repository (if not done previously):
sudo curl https://www.pgadmin.org/static/packages_pgadmin_org.pub | sudo apt-key add
Create the repository configuration file:
sudo sh -c 'echo "deb https://ftp.postgresql.org/pub/pgadmin/pgadmin4/apt/$(lsb_release -cs) pgadmin4 main" > /etc/apt/sources.list.d/pgadmin4.list && apt update'
Install pgAdmin
Install for both desktop and web modes:
sudo apt install pgadmin4
Install for desktop mode only:
sudo apt install pgadmin4-desktop
Install for web mode only:
sudo apt install pgadmin4-web
Configure the webserver, if you installed pgadmin4-web:
sudo /usr/pgadmin4/bin/setup-web.sh

As printed in log issue is in
File "/usr/lib/python3/dist-packages/paramiko/sftp_file.py", line 66
self._close(async=True)
The problem seems to be with the name choosen for the variable async set to True in the above example.
async is also a python command, so I suppose Python interpret async as the python command not a variable.
I renamed all async variable to aasync in file "/usr/lib/python3/dist-packages/paramiko/sftp_file.py" and then try to install python3-paramiko.
I have no error anymore.

Error in Hosting ReadTheDocs in house Server in python3

I am trying to install readthedocs in local system (Ubuntu 14.04 ) in python3 virtual env from the instructions given in this link
When I ran pip3 install -r requirements.txt , I got an error for Distutils2 . I removed that dependency as the distutils2 is no longer supported and assumed setuptools would suffice.

SyntaxError: Missing parentheses in call to 'print'
I understand from the above stacktrace that the code is in python2 and so print statement is different in python3 .
Does this mean that I have to install readthedocs in python2 virtualenv ?
Can't we host the docs of python3 projects in readthedocs in-house server ?

The read the docs code does not support Python 3 yet. The installation instructions explicitly say to use Python 2.7:
First, obtain Python 2.7 and virtualenv
However, it should still be possible to use your read the docs installation to host docs for Python 3 projects, since the instructions then say:
If you plan to import Python 3 project to your RTD then you’ll need to install Python 3 with virtualenv in your system as well.

django running in virtualenv gives syntax error after executing /usr/share/qgis... (not in virtualenv)

I'm running django using a virtualenv. For some reason, django calls httplib2 in /usr/share/qgis/python/httplib2... where there's a syntax error for some reason.
This never happened before I installed the qgis library from arch's AUR.
I don't understand why is it calling the library that's in qgis? I have this same library in the virtualenv and also on the file system (installed after the error popped-up):
[root#arch http]# pacman -Ql | grep httplib2
...
python-httplib2 /usr/lib/python3.4/site-packages/httplib2/
...
This is information abuot my virtualenv:
(app)[jenia#arch merging_map_]$ python --version
Python 3.4.1
(app)[jenia#arch merging_map_]$ pip freeze
Django==1.6.5
Pillow==2.5.1

python-social-auth==0.1.26
python3-openid==3.0.4
requests==2.3.0
requests-oauthlib==0.3.1
six==1.7.3
Here is the trace back. Its a little long, i think the most interesting is the last lines (the top of the stack). It says that that django tried to use a library in /usr/share/qgis...

Thanks in advance for your time and kind help.

How in the world did the qgis folder get into the virtualenv exec paths i dont know. please tell me how to get it out!! and how to replace it with the correct python path.

So it seems that the problem is that library is in PYTHONPATH. You can remove it just doing
$ unset PYTHONPATH
$ source /path/to/venv/bin/activate
Now regarding how it got there: probably you installed something (QGIS) that add it there. You can try to find it where it is defined and remove it
$ grep -r "PYTHONPATH" /etc
Also you should check in your .bashrc and .profile files in your home folder. Of course if you remove that entry from python path, the software that needs it may stop working...
